Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit ensuring tight, secure fastening in demanding applications
- Enhanced corrosion resistance from the black-oxide finish, extending service life in various industrial environments
- High-strength durability thanks to alloy steel construction and Rockwell C45 hardness, resisting deformation under load
- Secure, non-slip installation with the 3/32" hex drive, allowing for precise torque application in confined spaces
- Firm gripping action from the cup tip design, preventing component slippage and maintaining positional accuracy
- Reliable fine thread engagement with 10-32 UNF right-hand threads, providing excellent vibration resistance
- Headless, space-saving design ideal for applications where protruding fastener heads are not feasible
Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw delivers exceptional performance in precision assembly and machinery applications where vibration resistance and positional security are critical. The black-oxide alloy steel construction provides excellent durability against wear and mild corrosion, while the Rockwell C45 hardness ensures the screw maintains its integrity under repeated stress. The cup tip design concentrates pressure on a small contact area, creating strong frictional locking that prevents shafts, collars, and gears from rotating or sliding. Combined with the fine thread spacing and 2 1/2" length, this headless screw is engineered for permanent setting applications in automotive, aerospace, and industrial equipment where reliability cannot be compromised.
Specification Summary & Compliance
This set screw features 10-32 UNF fine threads with Class 3A tolerance for high-precision fit, a 3/32" hex drive, and overall length of 2 1/2". It is manufactured in compliance with ASME B18.3 specifications (ASTM F912) and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial supply chains.
