S-92785A582 1/2"-13 x 1" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for reliable, vibration-resistant fastening in demanding applications
• Excellent corrosion resistance from 18-8 stainless steel construction, ensuring long-term performance in harsh industrial environments
• Maximum grip and alignment with 90° cone point design that bites deeply into mating surfaces
• Enhanced durability with Rockwell B80 hardness for repeated use without deformation or wear
• Easy installation and removal using standard 1/4" hex key tools for efficient maintenance
• Reliable coarse threading (UNC) that resists loosening under vibration and provides quick assembly
• Space-saving headless design ideal for applications where clearance is limited

Professional Applications & Engineering Value

This 1/2"-13 UNC Class 3A set screw delivers exceptional engineering value through its 18-8 stainless steel composition and precision cone point design. The 90° cone point angle creates concentrated pressure points that prevent slippage in rotating components like gears, pulleys, and collars. The Class 3A thread fit ensures tight tolerances that eliminate play in precision machinery, while the coarse thread spacing provides superior resistance to vibrational loosening in industrial equipment. With Rockwell B80 hardness, this hex headless set screw maintains its structural integrity through repeated adjustments, making it ideal for permanent positioning applications in manufacturing, automation, and heavy machinery where reliability is critical.

Specification Summary & Compliance

This set screw features 1/2"-13 UNC coarse threads with Class 3A fit for precision tolerance, 1" length, and 0.5" thread diameter. Manufactured to ASME B18.3 specifications with right-hand thread direction and 1/4" hex drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
