Professional Applications & Engineering Value
This 3/4"-10 UNC steel set screw delivers critical performance in demanding industrial environments where vibration resistance and permanent positioning are paramount. The coarse thread configuration provides superior holding strength compared to fine threads, making it ideal for heavy machinery, automotive assemblies, and construction equipment where components must remain securely fixed. The square head with external square drive allows for high-torque installation without cam-out issues common with Phillips or slotted drives. Engineered with Rockwell B80 hardness, this fastener maintains its structural integrity through repeated maintenance cycles, while the cup tip creates positive engagement on shafts and collars without damaging surfaces. The Class 2A thread fit ensures consistent performance across production runs, reducing assembly time and improving manufacturing efficiency.
Specification Summary & Compliance
This set screw features 3/4"-10 UNC coarse threads with Class 2A tolerance for precise fitment in industrial applications. Manufactured to ASME B18.6.2 specifications ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial markets with strict chemical substance restrictions.
