nonstandard connector

1, connected by force, there are common and have reamed hole for. Reamed hole and bolt to fit the size of the hole, when subjected to lateral force used.

2, according to the head of the hexagonal shape of the head, round, square head, countersunk head, and so generally countersunk head with a place in the smooth surface is not required to connect the projections because countersunk head can be screwed to the part where. Circle Parts can also be screwed into the head inside. tightening force square head can be bigger, but the size of a large hexagonal head is the most common.

In addition, to meet the needs of the lock after installation, there is a hole in the head, rod section with holes, these holes can be loose when the bolt is not subject to vibration.

Some did not bolt threaded rod to painstaking, called slender bolts. Bolts favor of this change by force coupling.

There are special high strength bolts on the steel. Head will become bigger and more. Dimensions have changed.

Another special use of: T-shaped slot bolts, jigs and fixtures used in the most special shape, the sides of the head to cut off the bolt, and ground connections for machine fixed, there are a variety of shapes U-shaped. bolt, as described above. Like.

There are special welding studs, threaded one end a head no, parts can be welded on one side and tighten the nut straight.

All kinds of connector and shaft
