• Regulatory compliance assurance meeting ASME B18.6.2 specifications for quality and performance standards
• Environmental responsibility through RoHS 3 and REACH compliance for safe use in regulated industries

Professional Applications & Engineering Value

This 1"-8 UNC set screw delivers critical engineering solutions for industrial applications requiring secure, permanent fastening. The steel construction with Rockwell B80 hardness provides optimal strength-to-toughness balance, resisting deformation under heavy loads. The coarse thread design with Class 2A thread fit ensures rapid installation while maintaining precise tolerances in inch-system machinery. The cup point creates concentrated contact pressure, digging into shaft materials to prevent rotational slippage in power transmission systems. The square head with external square drive accommodates standard industrial tools, facilitating secure installation in confined spaces. These features make it ideal for permanent positioning of components on shafts, axles, and collars in manufacturing equipment, automotive systems, and heavy machinery where vibration resistance is paramount.

Specification Summary & Compliance

This set screw features precise Class 2A thread fit with 1"-8 UNC coarse threads and right-hand thread direction, manufactured to ASME B18.6.2 specifications. The inch-system measurement includes 5" length, 1" thread diameter, and square head dimensions of 25/32" height and 1" width. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for regulated industrial applications worldwide.
