Basic classification of flange bolts

1, Hex head screw with hole bolt

A split pin hole is formed in the screw through the wire hole, and the machine is loosened by mechanical relaxation.

2, hexagonal head hole bolt

The hinged hole bolts accurately fix the mutual position of the linked parts and can withstand shear and extrusion in the transverse direction.

3, cross recessed hex head bolt

Easy to install and tighten, mainly used for light work and instrumentation with less load

4, square head bolt

The square head has a large size and a large force surface, which facilitates the wrench to catch its head or rely on other parts to stop the rotation. It can also be used in parts with T-slots to adjust the bolt position. Class C square head bolts are often used on rougher structures

The square neck or cymbal has a non-stop effect, and is often used in applications where the surface of the joined parts is required to be flat or smooth.

The ratio of the "support area to the stress area" is larger than that of the ordinary hexagon bolt, so the bolt can withstand higher preload. Pine performance is also good, so it is widely used in automotive engines, heavy machinery and other products. Hexagon head with holes and slotted bolts. When used, the bolts can be mechanically locked for reliable locking.
