APPLICATION IS INTRODUCED


Double-end stud is a cylindrical fastener which is threaded at either end.Widely used in electric power, chemical industry, oil refining, valves, railways, Bridges, steel structures, auto parts, machinery, boiler steel structures, tower, long span steel structures and large buildings.

The diameter, length and quantity of the studs shall meet the requirements. The type and material of the studs shall be determined by grade.Commonly used double-head bolt has two kinds (also known as full thread stud), thread is divided into two kinds of coarse tooth and fine tooth, coarse tooth ordinary thread with M and nominal diameter, fine tooth ordinary thread with M and nominal diameter × pitch.The standard for fasteners stipulates that the bolts of M36 shall use coarse thread, and the diameters of M36 and above shall adopt fine thread and the pitch shall be 3.

Bm =1d double-headed stud is generally used for the connection between two steel connectors;Bm =1.25d and bm=1.5d double-ended studs are generally used for the connection between cast iron jointed pieces and steel jointed pieces;Bm =2d double-ended stud is generally used for the connection between aluminum alloy connector and steel connector.The former connector has an internal threaded hole, and the latter connector has an through hole.The threads at both ends of the double-end studs of equal length should be matched with nuts and washers, which are used for connecting two pieces with through-holes.

Weld one end of the stud on the surface of the connector, and the other end (threaded end) through the connector with a through hole, and then cover the washer and screw the nut, so that the two connectors are connected into a whole.
