Key Features & Benefits at a Glance
- Permanent vibration resistance through nylon patch thread locking, ensuring joints stay secure in high-stress environments
- Superior corrosion protection with black-oxide coating on alloy steel, extending service life in harsh industrial conditions
- Precise thread engagement with Class 3A fit and UNF fine threads, delivering reliable clamping force and reduced loosening risk
- High-temperature performance maintaining locking integrity across -70° to 250° F (-57° to 121° C) operating range
- Optimized drive torque transmission via 3/16" hex drive in headless design, enabling flush installation and space-saving assemblies
- Enhanced mechanical durability with Rockwell C45 hardness, resisting wear and deformation under repeated loading
- Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial applications
Professional Applications & Engineering Value
Engineered for precision machinery and rotating equipment, this nylon patch locking set screw solves critical vibration-induced loosening challenges in power transmission systems and automated assembly lines. The black-oxide alloy steel construction combined with Class 3A UNF fine threads ensures zero backlash in shaft collars, gear hubs, and coupling applications where positional accuracy is paramount. Its headless hex drive design facilitates seamless integration in confined spaces while the temperature-resistant nylon patch maintains consistent locking performance across industrial thermal cycles, eliminating maintenance downtime in material handling and motion control systems.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit and UNF 3/8"-24 fine threading. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The Rockwell C45 hardness and black-oxide surface treatment provide corrosion resistance while maintaining dimensional stability per ASTM F912 requirements.
