Professional Applications & Engineering Value

This M24 alloy steel set screw addresses critical challenges in heavy-duty mechanical systems where vibration resistance and positional accuracy are paramount. The headless design with hex drive enables flush mounting in pulleys, gears, and collars while permitting substantial clamping force through the 12mm drive. Engineers benefit from the Class 6g thread tolerance which maintains consistent preload across repeated disassembly cycles, preventing joint failure in conveyor systems, industrial machinery, and precision equipment. The ball tip configuration minimizes surface marring on shafts and rotating components while providing positive locking action. Manufactured from alloy steel with Rockwell C39 hardness, this metric set screw withstands shock loads and cyclic stresses in manufacturing, automotive, and heavy equipment applications where coarse thread pitch ensures rapid installation and removal during maintenance operations.

Specification Summary & Compliance

This set screw maintains metric thread specifications with M24 diameter, 3mm coarse pitch, and Class 6g thread fit per ISO standards. The right-hand thread direction and 84.7mm length provide standardized dimensional accuracy. Manufacturing complies with RoHS 3 (2015/863/EU) regulations under exemption 6(a) for lead as steel alloying element. The ball tip features 18mm diameter matching the alloy steel composition of the main body for consistent mechanical properties throughout the fastener.
