Hexagonal screw with partial thread UNC 3/8x5

Product detailed description

The 3/8" x 5" UNC (Unified National Coarse) inch hex head screw with partial thread is designed for applications where durable connections are required according to American standards. This screw falls into the Grade 5 strength class, which corresponds approximately to Class 8.8 according to European standards, and is made of uncoated steel, which means that it is suitable for use in environments where additional corrosion protection is not required.

The screw has a hex head that allows for easy assembly and disassembly using standard tools such as wrenches or sockets. The partial thread ensures a tight connection, while the unthreaded part allows for better load distribution and increases the strength of the connection. This type of thread, UNC, is characterized by a coarser pitch, which increases its resistance to loosening due to vibrations.

The screw complies with the ASME B 18.2.1 standard, which guarantees its dimensional accuracy and quality. Thanks to its properties, it is ideal for use in mechanical engineering, construction and other industrial applications where high strength and reliability of connections are required.
