• Enhanced material hardness at Rockwell B80 providing excellent resistance to wear and deformation under load
• Reliable positioning capability with cup point tip design that bites into surfaces for permanent component alignment
• Industry-standard compatibility with 1/2"-13 UNC coarse threads ensuring easy replacement and broad application use
• Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards including RoHS 3 and REACH

Professional Applications & Engineering Value

This 316 stainless steel set screw delivers exceptional performance in demanding industrial environments where corrosion resistance and mechanical reliability are paramount. The headless hex drive design provides flush mounting capabilities while enabling high torque application without protruding components. Engineered with Class 3A thread fit and UNC coarse threads, it ensures vibration-resistant fastening in machinery, automotive assemblies, and marine equipment. The cup point tip creates permanent seating by biting into shaft materials, preventing rotational slippage in high-stress applications. With Rockwell B80 hardness, this fastener maintains structural integrity under repeated loading cycles, making it ideal for permanent installations in manufacturing equipment, conveyor systems, and precision instruments where maintenance access is limited.

Specification Summary & Compliance

This 1/2"-13 UNC set screw features precise Class 3A thread fit tolerances with coarse thread spacing for optimal engagement. Manufactured to ASME B18.3 specifications, it ensures dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, confirming environmental safety and restricted substance adherence. With right-hand thread direction and 1½" length, this industrial-grade fastener meets rigorous quality standards for critical assembly applications.
