Threaded Studs Both Ends Are Outside The Thread

There is no head, only two ends are outside the thread of a class of fasteners. When connected, it must be screwed into the part with internal screw hole, the other end through the through hole with the parts, and then screw the nut, so that the two parts fastened into a whole. This type of connection is called a stud connection and is a detachable connection. Mainly used for connecting parts of a larger thickness, requiring a compact structure, or because of frequent demolition, should not be used bolted connection occasions.

Category Use Editors

1, bm = 1d studs are generally used for connection between two steel connections; bm = 1.25d and bm = 1.5d studs are generally used for cast iron connections and steel connections The bm = 2d stud is generally used for connection between aluminum alloy connections and steel connections. The former connector has an internally threaded hole and the latter is provided with a through hole.

2, equal length studs at both ends of the thread are required with the nut, washer with two for the hole with the connection.

One end of the welded stud is welded to the surface of the connected member and the other end (threaded end) passes through the connected member of the tape through hole, and then the washer is fitted and the nut is screwed so that the two connectors are connected as a unit.

Screws are more general.

The exact statement should be bolts, screws, and screw caps.

Bolts and screws are round bar objects, engraved with equal spacing thread.

Bolts are flat head cylindrical type; the screw is the front is pointed like a nail.

The bolts must be used with the screw cap, or on objects that have been threaded.

Screws are used in relatively soft or relatively thin objects, when used with their own thread side of the rotation side of the forward drilling.

The threads on the bolts are relatively shallow without the edges; the threads on the screws are sharper and the threads are deeper, facilitating drilling into the objects.

Most bolts and screws require a simple and easy tool - the screwdriver.
