Hot-selling Shear Bolt Joint Connector - BLMT/BLMC Mechanical Shear Bolt Lugs – Waxun
Hot-selling Shear Bolt Joint Connector - BLMT/BLMC Mechanical Shear Bolt Lugs – Waxun Detail:
Overview
Torque terminals are specially designed to handle the connection between wires and equipment.
The unique shear bolt mechanism provides a consistent and reliable stopping point. Compared with traditional crimping hooks, it is super fast and super efficient, and ensures a consistent predetermined shear moment and compression force.
The torsion terminal is made of tin-plated aluminum alloy and has an inner groove-shaped wall surface.
The notable feature is that it can save labor and enhance the electrical and mechanical performance.

Overview
The terminal body is made of a high-tensile tin-plated aluminum alloy. The terminal is suitable for outdoor and indoor applications, and can provide different size specifications.
| Contact torque bolt Made of special aluminum alloy, these contact bolts are hexagonal head double-shear head bolts. These bolts are treated with high-quality lubricant and equipped with a special contact ring. Once the bolt head is sheared off, these contact bolts cannot be removed. Plug-in Special plug-in, put in or take out to adjust the range of applicable conductor. These inserts all have longitudinal stripes and a positioning slot. |

|
The body is made of high-tensile tinned aluminum alloy |
And it can be used with almost every type of conductor and material. |
|
The bolts are made of special aluminum alloy |
Good contact characteristics, can realize the connection between the copper conductor and the aluminum conductor. |
|
Compact design |
Only need a small installation space, especially suitable for large-scale applications. |
|
Tubular spiral design inside the body to improve contact performance |
Excellent electrical performance. |
|
Centering hole and insert |
The conductor oxide layer is split. |
|
Constant torque shear head nut |
The plug-in piece adjusts one size of the connection or terminal suitable for more types of wires. |
|
Lubricated nut |
The inserts help the conductor to be better centered and will not deform the conductor when the bolt is tightened. |
|
Special features of mechanical terminals |
|
|
Long handle |
With extra long length, it can be used as a moisture barrier |
|
Horizontal sealing is suitable |
Suitable for indoor and outdoor applications |
installation
▪ No special tools are required for installation, only a socket wrench is needed for installation;
▪ Each type uses the same reduced length, including the provision of inserts;
▪ Hierarchical fixed torque scissor head nut design to ensure reliable and firm contact;
▪ Each connector or cable lug has a separate installation instruction;
▪ We recommend using a support tool (see attachment) to prevent the conductor from bending.
