Key Features & Benefits at a Glance
- Exceptional corrosion resistance with black-oxide coating, extending service life in demanding industrial environments
- Superior thread engagement with Class 3A fit ensuring precise, vibration-resistant fastening in critical assemblies
- Maximum holding power through 90° cone point design that bites deeply into mating surfaces
- Enhanced durability from Rockwell C45 hardened alloy steel construction resisting deformation under load
- Space-saving headless design allowing flush installation where clearance is limited
- Secure drive engagement with precision hex drive (0.050") preventing tool slippage during installation
- Reliable performance meeting ASME B18.3 specifications for consistent quality and dimensional accuracy
Professional Applications & Engineering Value
This 4-40 UNC set screw delivers critical engineering solutions for precision assemblies requiring secure component positioning. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the Rockwell C45 hardness needed to withstand rotational forces and vibration. The 90° cone point creates permanent seating marks in shafts and collars, preventing axial movement in power transmission systems, motor assemblies, and precision machinery. The headless design with hex drive enables installation in confined spaces while the Class 3A thread fit ensures precise engagement in tapped holes, making these set screws ideal for aerospace components, medical devices, and industrial equipment where reliability is paramount.
Specification Summary & Compliance
Manufactured to exact ASME B18.3 specifications with UNC coarse threads (4-40) and precision Class 3A thread fit for superior engagement. The 7/16" length and 0.050" hex drive maintain dimensional consistency across production batches. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications.
