Professional Applications & Engineering Value
These 8-32 UNC zinc-plated steel screws deliver critical performance advantages for industrial assembly and construction applications. The coarse thread design provides superior pull-out resistance in wood, plastic, and sheet metal, while the zinc plating creates a protective barrier against corrosion in demanding environments. The fully threaded configuration ensures maximum thread engagement throughout the entire 2" length, distributing stress evenly and preventing joint failure. With 60,000 psi tensile strength and Rockwell B69 hardness, these rounded head Phillips screws maintain structural integrity in high-vibration applications, making them ideal for machinery, electrical enclosures, and structural frameworks where reliability is paramount.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threads (8-32 size) in right-hand direction. Complies with ASME B18.6.3 dimensional standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features standard rounded head profile with 0.309" diameter and Phillips No. 2 drive system for consistent performance across industrial applications.
