Hexagonal screw with partial thread UNC 3/8x4.1/2

Product detailed description

The UNC (Unified National Coarse) inch hex head screw with a partial thread, 3/8" x 4.1/2" in size, is designed for applications requiring a reliable and strong mechanical connection according to American standards. This screw is made of steel and falls into the Grade 5 strength class, which corresponds approximately to Grade 8.8 according to European standards.

The Grade 5 strength class ensures high resistance to mechanical stress, which makes this screw suitable for medium-duty applications where higher tensile and shear strength is required. The screw is uncoated, which means that it is not protected against corrosion, and is therefore particularly suitable for use in dry or indoor environments where it is not exposed to aggressive chemicals or moisture.

The hex head allows for easy assembly and disassembly using standard tools such as wrenches or sockets. The partial thread provides a combination of strength and flexibility, allowing for a secure fit while reducing the risk of damage to the material the screw is fastened to.

This screw complies with ASME B 18.2.1, ensuring dimensional accuracy and quality of workmanship. It is ideal for use in engineering, automotive and other applications where reliable and durable mechanical connections are required.
