Stainless Steel Toothed Flange Self Locking Lock Bolt

What is Self Lock Bolt ?

Flange type :

According to the different positions of flange bolts, the size of the plate is

different, and there are flat bottom and toothed ones, and the toothed ones play a

non-slip effect.

Flange bolt:

Flange bolt is an integral bolt composed of hexagon head and flange plate (the

gasket under the hexagon is fixed by the hexagon) and the screw (cylinder with

external thread), which needs to be matched with the nut. It is used to fasten the

parts connecting two through holes, so the bolt connection is a detachable connection.

Purpose

Flange bolts are composed of hexagonal head and flange plate, and the "ratio of

support area to stress area" is larger than that of ordinary bolts, so this kind of bolt

can withstand higher preload force and has better anti-loosening performance, so

it is widely used. Used in automotive engines, heavy machinery and other products.
