Dimensions are nominal values from the governing standard. Confirm the tolerance class for your application before ordering.
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Torsion Springs conform to DIN 2089. As springs, they are specified by the dimensions in the table below; this page also covers materials, finishes and typical uses.
What Are Torsion Springs?
Torsion Springs are springs defined by DIN 2089. They are selected by wire diameter and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.
Materials & Finishes
Springs are supplied in spring steel, and in stainless (302/316) or phosphor bronze where corrosion or non-magnetic behavior is required. The controlling specification is the wire diameter, the spring rate and the free length; ISO 898-1 property classes do not apply.
Specification Guides
Each size, material and standard of Torsion Springs has its own reference page with the figures for that one configuration.
Torsion Springs are supplied to order. Pricing starts from approximately US$0.20 per piece for standard sizes in spring steel; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.
Custom manufacturing · Made to drawing
Need a torsion springs outside the standard range?
Dimensions, material, finish and form are specified from the drawing — a spring outside the standard range is a variation on existing tooling rather than a new design.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
01
Cold heading
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
02
Thread rolling
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
03
Heat treatment
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
04
Surface treatment
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
