Professional Applications & Engineering Value
Engineered for precision and resilience, these black-oxide alloy steel socket head cap screws address common industrial challenges such as vibration loosening and corrosion. The 1-64 UNC coarse thread with a Class 3A fit ensures minimal backlash and reliable fastening in dynamic environments, from automotive assemblies to heavy machinery. The fully threaded rod type distributes load evenly, preventing joint failure in high-torque applications. With a Rockwell C37 hardness and robust hex drive, these screws withstand repetitive use without compromising integrity, making them ideal for industrial fasteners in manufacturing, aerospace, and electronics where durability and compliance are critical.
Specification Summary & Compliance
This product adheres to precise dimensional standards, including Class 3A thread fit for accuracy and UNC coarse threads for consistent engagement. It meets ASTM A574 specifications for alloy steel socket head cap screws, ensuring material quality and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it supports environmental and safety requirements in global supply chains.
