Professional Applications & Engineering Value
Engineered for high-performance industrial fastening, this black-oxide alloy steel screw addresses common challenges like corrosion, vibration-induced failure, and assembly efficiency. The Class 3A UNC coarse thread provides a secure fit in materials prone to stripping, while the rounded head with hex drive allows for tight spaces and high-torque applications without cam-out. Its flanged design distributes clamping force evenly, protecting surfaces in machinery, automotive assemblies, and electrical enclosures. With a Rockwell C32 hardness and 120,000 psi tensile strength, it withstands heavy loads and repetitive stress, making it ideal for durable construction in manufacturing and maintenance operations.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 3A thread fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances. Manufacturing specifications include a fully threaded design, right-hand thread direction, and 1" length with consistent 0.164" thread diameter, supporting reliable performance in regulated industrial applications.
