Professional Applications & Engineering Value
This 7/16"-20 UNF hex head screw delivers exceptional engineering value in demanding applications where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition provides excellent protection against rust and chemical exposure in marine, food processing, and outdoor equipment applications. The UNF fine threading offers superior vibration resistance compared to coarse threads, making it ideal for machinery subjected to constant motion or thermal cycling. With partial threading design, engineers can optimize material usage while maintaining sufficient engagement length for secure fastening. The external hex drive configuration ensures compatibility with standard wrenches and sockets, streamlining assembly processes in manufacturing and maintenance operations.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with 7/16"-20 UNF fine threading and right-hand thread direction. Complies with ASME B18.2.1 dimensional standards for hex head screws. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming restriction of hazardous substances. Features include 3" overall length, 9/32" head height, and 5/8" head width in inch system measurements.
