Material specifications in all our products are chosen to ensure the quality of the product over it's entire life cycle. We manufacture our washers from a trapezoidal shaped high carbon silicon manganese spring steel.

Trapezoidal Wire Range

Why trapezoidal wire?
The trapezoidal shape refers to the profile of the wire before it is wound into a washer. Once the wire is wound the profile becomes parallel ie. the top and bottom faces become parallel and the inside and outside faces remain parallel. Wire that does not start off trapezoidal before winding will result in a spring washer with a wire section that does not have parallel sides as is shown in the second example.

Standard Range

We are now offering a new range that we believe are very competitively priced that will enhance your purchasing options and will add significantly to the wide range of washers currently manufactured by us. Although not manufactured by us they have passed all the required tests to ensure their quality so you can be sure you are still getting a spring washer that will last. Like most spring washers on the market today they are not manufactured from trapezoidal wire but may still satisfy your requirements of a spring washer.  We will continue to manufacture our own high quality washers as we have done for the past 40 years.

Finish available is zinc plated.

Heat Treatment

Heat treatment  involves hardening the spring washer by means of heating it to a required temperature and quenching it in a mineral based quenching oil. The spring washer is then tempered by re-heating to a pre-determined temperature and held for a set period to achieve the required mechanical properties.
