S-92991A824 10-32 x 3/16" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass material, ideal for humid or chemically aggressive environments
• Precise Class 3A thread fit ensures tight, secure fastening with minimal backlash in critical assemblies
• Enhanced torque transmission via 3/32" hex drive, preventing tool slippage and reducing installation damage
• Excellent holding power with cup tip design that bites into shafts for reliable positioning without loosening
• Consistent dimensional accuracy meeting ASME B18.3 specifications for interchangeability in production runs
• Optimized mechanical strength with Rockwell B55 hardness balancing durability and machinability
• Full regulatory compliance with RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

This 10-32 UNF brass set screw delivers exceptional performance in precision mechanical systems where corrosion resistance and dimensional stability are critical. The Class 3A thread fit provides superior engagement in threaded holes, eliminating play in sensitive instrumentation and rotating assemblies. The headless design with cup tip creates positive locking action on shafts and collars, while the fine UNF thread offers higher tensile strength compared to coarse threads. Manufactured to ASME B18.3 standards, these set screws maintain consistent quality in automated production environments, particularly in electrical enclosures, marine equipment, and precision machinery where galvanic corrosion must be avoided.

Specification Summary & Compliance

This brass set screw features 10-32 UNF fine threads with Class 3A tolerance for precision fit, 3/16" length, and 3/32" hex drive. Manufactured according to ASME B18.3 specifications with Rockwell B55 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for hazardous substance restrictions.
