Professional Applications & Engineering Value
This 4" steel set screw with 5/16"-18 UNC coarse threads delivers exceptional engineering value in industrial applications where vibration resistance and secure positioning are critical. The square head design with external square drive provides superior torque capability, preventing tool slippage during installation in high-torque scenarios. The Rockwell B80 hardness ensures the screw maintains its structural integrity under heavy loads, while the cup tip creates concentrated pressure points for maximum holding power on shafts, collars, and pulleys. Particularly valuable in machinery assembly, automotive components, and power transmission systems, this right-hand thread set screw offers reliable performance where permanent or semi-permanent fastening solutions are required.
Specification Summary & Compliance
This steel set screw features precise Class 2A thread fit with UNC coarse threads measuring 5/16"-18, ensuring dimensional accuracy and reliable performance. Manufactured in compliance with ASME B18.6.2 specifications for square head set screws, the product meets rigorous industrial standards. The screw is RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, confirming its suitability for use in environmentally regulated applications and industries with strict material restrictions.
