Fast Thread Bolting System

Plastic socket sizes are available in:
M20 x 100, M20 x 120, M20 x 130, M20 x 135, M24 x 100, M24 x 110, , M24 x 120, M24 x 135, M24 x 140, M24 x 150, M24 x 160.

The large thread design on the socket allows the bolt to be inserted 4-5 times faster than traditional metric thread. The design of the threads utilises the strength of the concrete (as the load is transmitted throught the concrete) therefore not relying on the strength of the plastic.

Bolts are available in any length, grade, and finish to suit customer requirements. If you have specific requirements, please contact us now to discuss how we can help you.
