Hexagon Head Cap Screws(Inch thread)

Hex head cap screws are high-strength fasteners featuring a six-sided head, allowing for secure and precise torque application using tools like ratchets, socket wrenches, or spanners. Distinguished by their washer face under the head and chamfered end, they provide even load distribution and easy installation. TUZ’s Hexagon Head Cap Screws (Inch Thread) meet ANSI/ASME B18.2.1 – 1996 standards, ensuring exceptional quality, reliability, and compatibility for demanding applications.

TUZ’s hex head cap screws are built for strength, durability, and precision in challenging applications. Key features include:


Key Features 

  • Unmatched Durability

          Made from high-quality materials like Alloy Steel SAE 4135, Carbon Steel SAE 1035, and Stainless Steel 304, these screws are built to last. Surface treatments, such as black oxide and GEOMET® coatings, provide excellent corrosion resistance for long-term performance.

  • Superior Strength and Reliability 

          With a strength classification of Grade 8 (39-44 HRC hardness) and Grade 5 (22-34 HRC hardness), these screws offer the tensile strength required for high-stress applications. Their chamfered ends ensure smooth threading, reducing the risk of thread damage during installation.

  • Effortless Installation and Precision 

          The washer face under the hex head evenly distributes axial loads, preventing material damage. The chamfered end facilitates easy alignment and smooth threading, even in tight spaces.

  • Enhanced Torque Application

         The six-sided hex head design allows for even force distribution, enabling higher torque application than screws with recessed heads. This reduces the risk of stripping while ensuring a secure fastening and easy removal when needed, even after prolonged use.

  • Rigorous Quality Assurance 

         Each screw undergoes comprehensive quality control, including hardness and tensile load tests, along with detailed PPAP reports to ensure compliance with specifications and quality standards.

  • Versatile Packaging Solutions 

         TUZ offers flexible packaging options, including bulk, small box, and customized solutions, to meet the specific needs of your projects. Whether for large-scale construction or smaller maintenance tasks, we have the right packaging for your requirements.
