S-92695A629 6-32 x 5/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating that protects against rust in demanding industrial environments
• Exceptional holding power from the 90° cone point design that bites deeply into mating surfaces for secure fastening
• Precision thread engagement with Class 3A fit ensuring tight tolerances and reliable performance in vibration-prone applications
• High-strength durability from alloy steel construction with Rockwell C45 hardness for repeated use without deformation
• Easy installation in confined spaces thanks to the headless design and compact 1/16" hex drive
• Wide compatibility with UNC coarse threads that provide quick assembly and disassembly in various industrial components
• Regulatory compliance assurance meeting ASME B18.3 standards for consistent quality and performance

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent positioning are paramount. The 90° cone point creates concentrated pressure points that prevent shaft slippage in pulleys, gears, and collars, while the UNC coarse threads provide excellent engagement in both soft and hard materials. The headless design with hex drive allows for flush mounting in space-constrained assemblies, making it ideal for machinery, automotive components, and precision equipment. With Rockwell C45 hardness, this fastener maintains its structural integrity under repeated stress cycles, eliminating the need for frequent replacements in high-vibration environments common to manufacturing and automation systems.

Specification Summary & Compliance

This set screw features precision 6-32 UNC coarse threads with Class 3A fit for superior thread engagement and dimensional accuracy. Manufactured to ASME B18.3 specifications with ASTM F912 compliance, ensuring consistent quality and performance. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental regulations for industrial use. The black-oxide surface treatment provides additional corrosion protection while maintaining the alloy steel's mechanical properties.
