Professional Applications & Engineering Value

These No. 6 wood screws with thread forming technology deliver exceptional performance in wood fastening applications by eliminating the need for pre-tapped holes. The zinc-plated steel construction provides reliable corrosion protection, making them suitable for interior woodworking projects, furniture assembly, cabinetry, and general construction. The partially threaded design ensures maximum holding strength while minimizing wood splitting, particularly important when working with delicate hardwoods. The standard 82° flat head profile allows for flush mounting, creating clean, professional finishes without protruding hardware. With precise drill bit specifications for both hardwood and softwood applications, these screws eliminate guesswork and ensure proper fitment every time, reducing installation errors and material waste in professional woodworking operations.

Specification Summary & Compliance

This No. 6 x 1/2" wood screw features a 0.138" thread diameter with 18 threads per inch in a right-hand thread direction. The screw is manufactured with a partially threaded shank design and standard flat head profile compatible with 82° countersinks. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring responsible production practices and material safety.
