Built for strength and precision, TUZ socket head Allen bolts are engineered for industrial reliability.

 

Key Features

  • Precision Torque Application 

          The hexagonal head of the screw provides a secure fit for the Allen key, ensuring accurate and efficient torque transfer. This prevents damage to the screw head and results in a stronger, more reliable fastening.

  • Flexible Threading Options 

          Available in both fully and partially threaded styles to match application requirements for a secure grip and optimal load distribution. Choose UNC (coarse) threading for fast, easy installation in softer materials or UNF (fine) threading for a tighter, more secure hold in harder materials.

  • High Durability & Corrosion Resistance

         Crafted from SCM435 alloy steel or 304 stainless steel, each screw offers high strength and a hardness rating of HRC 39-45, making it ideal for demanding applications. Protective finishes, including black oxide, bright zinc plating, and nickel plating, enhance durability and resist rust and corrosion across various environments.

  • Standards Compliance & Quality Assurance 

         Manufactured to meet ASME B18.3-2002 standards, ensuring precise dimensions and mechanical properties. Comprehensive testing, including salt spray, hardness, and tensile load tests, along with PPAP reports, guarantees performance and provides certification upon request.

  • Convenient Sizing & Packaging 

         Available in sizes from #2 to 3/4" (up to 4" in length) and offered in bulk, small boxes, or custom packaging to meet diverse customer needs.
