Socket Head Bolts

The use of a socket head bolt is in areas that experience space constraints. These fasteners were specially designed to work in applications that did not have adequate space to maneuver wrenches or sockets while fastening conventional bolts. Being a special fastening device, the socket for star head bolt is suited to applications involving machine parts, die fixturing, as well as clamping. During the socket head bolt manufacturing process, the producer is able to create several variations amongst these bolts.

For instance, these bolts could be produced with nylon pellets. It is typical for this variation of socket head bolts grade 8 to feature an internal hexagon drive. The Allen head, or what is referred to as the internal hexagon drive will provide an extra locking strength in the form of a small nylon pellet. The application of the nylon pellet to the threads will prevent the eventual loosening of the socket flat head bolt through vibration. Another feature of this nylon pellet bolt is that it features a tall head and can offer high strength. The second variation of these bolts is when the Socket Head Bolts manufacturer in India constructs these bolts with full thread.

This type of bolt is not only a tall-headed one but is also an internally-driven fastener. The fully threaded socket head bolt dimensions metric covers the entire length, thereby making it a high-strength fastener, hence the term. The third variation amongst socket head cap screw bolt grades has a drilled head. This featured hole drilled in the head permits the acceptance of a wire thread as a safety characteristic. In comparison to a Grade 8 hex head cap screw, the bolt is 20% stronger, whereas if compared to a Grade 5 hex cap screw, the socket button head bolt is 50% stronger.
