Professional Applications & Engineering Value

This 1/2"-13 UNC hex head screw delivers critical engineering advantages in demanding industrial environments where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition provides excellent protection against rust and chemical exposure, making it ideal for marine equipment, food processing machinery, and outdoor structures. The partially threaded configuration allows engineers to concentrate clamping force precisely where needed, preventing joint loosening under vibration while the coarse thread pitch ensures rapid installation in structural steel, heavy machinery, and construction applications. With Rockwell B70 hardness and 80,000 PSI tensile strength, this external hex drive fastener maintains integrity under extreme loads, reducing maintenance cycles and replacement costs in critical assembly operations.

Specification Summary & Compliance

This hex head screw features 1/2"-13 UNC coarse threads with Class 2A thread fit tolerance, ensuring consistent mating with standard nuts and tapped holes. The 10-1/2" length with 1-1/2" minimum thread length provides optimal engagement for structural applications. Manufactured to inch system standards with external hex drive and right-hand thread direction. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international requirements for hazardous substance restrictions.
