S-91375A452 10-32 x 2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating on alloy steel, extending service life in harsh environments
• Precise thread engagement with Class 3A fit for reliable, vibration-resistant fastening in critical assemblies
• High-strength performance backed by Rockwell C45 hardness, ensuring durability under heavy loads
• Secure installation using 3/32" hex drive, preventing cam-out and enabling consistent torque application
• Effective component positioning with cup tip design that bites into surfaces without slipping
• Space-saving headless construction ideal for confined spaces where protruding fasteners aren't feasible
• Industry-standard compliance meeting ASME B18.3 specifications for guaranteed interchangeability

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw delivers exceptional performance in demanding industrial applications where vibration resistance and precise component positioning are critical. The black-oxide alloy steel construction provides superior corrosion protection while maintaining the material's inherent strength, making it ideal for machinery, automotive components, and precision equipment assemblies. The fine thread spacing of the UNF thread form ensures maximum engagement in softer materials or thin-walled applications, while the cup tip design creates positive locking action that prevents shaft slippage under rotational forces. Engineered for headless installation with hex drive convenience, this fastener solves alignment challenges in space-constrained assemblies where traditional bolt heads would interfere with adjacent components.

Specification Summary & Compliance

This precision set screw features 10-32 UNF threads with Class 3A thread fit for tight tolerance applications, manufactured to ASME B18.3 specifications where applicable per ASTM F912. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. With a standardized 2" length and 0.19" thread diameter, this component delivers consistent performance in industrial fastening systems requiring reliable, repeatable installation.
