• Exceptional holding power thanks to the 90° cone point design that bites securely into mating surfaces
• Precise thread engagement with Class 3A fit ensuring reliable, vibration-resistant fastening in critical applications
• High-strength performance from Rockwell C45 hardened alloy steel, resisting deformation under heavy loads
• Easy installation and removal with 1/8" hex drive, allowing efficient maintenance in confined spaces
• Optimized for industrial use with UNC coarse threads that resist clogging and enable quick assembly
• Regulatory compliance assurance meeting ASME B18.3 specifications for consistent quality and performance

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers exceptional engineering value in industrial applications where vibration resistance and secure positioning are critical. The headless design with hex drive enables flush mounting in confined spaces while maintaining high torque capability. The 90° cone point creates concentrated pressure points that prevent component slippage in shaft collars, gears, and pulley systems. The UNC coarse thread configuration provides rapid installation and superior resistance to debris accumulation in manufacturing environments. Combined with Rockwell C45 hardness, this set screw maintains dimensional stability under repetitive stress cycles, making it ideal for heavy machinery, automated equipment, and power transmission systems requiring reliable component fixation.

Specification Summary & Compliance

This set screw features precision 1/4"-20 UNC coarse threads with Class 3A thread fit for tight tolerance applications. Manufacturing complies with ASME B18.3 specifications ensuring dimensional accuracy and performance reliability. The product meets RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) standards for chemical safety. The black-oxide surface treatment on alloy steel provides enhanced corrosion protection while maintaining the Rockwell C45 hardness rating for optimal strength retention.
