Over 70 Years of Precision Engineering Expertise

In 1936, aircraft designer Sir Oliver Simmonds company produced its first collection of aerospace nuts and accessories. Forty years later, Simmonds permanently indented its name on the fastening world by inventing and manufacturing the first ever range of nylon ring self-locking nuts - The Nylstop.

The Nylstop now forms part of our standard range of self-locking nuts. More.

In recent years, Simmonds has continued to develop this expertise and capability in high specification female thread fastener solutions which enables us to make high precision bespoke nuts to meet the specific quality, performance and cost requirements of our customers. More.

Following large scale investment, we have evolved our capability to include production of cold forged specials and high precision screw machined parts in steel, stainless steel, aluminium alloys and Ni alloys. This enables us to provide complex and innovative solutions to a range of clients across Europe, predominantly in the automotive industry. More.
