We have over 50 years of unrivaled experience in the design, production and supply of insert technology for plastics, composites and metal alloys for leading moulding and mechanical assembly companies. Our expansive stock range covers many options in steel threaded inserts.

As well as steel threaded inserts, our service also covers:

As well as an extensive variety of brass and steel threaded inserts for plastics, our vast product supply is complemented by a number of tool and accessory options. Our press-fit tools, applicable to the Tappex Multisert range, includes the Tappex Heat Inserter.

This heat inserter is specifically designed to provide efficient and reliable heat insertion of Multiserts in many thermoplastic applications.

We design, manufacture and supply many options in rivet nuts. These rivet nuts are designed with four holes to control the deformation of the body.

This unique feature allows the rivet nut to be used in applications and materials where they may otherwise not be suitable, such as in plastics, composites and wood.

We supply plated steel or stainless steel self tapping inserts from the Trisert-3® range of inserts.

These plated steel or stainless steel self tapping inserts have three cutting features to provide a balanced cutting action as well as reduced installation torque. They are used in critical applications and come in two lengths, regular and long.

We supply a vast selection of grooved pins. Grooved pins offer many benefits and are substantially more reliable when compared to more traditional taper pins, plain pins, keys or locating pins.

Features of grooved pins include:

• Simple hole preparation
• Resistance to shock and vibration
• They are reusable
