Socket Head Bolts


The main function of socket head bolts is to be used in machine parts, die fixturing, and clamping.  They are also known as socket cap screws, because of the cylindrical barrel shape head that contains a hexagonal socket. Socket head bolt dimensions metric are available in a wide range and well known for use with confined space.  Socket button head bolts are specially designed for built-in washers. It ensures that the soft and thin material remains safe from crushing. Socket head bolt manufacturing processes go through the stages from wire rod inspection to thread rolling and plating the finished product. 

Socket head bolts grade 8 is considered to be stronger than lower grades like grade 3 or grade 5. The feature of resistance from rust and corrosion is also available in socket head bolts stainless, and it makes them durable and reliable for a longer duration. Socket head bolts M8 is one of the best products to use for machines with the specialization of bright finish and are even fully thread. 

Socket flat head bolts come with the feature of countersunk and have a flat head at the top. They are resistant to deterioration and even are efficient to deal with severe weather conditions. Socket head cap screw bolt grades show their efficiency and strength. A grade 12.9 cap screw is more efficient than grade 8. 

The socket for the star head bolt has a 6-point star-shaped pattern at the top and requires a star screwdriver to tighten and untighten them.  Socket head bolt grade chart shows the size, dimensions, and body structure of the screw cap. It makes the process of selecting the accurate screw cap easier. In addition to this, the socket head bolt torque chart helps in maintaining the grading system in the Socket head bolt.

Socket head bolt size chart helps in knowing the size of the fastener and people can buy suitable Hex Socket Head Cap Screw for their use. Several companies manufacture Socket Flat Head Bolt with special features and functions.
