Understanding HIDfast Hidden Decking Fastener Technology
HIDfast hidden decking fasteners represent an innovative approach to creating clean, fastener-free deck surfaces that has gained significant traction among professional deck builders. Unlike traditional clip systems or bracket-based fasteners, HIDfast uses a unique screw-based design that allows the fastener to be driven through the side of the deck board at an angle, effectively hiding the screw head within the gap between boards. The system works by driving specially designed screws through the side edge of one deck board and into the adjacent board, creating a mechanical connection between boards that eliminates the need for visible fasteners on the walking surface. This side-fastening approach combines the simplicity of screw installation with the aesthetic benefits of hidden fastening, making it an attractive option for contractors and homeowners who want professional results without the complexity of clip-based systems. For builders seeking efficient, reliable methods for creating beautiful deck surfaces, understanding the HIDfast system and its proper application is essential knowledge for modern deck construction.
The HIDfast system consists of two main components: the specialized HIDfast screws and a proprietary installation tool or jig that guides the screw at the correct angle and depth. The screws are designed with a unique head geometry that allows them to be driven below the surface of the board edge, and they include self-drilling tips that eliminate the need for pre-drilling in most decking materials. The installation tool positions the screw at the optimal angle for maximum holding strength while ensuring that the screw head ends up hidden within the gap between boards. The result is a deck surface that appears to have no fasteners at all, with clean, uninterrupted sightlines that showcase the beauty of the decking material. The following table compares HIDfast with other hidden decking fastening technologies.
| Fastening Technology | Installation Method | Board Compatibility | Speed of Installation | Tool Investment | Removability |
|---|---|---|---|---|---|
| HIDfast screw system | Screw driven at angle through board edge | Any solid deck board (wood, composite) | Fast with specialized tool | Moderate – specialized jig/driver | Good – screws accessible from gap |
| Tiger Claw clips | Clip + screw from below | Grooved boards only | Fastest with pneumatic gun | High – pneumatic gun required | Moderate – clips under boards |
| The Eliminator brackets | Brackets on joists | Any board type | Moderate | Low – standard tools only | Good – brackets accessible from below |
| Camouflage screws | Screw through board face | Solid wood boards | Fast | Low – standard screw gun | Good – screws visible |
The engineering behind the HIDfast screw design focuses on achieving maximum holding strength while minimizing the visual impact of the fastener. The screw thread is designed to create a strong mechanical bond with both the board being fastened and the adjacent board, effectively clamping the two boards together while pulling them down against the joist. The screw geometry ensures that the fastener does not split the board edge during installation, even in dense tropical hardwoods such as ipe, cumaru, or garapa that are notoriously difficult to fasten without pre-drilling. The self-drilling tip reduces installation time and eliminates the need to change bits between drilling and driving, making the HIDfast system comparable in installation speed to standard face-screwing while providing superior aesthetic results.
Installation Methods and Best Practices for HIDfast Systems
Proper installation of HIDfast hidden decking fasteners requires attention to several critical factors that affect the performance and appearance of the finished deck. The HIDfast installation tool or jig must be correctly set for the thickness of the deck boards being installed, typically 5/4 inch or 2 inch nominal thickness. The tool positions the screw at the correct angle relative to the board surface, typically 30 to 45 degrees from vertical, ensuring that the screw passes through the board edge and into the adjacent board at the optimal angle for maximum holding strength. The depth stop on the tool must be adjusted so that the screw head is driven below the surface of the board edge, completely hidden within the gap when the adjacent board is installed. If the depth is set too shallow, the screw head will be visible in the gap, defeating the purpose of the hidden fastening system.
The sequence of installation for HIDfast begins with the first row of deck boards, which are typically face-screwed along the outer edge where the fastener heads will be covered by the fascia board. After the first board is secured, the HIDfast screws are driven through the exposed edge of the first board at each joist location, using the installation tool to ensure consistent angle and depth. The screws should be positioned approximately 1/2 inch to 3/4 inch below the top surface of the board to allow room for the screw head within the gap. After all screws are installed in the first board, the next board is positioned against the first board, and as the board is pressed into place, the HIDfast screws penetrate the edge of the second board, creating a secure mechanical connection. The second board is then fastened to the joists using standard face screws on its opposite edge, and the process repeats across the deck. For decks with irregular board widths or complex layouts, additional care is needed to ensure that the screw positions align with joist locations and that the gap between boards remains consistent.
