Product Overview
100mm Hex Head Timber Screws for medium-duty structural timber fixings and decking frames. Each screw is made from heat-treated carbon steel for maximum torsional strength and long-term performance.
A Ruspert-coated surface provides advanced corrosion resistance through a three-layer metallic system comprising a zinc base coat, chemical conversion film, and ceramic top layer.
The hexagonal drive head with integral washer face ensures high clamping pressure, preventing timber movement and pull-through under load. The coarse thread delivers fast cutting and high pull-out resistance in softwood, treated wood, and heavy sections.
A gimlet point - a self-tapping, tapered tip - allows for fast starting and penetration without the need for full pre-drilling, saving installation time while reducing timber splitting.
Features & Benefits
- Material strength: Heat-treated carbon steel provides superior torsional and shear strength.
- Ruspert coating: Three-layer corrosion protection (zinc, film, ceramic) ensures extended outdoor durability.
- Hex washer head: Provides maximum grip for high-torque driving and broad surface contact for secure clamping.
- Coarse thread: Rapid drive and strong hold in softwood, green oak, and pressure-treated timber.
- Gimlet point: Self-starting tapered tip enables direct penetration and reduces splitting.
- Nominal size: 100mm length.
- Application range: Medium structural joinery, deck subframes, and general outdoor builds.
Applications
- Deck subframes: Fastening joists, bearers, and rails.
- Timber framing: Reliable for garden buildings and fence structures.
- Medium posts and beams: Suitable for 4x2 and 6x2 sections.
Installation Guidance
- Pilot drilling: Recommended in dense or dry hardwoods for best accuracy.
- Driving method: Use a power driver with compatible hex socket for consistent torque.
- Head seating: Drive until the washer face seats firmly; avoid over-tightening.
- Best practice: Maintain spacing between fixings to prevent end-grain splitting.
Compliance & Performance
- Manufacturing reference: Produced in accordance with EN 14592 for timber fasteners.
- Coating performance: Ruspert finish provides tested corrosion resistance suitable for standard exterior exposure.
- Safety: Use eye protection and stable work support when fixing.
- Important note: For coastal or permanently damp installations, stainless steel fixings are recommended.
