Key Features & Benefits at a Glance
- Secure Component Positioning: Nylon 6/6 plastic tip prevents surface damage and loosening under vibration, maintaining precise alignment in assemblies.
- Exceptional Durability: Black-oxide finish on alloy steel provides corrosion resistance, extending service life in harsh industrial environments.
- High Thread Precision: Class 3A fit ensures tight, reliable engagement with mating parts, reducing the risk of stripping or backlash.
- Wide Temperature Tolerance: Nylon tip operates effectively from -50° to 250° F, suitable for applications with thermal cycling.
- Optimized Torque Transmission: 5/64" hex drive allows for high installation torque without cam-out, ensuring consistent clamping force.
- Coarse Thread Advantage: UNC thread design enables quick assembly and disassembly, improving maintenance efficiency.
- Space-Saving Design: Headless construction minimizes protrusion, ideal for compact machinery and rotating components.
Professional Applications & Engineering Value
This 8-32 UNC set screw delivers critical engineering solutions where vibration resistance and component security are paramount. The black-oxide alloy steel construction, hardened to Rockwell C28, withstands high shear loads in pulleys, gears, and couplings. Its green nylon tip acts as a self-locking element, eliminating the need for separate locking washers in right-hand thread applications. The coarse thread spacing ensures rapid installation on production lines while the hex drive accommodates standard tools for maintenance. Ideal for CNC machinery, automotive assemblies, and conveyor systems, it prevents positional drift without marring shaft surfaces.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision tolerance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Thread specifications: 8-32 UNC coarse thread, 0.164" diameter, 3/8" length. Material certification includes alloy steel with black-oxide surface treatment and nylon 6/6 plastic tip meeting industrial temperature ranges.
