- Full threading design enables maximum adjustability and consistent fastening along the entire screw length
- Rockwell C37 hardness ensures excellent wear resistance and durability under repeated use
Professional Applications & Engineering Value
These 10-24 UNC thread socket head cap screws with nylon patch thread locker solve critical vibration-related failure points in industrial machinery, automotive components, and precision equipment. The coarse thread design provides superior resistance to loosening under dynamic loads, while the black-oxide alloy steel construction withstands harsh operating environments. Engineered with Class 3A thread fit, these fasteners deliver precise alignment and consistent clamping force in high-vibration applications where reliability is paramount. The combination of 170,000 psi tensile strength and integrated locking mechanism makes them ideal for permanent assemblies requiring maintenance-free operation and vibration resistance across temperature extremes.
Specification Summary & Compliance
Manufactured to exacting Class 3A thread fit tolerances with UNC coarse threads and full threading along the 1/2" length. Complies with ASME B18.3 specifications and ASTM A574 material standards. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements for industrial use.
