Wood Screws Torx Star Drive without anti theft pin Deck Screw Flat Head Countersunk Self Tapping Thread Bolt Stainless Steel 304 18-8

描述

1.Exceptional Corrosion Resistance & Mechanical Strength
Forged from 18-8 (304) stainless steel, these deck screws offer a tensile strength of ≈515 MPa, yield strength of ≈205 MPa and ~80 HRB hardness. The fully passivated, polished finish provides outstanding resistance to rust, salt spray and harsh chemicals—ideal for coastal and exterior environments.

2.Wide-Ranging Outdoor Applications
Engineered for fastening hardwood and softwood decking, composite boards, fencing, pergolas, exterior trim, marine fixtures and playground equipment. The flat, countersunk head ensures a smooth, snag-free surface while accommodating 12–38 mm board thicknesses without splitting.

3.Effortless, Accurate Installation
The Torx-star drive (T15–T30) guarantees self-centering engagement and high torque transfer (up to 12 Nm) with virtually no cam-out. Combined with a Type-17 self-tapping point and optimized coarse thread, these screws cut their own pilot path—no pre-drilling required and reduced wood splitting.

4.Certified Quality & Long-Term Durability
Manufactured in ISO 9001–certified facilities to ANSI/DIN tolerances (±0.1 mm). Each batch undergoes dimensional inspection, drive-torque testing and ≥240 h salt-spray per ASTM B117. Full material traceability and RoHS compliance ensure consistent, reliable performance over years of service.
