Professional Applications & Engineering Value
This 3/4"-10 UNC set screw delivers exceptional engineering value in demanding industrial environments where vibration resistance and permanent positioning are critical. The steel construction with Rockwell B80 hardness provides the necessary strength to maintain clamping force under extreme conditions, while the cup point design creates deep indentation in shaft materials, preventing rotational slip in pulley systems, gear assemblies, and coupling applications. The coarse thread configuration ensures rapid installation and superior holding power in both soft and hard materials, making it ideal for heavy machinery, automotive components, and manufacturing equipment where reliability cannot be compromised. The external square drive facilitates high-torque application without stripping, saving valuable maintenance time in production settings.
Specification Summary & Compliance
This set screw maintains Class 2A thread fit tolerance per UNC standards, ensuring precise engagement and consistent performance. Manufactured in compliance with ASME B18.6.2 specifications for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial applications without hazardous substance restrictions.
