Avdel® can offer a range of high performance, robust, ergonomic, hand-held tooling right through to fully automated vibratory bowl-feed equipment. The installation of Avdel® threaded inserts is easily accomplished using the full range of tooling available.

Avdel® pioneered the development of blind threaded inserts in the 1950s for automotive and aerospace applications. Known in the market as 'Nutsert®, they are used extensively in the assembly of white goods, furniture, all types of motor vehicles, electrical components, HVAC equipment, etc.

They offer a quick, reliable and low cost system of inserting high quality, permanent, and load bearing threads. The inserts can be installed rapidly from one side of the work-piece making them ideal for the assembly of boxed or enclosed sections.

Each installed threaded insert provides a securely anchored female thread in the parent material that may be sheet or tubular steel, aluminium extrusion, cast magnesium, moulded plastic or a wide range of composites. The body of the insert is allowed to bulb in a controlled, ductile fashion to create a large 'footprint' on the blindside of the parent material that resists pullout loads. Minimal deformation of the parent material is caused.

How they work:
Generally the insert is threaded onto the mandrel of the tool and then placed into a prepared hole, the mandrel then retracts into the tool which collapses the wall of the sheet, or expands the insert into the parent material. The mandrel then reverses from the threaded insert to complete the installation.
