The inserts by Heli-Coil are a precision formed screw thread coil of stainless steel wire with a diamond shape cross section. These products are the most effective and universally accepted method for thread repair. Designed to quickly and permanently restore stripped, worn, or damaged threads to their original size and condition, the inserts can be used for any part or material including aluminum, magnesium, cast iron, bronze, etc. Maximum clamping action and bolt tension are assured with minimum wrench torque because of the mirror-smooth surface finish of the insert.

Heli-Coil inserts are easy to install. Before the installation the inserts are larger in diameter than the tapped hole. When installing them, the installation tool (not included) reduces the diameter of the leading coil so they can enter the tapped hole. After the installation, each high tensile stainless steel coil expands outward against the tapped hole to permanently anchor the insert. No staking, locking, swaging, or keying in place is required. The products are available in both inch and metric — coarse and fine. Made of premium quality and extremely strong materials, these inserts are all you need to do the job fast and right, while saving your time and money.

With over 65 years of experience in the manufacture of fastening and assembly solutions, Heli-Coil remains at the forefront of the industry and continues to be the leader in the market. With their dedication to exceeding customers' expectations, the company provides a comprehensive array of wire inserts and related assembly tools. All products by Heli-Coil are manufactured using strict quality programs developed to ensure that all products by the company meet the latest industry standards of QS, ISO, TS and AS specifications.

Heli-coil inserts are useful in a variety of situations. Normally I use them in aluminum where they are must haves. Outstanding service and lowest price! Highly recommended!
