S-92311A425 10-32 x 1/4" 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
• Precise Class 3A thread fit ensures tight, secure fastening with minimal backlash in fine thread applications
• High-strength performance backed by Rockwell B80 hardness for reliable, long-term holding power
• Secure hex drive engagement with 3/32" drive size prevents cam-out and allows for high-torque installation
• Effective component positioning through cup point tip design that creates positive seating in shafts and collars
• Space-saving headless design enables flush mounting in applications with limited clearance
• Industry-standard compliance with ASME B18.3 specifications ensures consistent quality and interchangeability

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw delivers exceptional engineering value in precision assembly applications where fine thread engagement and reliable positioning are critical. The 18-8 stainless steel composition provides excellent corrosion resistance for demanding environments including manufacturing equipment, automotive components, and electronic enclosures. The cup point tip creates positive indentation on shaft surfaces, preventing slippage in power transmission systems and rotating assemblies. With its headless design and compact 1/4" length, this fastener solves space-constrained installation challenges while maintaining superior holding power through the 3/32" hex drive that withstands high installation torque without stripping.

Specification Summary & Compliance

This precision set screw features 10-32 UNF fine threads with Class 3A tolerance for tight fitment, measuring 1/4" in length with 0.19" thread diameter. Manufactured to ASME B18.3 specifications with right-hand thread direction and Rockwell B80 hardness. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for restricted substance control.
