Threaded Inserts - Customised Designs

We can design and manufacture threaded inserts with a wide variety of forms and finishes to meet your unique assembly requirements. Shown below are just a few examples of our customised insert capabilities. If you have a special requirement which you would like to discuss, please contact your local Avdel representative.

Flange Diameter

Greater diameter increases push-out force and hole reinforcement in soft and thin gauge metals.

Flange Thickness

Thicker flange acts as a spacer and provides a slight increase in push-out force.

Nut Length

Greater length acts as a blind side spacer and increases thread strength.

Body Diameter

Greater body diameter increases thread strength, torque-to-turn and push-out force.

Particularly suitable where the designer wishes to retain a large hole size for a small thread.

Grip Range

Increase in grip is required to accommodate thick wall constructions such as those using aluminium, magnesium, plastics and composites.

Special Cold Formed Products

In high volumes, these can offer significant cost savings compared to equivalent machined components.

Designs possible to very high tolerances for use with your own tooling.


Special finishes can improve corrosion resistance, appearance and colour match with parent materials.

Surface Hardening

Treatments such as nitriding increase thread torque strength.

Closed Ends and Underhead Seals

Provides maximum protection against the ingress of moisture and dirt.

Thread Forms

We can offer a wide range of metric and imperial thread forms to suit your application, including UNC, UNF, BSW, BSF, BA and fine series metric threads.

Example of customised design

Custom High Strength Hexsert®

Special geometry insert provides combination of M8 female thread and a location pin on a hydroformed steel cross car beam.
