S-92695A130 6-32 x 1/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit ensuring precise, vibration-resistant connections in demanding applications
• Enhanced corrosion resistance through black-oxide coating on alloy steel, extending service life in industrial environments
• Optimal hardness and durability with Rockwell C45 rating, preventing deformation under high torque and repeated use
• Secure, flush mounting thanks to the headless design and 118° cone point that bites into materials without protruding
• Effortless installation and removal using the 1/16" hex drive, compatible with standard tools for quick assembly
• Reliable coarse threading (UNC) that resists loosening and allows for faster installation compared to fine threads
• Full regulatory compliance meeting ASME B18.3, ASTM F912, RoHS 3, and REACH for safe, globally accepted usage

Professional Applications & Engineering Value

This 6-32 UNC set screw delivers critical performance in precision assemblies where space constraints and vibration resistance are paramount. The black-oxide alloy steel construction, combined with Rockwell C45 hardness, ensures the fastener withstands shear forces and environmental exposure without compromising integrity. Its headless design and cone point (118° angle) provide a flush, deeply engaged grip on shafts, collars, and gears—effectively preventing axial movement in power transmission systems and machinery components. The coarse UNC thread and Class 3A fit offer superior tolerance control, reducing the risk of cross-threading during high-speed assembly. Ideal for industrial automation, motor mounts, and equipment manufacturing, this set screw solves alignment and slippage challenges while meeting rigorous ASME B18.3 specifications.

Specification Summary & Compliance

This set screw adheres to Class 3A thread fit (UNRC - Unified National Coarse) with a diameter of 0.138" and 1/8" length, manufactured per ASME B18.3 and ASTM F912 standards. The black-oxide surface treatment enhances corrosion protection without dimensional alteration. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures the fastener is free of hazardous substances, making it suitable for international supply chains and environmentally conscious industries.
