• Reliable thread engagement with UNC coarse threads and Class 2A fit ensuring consistent performance and easy assembly
• Corrosion-resistant surface protection from black-oxide finish that extends component life in various industrial environments
• Reduced point loading through 0.625" diameter swivel tip that distributes pressure evenly across contacted surfaces
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for use in regulated industries and global markets

Professional Applications & Engineering Value

This heavy-duty set screw addresses critical engineering challenges in industrial machinery, power transmission systems, and precision equipment where vibration resistance and permanent positioning are paramount. The black-oxide alloy steel construction combined with Rockwell C45 hardness provides exceptional strength-to-weight ratio, resisting deformation under extreme loads. The permanent swivel tip with 7.5° maximum angle compensates for minor shaft misalignments while maintaining constant pressure distribution, preventing fretting and surface damage to expensive components. The headless hex drive design allows flush mounting in confined spaces while the UNC coarse threads ensure rapid installation and superior resistance to loosening in high-vibration environments common in manufacturing, automotive, and heavy equipment applications.

Specification Summary & Compliance

This set screw features precision 3/4"-10 UNC coarse threads with Class 2A thread fit per ASME B1.1 standards, ensuring consistent dimensional accuracy and reliable performance. The 2-1/2" length and 3/8" hex drive conform to industrial specifications for set screw applications. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(a)-I for lead as an alloying element in steel and REACH (EC 1907/2006) compliance, meeting current environmental regulations for industrial components.
