S-91428A131 Length 6" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for humid or chemically aggressive woodworking environments
• Enhanced holding power through thread forming technology that creates stronger, more permanent connections in wood materials
• Simplified installation process with pointed tip design and partial threading for reduced driving torque and split prevention
• Secure flange integration eliminates the need for separate washers while providing superior load distribution
• Robust external hex drive delivers maximum torque transfer during installation with standard wrench tools
• Extended 6" length accommodates thick wood assemblies and provides deep penetration for critical structural applications
• Environmental compliance assurance with RoHS 3 and REACH standards for safe, regulated industrial use

Professional Applications & Engineering Value

Engineered specifically for demanding wood construction applications, these 316 stainless steel flanged hex head wood screws address critical challenges in outdoor structures, marine environments, and industrial wood assemblies. The thread forming design creates compressed wood fibers around the threads, significantly increasing pull-out resistance compared to conventional cutting threads. This feature is particularly valuable in softwoods and composite materials where strip-out prevention is essential. The flanged hex head configuration provides dual benefits: the integrated flange distributes clamping force over a wider surface area, while the external hex drive accommodates high installation torque without cam-out issues. The partial threading ensures unthreaded shank sections maintain material integrity in critical shear applications, making these screws ideal for structural wood connections exposed to moisture, chemicals, or temperature variations where corrosion resistance is paramount.

Specification Summary & Compliance

These 1/4"-7 x 6" wood screws feature inch system measurements with 0.25" thread diameter and 7 threads per inch configuration. The partially threaded design provides approximately 2.95" of thread length with a smooth shank section. Manufacturing complies with industry standards for external hex drive fasteners and thread forming screw specifications. Environmental compliance is verified through RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance regarding substance restrictions, ensuring adherence to current European regulatory requirements for industrial fasteners.
