Key Features & Benefits at a Glance
- Maximum holding power with Class 3A thread fit for secure, vibration-resistant fastening in precision assemblies
- Superior corrosion resistance from black-oxide coating, extending service life in harsh industrial environments
- High-strength durability with Rockwell C45 hardness alloy steel, resisting deformation under heavy loads
- Space-saving headless design allows flush mounting where protruding fasteners are impractical
- Precise torque application via 0.035" hex drive, preventing tool slippage and damage to critical components
- Fine UNF threads provide increased engagement strength for improved load distribution
- Cup tip design creates positive locking action on shafts and collars without marring surfaces
Professional Applications & Engineering Value
Engineered for demanding industrial applications, this 2-64 UNF set screw delivers exceptional performance in precision machinery, automotive assemblies, and electronic enclosures where vibration resistance and reliable positioning are critical. The black-oxide alloy steel construction combined with Class 3A thread fit ensures consistent clamping force while resisting environmental degradation. The headless hex drive configuration enables installation in confined spaces while maintaining maximum torque transmission without compromising component integrity. These fine thread set screws are particularly valuable in applications requiring frequent adjustments or where precise axial positioning of gears, pulleys, and collars is essential for optimal system performance.
Specification Summary & Compliance
This precision set screw features 2-64 UNF fine threads with Class 3A thread fit for superior dimensional accuracy. Manufactured to ASME B18.3 specifications with 0.086" thread diameter and 3/16" length. The component is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
