Recoil® wire thread inserts and tooling systems

Recoil’s range of quality wire thread inserts enable you to produce strong, permanent threads in metals and plastics but are particularly useful for creating strong threads in softer materials such as aluminium, titanium and magnesium alloys. Find out here how Recoil inserts work.

Recoil offer a huge range of insert sizes from 2mm diameter up to 100mm and in virtually all thread forms including METRIC, UNC, UNF, BSC, BA, BSP and BSW. We also stock rarer thread forms such as National Pipe Taper (NPT). Our new Tangless® range of inserts is especially effective for engine and electronics applications.

And to install the inserts our ever expanding tooling range is available to ensure that you have the right tool for the job. Whether you are installing only a single insert or 100,000 inserts we have a tool suitable for you. Ranging from simple hand tools to complete pneumatic installation systems, Recoil tooling is simple to use and incredibly effective. Find out more about Recoil tooling systems.

How a Recoil wire thread insert works

Recoil inserts are rolled from high quality stainless steel wire with a diamond shaped cross section, wound to the shape of a spring thread. Once the insert is installed into a tapped hole, it provides a permanent and wear resistant thread in the parent material designed to be stronger than the original thread.

The inserts are greater in diameter than the corresponding tapped hole and compress as they are installed. This allows maximum surface contact area with the tapped thread, safely and permanently anchoring the inserts into place.

The insert’s compensatory action shares the load over the entire bolt and hole, increasing holding or pull out strength. With a Recoil insert in place, load and stress are more evenly distributed.
