S-91375A823 10-32 x 1" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating, extending service life in harsh industrial environments
• Exceptional thread precision with Class 3A fit for reliable, vibration-resistant fastening in critical assemblies
• High-strength durability from alloy steel with Rockwell C45 hardness, preventing deformation under heavy loads
• Secure installation enabled by hex drive design, allowing high torque application without slippage
• Optimized grip from cup tip configuration, minimizing component movement in rotating machinery
• Regulatory compliance with ASME B18.3, RoHS 3, and REACH standards for global manufacturing acceptance
• Space-saving headless design ideal for confined applications where protruding fasteners are impractical

Professional Applications & Engineering Value

This 10-32 UNF set screw delivers critical engineering solutions for industrial equipment requiring precise component positioning. The zinc plated alloy steel construction combats corrosion in manufacturing environments while maintaining Rockwell C45 hardness to withstand rotational forces and vibration. The fine thread spacing and Class 3A thread fit create superior clamping force for shafts, collars, and gears, preventing slippage in high-torque applications. The headless design with hex drive enables flush mounting in space-constrained assemblies, while the cup tip provides concentrated contact pressure for secure fastening in automation systems, machinery, and precision instruments.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with Class 3A thread fit precision for superior dimensional accuracy. The 10-32 UNF fine thread configuration ensures consistent engagement while the 1" length provides optimal fastening depth. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use across global industrial applications.
