Hexagon bolts are fasteners made up of fingers and screws. The Dapeng bolts are divided into iron bolts and stainless steel bolts according to the material.There are 4.8 class bolts and 8.8 class bolts in iron classification.Stainless steel bolts are made of stainless steel SUS201 bolts, SUS304 bolts, SUS316 bolts.

stainless steel bolts : A class of fasteners consisting of a head and a screw (cylinder with external thread), to be fitted with a nut for fastening two parts with through holes.

This type of connection is called bolt connection.If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Hex Bolts manufacturer: Dapeng

classification

1. According to the force mode of connection, there are ordinary ones and ones with reaming holes. The bolts for reaming holes should match the size of the holes and be used when subjected to transverse forces.

2, according to the shape of the head with hexagonal head, round head, square head, countersunk head, and so on, the general countersunk head is used in the requirements of the joint surface smooth no protruding place, because countersunk head can be screwed into the parts.

In addition, in order to meet the need of locking after installation, there are holes in the head and the rod, which can prevent the bolt from loosening when it is vibrated.

Some of the unthreaded bare rods are to be made thin and are called narrow-waist bolts. They are good for variable force connections.

There are special high-strength bolts on the steel structure. The head will be enlarged. The size also changes.

In addition, there are special USES: T-slot bolts, the most used on the jig, special shape, the head should be cut off on both sides.

There are also special stud welding, one end has a thread, one end can be welded to the parts, the other side directly screw nuts.
