S-92991A143 6-32 x 3/16" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with brass construction for long-lasting performance in harsh environments
• Maximum holding power ensured by Class 3A thread fit for secure, vibration-resistant fastening
• Easy installation in confined spaces with compact 1/16" hex drive and headless design
• Enhanced material durability from Rockwell B55 hardness preventing deformation under stress
• Reliable grip on components thanks to cup tip design that minimizes surface damage
• Wide industrial compatibility with standardized 6-32 UNC coarse threads for easy replacement
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

This brass set screw delivers critical engineering solutions where corrosion resistance and precision threading are paramount. The 6-32 UNC coarse thread with Class 3A fit provides exceptional clamp load retention in vibrating assemblies, while the headless design and compact 1/16" hex drive enable installation in space-constrained machinery components. Manufactured to ASME B18.3 specifications, it ensures dimensional consistency for OEM and maintenance applications in electrical enclosures, precision instruments, and marine equipment. The cup tip concentrates force without marring shafts, making it ideal for permanent positioning of gears and pulleys where disassembly is infrequent.

Specification Summary & Compliance

This set screw maintains Class 3A thread fit per UNC standards with 6-32 thread size, 0.138" diameter, and 3/16" length. Manufacturing conforms to ASME B18.3 dimensional requirements, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for hazardous substance restrictions.
