Key Features & Benefits at a Glance
- Superior corrosion resistance with Black-Oxide finish on Alloy Steel, extending service life in demanding environments
- Exceptional holding power from the 90° cone point design that bites into surfaces for secure, vibration-resistant fastening
- Precise thread engagement with Class 3A fit ensuring reliable performance and reduced risk of cross-threading in assembly
- High-strength durability backed by Rockwell C45 hardness, resisting wear and deformation under heavy loads
- Easy installation in confined spaces using the compact 1/16" hex drive and headless design
- Optimized for quick assembly with coarse UNC threads that allow faster installation compared to fine threads
- Broad industry compliance meeting ASME B18.3 standards for consistent quality and dimensional accuracy
Professional Applications & Engineering Value
This 5-40 UNC set screw delivers critical engineering value in applications where space constraints and vibration resistance are paramount. The Black-Oxide Alloy Steel construction provides enhanced corrosion protection for industrial environments, while the 90° cone point creates permanent seating in shafts, collars, and pulleys—preventing slippage in high-torque scenarios. With Class 3A thread fit precision, it ensures consistent clamping force in precision machinery, automotive components, and production equipment. The headless design and 1/16" hex drive facilitate installation in recessed areas, making it ideal for assemblies requiring flush mounting and reliable set screw performance under dynamic loads.
Specification Summary & Compliance
This set screw maintains Class 3A thread fit per UNC standards with coarse thread spacing for optimal engagement. Manufacturing follows ASME B18.3 specifications for dimensional accuracy, including 0.125" thread diameter and 1/4" length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence for global industrial use.
