Carbon Steel Wood Screws
Product Overview
This high-performance Ruspert anti-corrosion wood screw is a high-strength self-tapping fastener crafted specifically for wood structure fastening scenarios. It adopts an integrated structural design featuring a grid-patterned anti-slip countersunk head, breaking ribs (recessing ribs), and a slot-point sharp tip, and is coated with an eco-friendly Ruspert anti-corrosion coating. Combining high installation efficiency, strong connection performance, and long-lasting rust prevention, it stands as the preferred accessory for outdoor use, preservative wood engineering, and wood structure installations in indoor humid environments.
Product Applications
Applicable to outdoor preservative wood decks, fences, and log cabin framing; wallboard/furniture installation in indoor humid environments; as well as the fastening and connection of heavy wood structures like hardwoods and multilayer boards.
Product Features
Grid-Patterned Anti-Slip Phillips Countersunk Head: Accommodates universal driver bits, with the knurled grid pattern preventing slippage; the countersunk head can bury completely into the wood without affecting the flatness of the finish.
Breaking Ribs (Recessing Ribs) Design: Enhances pull-out resistance and prevents loosening while reducing the expansion stress of the wood, effectively avoiding board splitting.
Slot-Point Sharp Tip Structure: Comes with self-tapping capability, eliminating the need for pre-drilling; the cutting slot evacuates chips and reduces resistance, allowing easy driving even into hardwoods.
Ruspert Anti-Corrosion Coating: Its rust-preventative capability far exceeds regular zinc plating, withstanding 500 to 1,500 hours in salt spray testing. It is suitable for outdoor and humid environments with zero risk of hydrogen embrittlement.