The compatibility of HIDfast with different decking materials is an important consideration for material selection. The system works well with most softwood decking materials including pressure-treated pine, cedar, and redwood, as well as with tropical hardwoods and composite decking materials that have sufficient density to hold the screw threads. For very dense hardwoods or for boards with irregular grain patterns, pre-drilling at the screw locations may be recommended to prevent splitting, even with the self-drilling tip design. The manufacturer’s recommendations for specific decking materials should always be consulted before installation, and sample installations should be tested on scrap material to verify that the screws drive cleanly and hold securely without damaging the board edges. The composite decking materials and installation guide provides detailed information on selecting decking products that are compatible with various hidden fastening systems.
Advantages and Limitations of HIDfast Hidden Fasteners
The primary advantage of the HIDfast system over other hidden fastening approaches is its compatibility with any solid deck board, eliminating the need for factory-grooved edges that are required by clip-based systems. This compatibility allows builders to use a wider range of decking materials, including locally sourced lumber, specialty hardwoods, and composite boards that do not have factory grooves. The ability to use any board type also simplifies material procurement and reduces the risk of project delays caused by material availability issues. For builders who work with multiple decking materials across different projects, the HIDfast system provides a single fastening solution that works with all of them, reducing the need to stock multiple fastener types and installation tools.
The installation speed of the HIDfast system compares favorably with other hidden fastening methods, particularly for experienced installers who have developed proficiency with the specialized tool. The process of driving screws through the board edge is inherently faster than installing individual clips or brackets at each joist location, and the elimination of the grooved board requirement removes the need to verify groove compatibility and alignment. However, the HIDfast system does require more precision in screw placement than face-screwing, as misaligned or incorrectly angled screws can be visible in the gap or can cause board splitting. Training and practice are essential for achieving consistent, professional results, and new users should expect a learning curve before reaching maximum installation speed.
One limitation of the HIDfast system is that it requires access to the board edge for screw installation, which can be challenging when installing the last board in a row or when working in tight spaces where the installation tool does not fit. The system may also require additional planning for deck boards that are installed at an angle or in complex patterns, as the screw angle relative to the board edge must be maintained for proper engagement. For decks with curved edges, irregular shapes, or multiple changes in board direction, alternative fastening methods may be more practical for certain sections of the deck. Despite these limitations, the HIDfast system remains a popular choice for its combination of clean appearance, material flexibility, and straightforward installation process.

Cost Considerations and Return on Investment for HIDfast Systems
The cost of the HIDfast hidden fastening system includes both the specialized screws and the installation tool or jig. The HIDfast screws are priced at a premium compared to standard deck screws, typically costing $0.15 to $0.30 per screw depending on quantity and retailer. For a standard deck with joists spaced at 16 inches on center, approximately 8 to 10 screws are required per board, resulting in a fastener cost of $1.20 to $3.00 per board or approximately $0.40 to $1.00 per square foot of deck surface. The installation tool represents an additional investment of $100 to $300, which should be amortized over the expected number of deck projects. When compared to concealed clip systems that cost $0.60 to $1.20 per square foot for clips plus the cost of the installation gun, the HIDfast system is cost-competitive while offering the advantage of compatibility with non-grooved boards.
The labor savings from using the HIDfast system compared to manual clip installation can offset the higher material costs for professional contractors. An experienced installer can typically install 200 to 300 square feet of HIDfast decking per day, comparable to the installation speed of clip-based systems but without the requirement for grooved boards that may cost more than standard ungrooved boards. The ability to use standard lumber without the premium charged for grooved decking can result in material savings of $0.50 to $1.00 per square foot, offsetting much of the additional cost of the HIDfast fasteners. For projects where the decking material cost is a significant portion of the total budget, the flexibility to select the most cost-appropriate board material can make the HIDfast system more economical overall than clip-based alternatives.
The long-term value of the HIDfast system is realized through the elimination of maintenance issues associated with visible fastener heads. Deck surfaces with no visible fasteners do not develop rust stains, do not collect dirt around screw heads, and do not present tripping hazards from loose or raised fasteners. The clean surface is easier to clean and maintain, and the deck retains its attractive appearance for longer between maintenance cycles. For homeowners who prioritize appearance and low maintenance, the premium paid for a hidden fastening system like HIDfast is justified by the aesthetic and functional benefits that persist throughout the life of the deck. When combined with high-quality decking materials and proper substructure construction, the HIDfast hidden fastening system delivers a deck surface that combines beauty, durability, and ease of maintenance that justifies the investment for both new construction and deck renovation projects.
