Hexagonal screw with partial thread UNC 5/16x3.1/2

Product detailed description

The 5/16 x 3 1/2 inch UNC (Unified National Coarse) hex head partial thread bolt is designed for use in structures requiring high strength and reliability. This bolt is Grade 5, which corresponds approximately to Grade 8.8 according to European standards, and is made of uncoated steel.

The bolt is designed according to ASME B 18.2.1, which defines dimensions and tolerances for hex head partial thread bolts. The hex head allows for easy assembly using a standard wrench, which is advantageous in applications where quick and efficient assembly is required.

The partial thread provides better tensile strength and is suitable for applications where higher mechanical loads need to be transmitted. The UNC thread is thicker, which increases resistance to loosening due to vibration and is commonly used in American structures.

This screw is ideal for use in mechanical engineering, the automotive industry and other areas where reliable and durable connections are required. It is important to consider that the screw is supplied without surface treatment, which may affect its corrosion resistance in aggressive environments.
