- Precision fit and reduced installation effort with recommended 5/64" drill bit for accurate pilot holes
Professional Applications & Engineering Value
These 316 stainless steel wood screws are engineered to address common failure points in wood and plastic-wood composite applications, where moisture, chemicals, and stress can degrade fastener integrity. The Type 17 thread cutting design and 15 TPI configuration ensure minimal material displacement and reduced splitting, especially in brittle composites. Combined with the square drive for high-torque installation, these screws deliver consistent performance in outdoor structures, marine fixtures, and industrial wood assemblies. The flat head and partial threading further enhance load distribution and withdrawal resistance, making them a durable, corrosion-proof solution for long-term fastening needs.
Specification Summary & Compliance
This No. 8 screw features a 1 5/8" length, 0.164" thread diameter, and right-hand threading per standard inch-series specifications. The thread cutting (tapping) method and Type 17 screw design comply with common industrial standards for wood and composite fastening. Manufacturing adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted hazardous substances for safe, compliant use in global markets.
