Professional Applications & Engineering Value
This Black-Oxide Alloy Steel set screw delivers exceptional performance in demanding industrial environments where vibration loosening compromises assembly integrity. The permanent Nylon Patch thread locker provides reliable locking without requiring additional adhesives, maintaining secure fastening across temperature extremes from -70° to 250°F. The UNC coarse threading with Class 3A precision ensures quick installation and superior resistance to cross-threading in high-volume production settings. The headless hex drive design allows for flush mounting in confined spaces while providing ample torque transmission. Ideal for securing collars, gears, and pulleys on shafts in machinery, automotive, and manufacturing equipment where vibration resistance and long-term reliability are critical.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 and ASTM F912 standards with UNC Class 3A thread fit for precision engagement. The 5/16"-18 coarse thread configuration provides optimal holding power in various materials. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for international industrial applications. The Rockwell C45 hardness rating guarantees consistent performance under mechanical stress.
