Professional Applications & Engineering Value
These No. 4 brass wood screws deliver exceptional engineering value through their specialized thread forming design and partially threaded construction. The brass material provides natural corrosion resistance that prevents staining and degradation in wood applications, while the Phillips drive system ensures reliable installation without stripping. The 22 TPI precision threading and pointed tip allow for clean penetration in both hardwood and softwood, minimizing material stress and splitting. These features make them ideal for woodworking projects requiring both structural integrity and aesthetic appeal, from furniture assembly to architectural woodwork where environmental compliance and long-term performance are critical considerations.
Specification Summary & Compliance
These inch-system screws feature a 0.112" thread diameter with 22 TPI precision threading and right-hand thread direction. The partially threaded design provides optimal grip length with 1/2" minimum thread length on a 3/4" overall screw length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in commercial and residential applications. The rounded head profile with 0.211" diameter and standard head style provides consistent performance across wood fastening applications.
