Professional Applications & Engineering Value

This zinc-plated steel rounded head screw delivers critical performance advantages for industrial fastening systems where corrosion resistance and mechanical strength are paramount. The 1/2"-13 UNC coarse thread configuration provides exceptional pull-out resistance in metal assemblies, wood construction, and heavy equipment applications. Engineers specify this fully threaded fastener for its consistent clamping force distribution across the entire 2" length, eliminating weak points in critical joints. The combination of 60,000 psi tensile strength and Rockwell B69 hardness ensures reliable performance in high-vibration environments while the slotted drive maintains compatibility with standard installation tools across maintenance operations.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerances for consistent assembly performance. The UNC coarse thread (13 TPI) maintains proper engagement while the zinc-plated steel construction meets corrosion protection requirements. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for use in regulated industries. Standard right-hand thread direction with 0.5" thread diameter and 0.813" head diameter ensures interchangeability with existing industrial fastening systems.
