Professional Applications & Engineering Value

This 15-inch hex head screw delivers critical performance in heavy machinery, structural steel connections, and large-scale equipment assembly where vibration resistance and long-term reliability are paramount. The 18-8 stainless steel composition provides inherent corrosion resistance, reducing maintenance costs in humid or chemical-exposed environments. Its partially threaded design concentrates strength where needed while allowing unthreaded shank sections to act as precision dowels. The 1/2"-13 UNC coarse thread configuration ensures rapid installation and superior pull-out resistance in wood, metal, and composite materials. With 80,000 PSI tensile strength and external hex drive, this fastener withstands extreme mechanical stresses while permitting high-torque installation common in industrial maintenance and construction applications.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 specifications with Class 2A thread fit tolerances ensuring consistent mating with standard nuts. The inch-system screw features 1/2"-13 UNC coarse threads with minimum 1-1/2" threaded length and right-hand direction. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use across international markets. Material certifications confirm Rockwell B70 hardness and mechanical properties meeting industrial fastener standards for critical applications.
