S-92695A643 10-32 x 7/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with a 90° cone point that bites deeply into materials for secure, permanent fastening
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in demanding environments
• High-strength durability with a Rockwell C45 hardness rating, resisting wear and deformation under heavy loads
• Precise, reliable engagement due to the Class 3A thread fit and UNF fine threads, ensuring tight tolerances and vibration resistance
• Easy installation in confined spaces with a headless design and 3/32" hex drive for straightforward tool access
• Broad industry compliance meeting ASME B18.3 standards, RoHS 3, and REACH for quality and environmental safety
• Optimized for right-hand thread applications providing consistent performance in standard assembly processes

Professional Applications & Engineering Value

This 10-32 UNF set screw is engineered to solve critical fastening challenges in precision machinery, automotive components, and industrial equipment. The black-oxide alloy steel construction combined with a Rockwell C45 hardness ensures it withstands high-stress conditions without loosening, while the 90° cone point concentrates force for maximum grip on shafts, collars, and gears. Its headless design and hex drive allow for flush mounting in tight spaces, reducing assembly bulk. The Class 3A thread fit and fine thread spacing provide superior resistance to vibration and thermal cycling, making it ideal for applications demanding repeatable accuracy and long-term reliability. By integrating these features, the screw minimizes maintenance downtime and enhances the structural integrity of assembled parts.

Specification Summary & Compliance

This set screw adheres to Class 3A thread fit tolerances per UNF standards, ensuring precise dimensional accuracy with a thread diameter of 0.19" and fine spacing. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial use without hazardous substances.
