Key Features & Benefits at a Glance
- Permanent vibration resistance with Nylon Patch thread locker that maintains secure fastening in high-stress environments
- Superior corrosion protection from Black-Oxide coating on Alloy Steel, extending service life in harsh industrial conditions
- Precise thread engagement with Class 3A fit ensuring reliable, tight connections for critical assemblies
- High-strength performance backed by Rockwell C45 hardness for durable, long-lasting fastening solutions
- Wide temperature tolerance from -50°F to 250°F, making it suitable for diverse operating environments
- Space-saving design as a headless set screw with hex drive, ideal for compact applications where clearance is limited
- Enhanced grip and alignment with cup point tip that digs into surfaces to prevent component slippage
Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw is engineered to address common industrial challenges like vibration-induced loosening and component misalignment. The Nylon Patch locking technology creates a permanent bond that resists shock and dynamic loads, eliminating the need for additional locking hardware. Made from Black-Oxide Alloy Steel, it offers excellent wear resistance and protection against rust, making it ideal for machinery, automotive, and aerospace applications where reliability is critical. The fine thread spacing and precise Class 3A thread fit ensure minimal backlash and secure fastening in high-precision assemblies, while the headless hex drive design allows for easy installation in confined spaces with a standard 3/32" hex key.
Specification Summary & Compliance
This set screw features 10-32 UNF fine threads with Class 3A fit for high precision and meets ASME B18.3 specifications. It is manufactured from Alloy Steel with Rockwell C45 hardness and includes compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in regulated industries.
