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 through black-oxide coating on alloy steel, extending service life in demanding industrial conditions
- Precise torque transmission via 5/32" hex drive design, preventing tool slippage and ensuring consistent installation
- Exceptional thread engagement with UNF Class 3A fine threads, delivering higher clamping force and reduced loosening risk
- Wide temperature compatibility from -70° to 250°F, ensuring reliable performance across diverse operating environments
- Optimized space utilization through headless construction, ideal for confined assemblies where protruding fasteners are impractical
- Enhanced mechanical strength with Rockwell C45 hardness, providing durable performance under repetitive loading conditions
Professional Applications & Engineering Value
This black-oxide alloy steel set screw addresses critical challenges in precision assemblies requiring permanent positioning. The UNF fine thread configuration with Class 3A tolerance ensures minimal backlash in high-vibration applications like robotic arms, conveyor systems, and precision machinery. The integrated nylon patch thread locker creates permanent resistance to rotational forces, eliminating the need for secondary locking mechanisms. Engineered for industrial set screw applications where thermal cycling is common, the temperature-stable locking compound maintains integrity from sub-zero conditions to elevated temperatures. The headless design enables flush mounting in shafts, collars, and knobs while the hex drive provides positive engagement for precise torque application during installation.
Specification Summary & Compliance
Manufactured to ASME B18.3 and ASTM F912 specifications with UNF Class 3A thread fit for precision dimensional control. The 5/16"-24 thread configuration features fine pitch spacing for enhanced holding power. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global industrial applications.
