Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications requiring permanent positioning and torque transmission. The Class 3A thread fit with UNC coarse threads ensures superior resistance to loosening under vibration, making it ideal for machinery, automotive components, and precision equipment. The hex drive configuration allows for high-torque installation without stripping, while the headless design provides flush mounting in space-constrained assemblies. Engineered with Rockwell C45 hardness, it maintains dimensional stability under repetitive stress, preventing deformation in high-load scenarios commonly encountered in manufacturing and mechanical systems.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision, this set screw features 3/8"-16 UNC coarse threads and 1-3/4" length. The black-oxide alloy steel construction meets Rockwell C45 hardness requirements for optimal strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial reliability across global markets.
