S-95235A527 10-32 x 3/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior vibration resistance with nylon patch locking that maintains integrity up to 250°F, preventing loosening in high-stress applications
• Enhanced torque transmission via 3/32" hex drive, allowing secure installation without head protrusion in confined spaces
• Precise thread engagement with Class 3A external thread fit and UNF fine spacing for reliable fastening in critical assemblies
• Extended tip design (0.049" length) ensures deeper material penetration and improved grip strength on shafts and components
• Exceptional durability from alloy steel construction with Rockwell C45 hardness, resisting wear and deformation under load
• Broad industrial compliance meeting ASME B18.3 specifications, RoHS 3, and REACH for global quality assurance
• Optimized for right-hand threading with consistent 10-32 UNF dimensions, facilitating quick assembly in standard applications

Professional Applications & Engineering Value

This 10-32 UNF alloy steel set screw delivers critical performance in precision industrial assemblies where vibration resistance and positional accuracy are paramount. The nylon patch locking mechanism effectively counters rotational forces in motors, pulleys, and gear systems, eliminating the need for secondary retention methods. Its extended tip design penetrates deeper into mating components, distributing clamping force evenly to prevent slippage in shaft collars and couplings. Manufactured to Class 3A thread tolerances with fine thread spacing, it ensures zero backlash in high-speed equipment while the headless construction and hex drive enable flush mounting in space-constrained environments. Engineered for industrial reliability, this fastener maintains consistent performance across mechanical systems subject to thermal cycling and dynamic loads.

Specification Summary & Compliance

This set screw features Class 3A external thread fit with 10-32 UNF fine threads and precise dimensional control including tip length (0.049" ±0.008") and diameter (0.127" ±0.007"). Manufactured from alloy steel hardened to Rockwell C45, it conforms to ASME B18.3 specifications where applicable. The component is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental regulations for industrial use.
