S-93445A376 10-32 x 1/2" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional thread precision with Class 3A fit ensures tight, secure fastening with minimal backlash
• Enhanced locking capability through serrations that resist loosening under vibration and dynamic loads
• Optimized torque transmission with 3/32" hex drive for reliable installation without stripping
• Maximum holding power from the cup tip design that digs into surfaces for permanent positioning
• Consistent mechanical performance backed by Rockwell B80 hardness for durability and wear resistance
• Space-saving headless design allows for flush mounting in confined assemblies

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw delivers critical reliability in precision assemblies where vibration resistance and permanent positioning are paramount. The 18-8 stainless steel material provides excellent corrosion resistance for machinery, automotive, and electronic enclosures exposed to moisture or chemicals. Its fine thread spacing and cup tip work synergistically to penetrate shaft surfaces without causing stress fractures, preventing component slippage in high-torque applications. The headless design with 3/32" hex drive enables tool access in tight spaces while maintaining a clean profile. Engineered to ASME B18.3 specifications, it ensures dimensional consistency for repeatable performance in automated production lines and maintenance operations.

Specification Summary & Compliance

This set screw maintains Class 3A thread fit per UNF standards with 10-32 thread size, 1/2" length, and 0.19" thread diameter. Manufacturing conforms to ASME B18.3 for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability for global industrial supply chains.
