Design Screws Ltd are the UK licensee for the manufacture of the EJOT range of
Delta-PT®, PT®, Duro-PT® and PT® type DG thread forming screws.

Delta-PT® Screw - developed for use with Thermoplastics materials, the special thread geometry of the screws allows for smaller diameters and/or shorter fasteners to be used, with no loss of torque performance. Resulting in beneficial weight and cost savings over conventional direct fixings.

PT® Screw - for use with Thermoplastics material the PT® Screw has a profiled thread design to assist plastic material flow, which reduces mating component boss bursting forces and develops high stripping torques with low installation torques.

PT® Type DG Screw - developed for use into light alloy metal components giving low installation torques with high clamp loads.

Duro-PT® Screw - design incorporates a “cutting notch” that effectively removes debris that is a common problem with conventional self-tapping screws when used in Thermoset plastic materials, leading to greater stripping torques at low installation torque and reduce bursting forces.

Torx Plus® drive system - dsl are an approved UK manufacturing source for the Acument Torx Plus® and Torx® recess drive system. Torx Plus® drive gives longer tool life and optimal torque transfer which leads to enhanced product reliability, increased productivity and reduced in-place costs on assembly lines in a multitude of industries around the world.
