Lead screw nuts

The ability to supply a professionally tapped nut, matched to the thread of the supplied screw is the key to supplying quality linear application products. In many cases screw stock and specialised nut designs are purchased from different sources which can lead to poor fitting of the nut, excessive wear, backlash and low efficiency to the whole linear package.

When you want a more sophisticated nut design the chances are the part has more importance in the workings of the machine. By supplying both items from the one source, Abssac Limited eliminates this area of potential trouble. The designer can also utilise the experience of its engineers to incorporate many features into the nut design in complete confidence.

To date many bespoke nut designs have been supplied, including optical mounts, cams, external threads, mounting holes, pulley grooves, tangs and linear guides to name a few. Lead screw sizes range from 1mm diameter up to 100mm with a wide range of both metric and imperial leads per diameter. Nuts can be manufactured in just about any machine able material including Bronze, steels and advanced plastics such as Delrin, PTFE or Turcite .

We have recently supplied a bespoke nut design for an engraving machine manufacturer who required a Turcite nut design to incorporate a square rigid body, 6 locating holes of differing diameter and a linear guide slot on the traversing head.
