Key Features & Benefits at a Glance
- Maximum holding power with Class 3A thread fit for secure, vibration-resistant fastening in demanding applications
- Enhanced corrosion resistance from black-oxide coating on alloy steel, extending service life in industrial environments
- Precise component positioning using the 90° cone point that bites into surfaces without requiring drilled holes
- Superior strength and durability with Rockwell C45 hardness, maintaining thread integrity under repeated use
- Space-saving headless design for applications where clearance is limited and flush mounting is essential
- Easy installation and removal with 1/16" hex drive that provides reliable torque transfer without stripping
- Fine UNF thread engagement for improved load distribution and reduced loosening in precision assemblies
Professional Applications & Engineering Value
These 6-40 UNF set screws deliver exceptional engineering value in applications requiring precise component alignment and reliable torque transmission. The black-oxide alloy steel construction provides superior corrosion protection while maintaining the mechanical strength needed for industrial environments. The 90° cone point design creates positive engagement with shaft surfaces, preventing slippage in power transmission systems, coupling assemblies, and precision machinery. With Class 3A thread fit and fine UNF threads, these headless fasteners ensure minimal backlash in adjustable mechanisms while the hex drive configuration allows for consistent torque application during installation and maintenance cycles. Ideal for aerospace components, automotive systems, and manufacturing equipment where vibration resistance and positional accuracy are critical.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision and UNF fine thread profile. The 6-40 thread size features 0.138" diameter with right-hand thread direction. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The Rockwell C45 hardness rating guarantees consistent performance under mechanical stress while maintaining dimensional stability.
