A general purpose torsion spring for industrial machinery, supplied across a wide range of wire sizes and body diameters. This is the part most maintenance and machine build enquiries start from, before the specification narrows to a finish and a leg configuration.
Wire from 0.1 to 8 mm covers everything from an instrument return spring to a heavy machine guard mechanism.
The same geometry can be supplied zinc plated for a workshop or galvanised for an outdoor frame, without changing supplier.
Machine builders rarely have drawings for a spring in a twenty year old machine. A sample is enough to reproduce it.
When ordering a replacement, send the old spring rather than dimensions taken from it. A used spring still carries its wire and coil geometry, and it removes measurement error from the process.
Machines stopped because a spring is obsolete and the original supplier no longer exists
Buying five spring types from five suppliers when one factory covers all of them
Dimensional and load figures are set per order against your drawing or sample, so they are marked TBC rather than filled with catalogue numbers.

Available in Stainless steel, Spring steel, Carbon steel, 65Mn, Music wire, in wire from 0.1-8 mm, with any of our nine surface finishing routes. Geometry, end treatment and finish are all specified per order.
ISO 9001, SGS certificate and RoHS report (stated on the legacy site, certificates pending re-confirmation). Certificate copies are sent on request once re-confirmed.
Against a distributor's stock torsion spring, a made-to-sample part matches your machine exactly rather than approximately, at the cost of a lead time rather than next-day shipping.
Yes. That is one of the most common enquiries we receive. Send the part, or the broken halves of it.
Tell us what you need and we will tell you what is realistic. Replacement quantities are quoted differently from production runs.
Standard production is 7-15 days after order confirmation, with the surface finish included in that window.
Send your drawing, dimensions or a sample. We will confirm the specification and come back with a price and a lead time.
