Professional Applications & Engineering Value
This 5/8"-11 UNC hex head screw delivers exceptional performance in demanding industrial settings where corrosion resistance and mechanical integrity are critical. The 316 Stainless Steel composition provides superior protection against chloride-induced stress corrosion cracking, making it ideal for chemical processing, marine equipment, and food processing applications. The coarse thread design ensures rapid assembly and superior holding power in softer materials, while the partial threading concentrates strength where needed most. With 4" length and external hex drive, this fastener offers reliable performance in structural connections, machinery assembly, and heavy equipment maintenance where vibration resistance and long-term durability are essential requirements.
Specification Summary & Compliance
Manufactured to precise Class 2A thread tolerances with UNC coarse thread profile (5/8"-11) and right-hand threading. 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. Inch system measurements include 4" overall length, 15/16" head width, and 25/64" head height. Threading is partially threaded with minimum 1½" thread length.
