Hexagonal screw with partial thread UNC 5/16x2.1/4

Product detailed description

The 5/16 x 2 1/4 inch UNC (Unified National Coarse) hex head partially threaded bolt is designed for applications requiring high strength and reliability. This bolt is grade 5, which corresponds to approximately grade 8.8 in metric standards, and is made of steel. Grade 5 strength provides an optimal combination of tensile strength and fatigue resistance, making it ideal for mechanical joints subject to dynamic loads.

The bolt has a hex head that allows for easy and efficient tightening using standard wrenches or sockets. The partial thread provides better stability and strength in the joint by allowing the smooth part of the shank to transmit shear forces, while the threaded part provides a firm hold. The UNC thread type is characterized by a thicker profile, which provides better resistance to stripping in softer materials.

This screw is manufactured without a surface treatment, which means that it is suitable for applications where additional corrosion protection is not required. It is important to consider the use of a suitable surface treatment or protective agents if the screw is exposed to corrosive conditions. The screw complies with ASME B 18.2.1 and is suitable for use in a variety of industries where a reliable and durable connection according to American standards is required.
