Professional Applications & Engineering Value
Engineered for demanding applications where corrosion resistance and structural integrity are paramount, these 651 Silicon Bronze hex head screws deliver exceptional performance in marine construction, chemical processing, and coastal infrastructure. The UNC coarse thread design provides rapid installation and superior pull-out resistance, while the external hex drive ensures secure tool engagement even in high-torque applications. The combination of 70,000 psi tensile strength and Rockwell B70 hardness makes these fully threaded screws ideal for critical connections in saltwater environments where stainless steel alternatives might suffer from stress corrosion cracking. Their 5-inch length and 1/2"-13 thread size make them perfect for heavy-duty fastening in boat building, dock construction, and offshore equipment where reliability cannot be compromised.
Specification Summary & Compliance
This 1/2"-13 UNC coarse thread screw features Class 2A thread fit tolerances for precise mating and is manufactured to ASME B18.2.1 specifications. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety. Manufactured in the inch system with fully threaded design and external hex drive configuration for consistent performance across industrial applications.
