Key Features & Benefits at a Glance
- Superior corrosion resistance thanks to 316 stainless steel construction, ideal for harsh industrial and marine environments.
- Exceptional mechanical strength with a 70,000 psi tensile strength and Rockwell B70 hardness for reliable performance under high stress.
- Secure and stable fastening ensured by the Class 2A thread fit and coarse UNC thread, providing excellent vibration resistance.
- Easy installation and removal with a standard 3/4" external hex head, compatible with common wrenches and sockets.
- Optimized for partial thread applications where a non-threaded shank is required for precise clamping and alignment.
- Full compliance with major industry standards including ASME B18.2.1, ensuring dimensional accuracy and interchangeability.
- Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting strict regulatory requirements.
Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 316 stainless steel hex head screws solve critical challenges in corrosive or high-strength environments. The partially threaded design allows the unthreaded shank to bear shear loads directly, preventing thread damage and ensuring precise component alignment in machinery, structural frames, and heavy equipment. The coarse UNC thread and external hex drive enable rapid assembly and disassembly, even in low-visibility conditions, reducing maintenance downtime. With 70,000 psi tensile strength and excellent corrosion resistance, they provide long-term reliability in chemical processing, marine, and outdoor installations, minimizing replacement costs and failures.
Specification Summary & Compliance
This 1/2"-13 UNC hex head screw adheres to precise dimensional standards with a Class 2A thread fit and inch system measurements. It is manufactured in compliance with ASME B18.2.1 for consistent quality and interchangeability. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility for global supply chains.
