Threaded Inserts and Tooling

Threaded inserts are ideal for creating strong, reusable threads in blind holes, especially in soft, thin, or brittle materials like sheet metal, aluminium, plastics, and composites. Unlike self-tapping screws, threaded inserts do not wear out the parent material and allow for repeated assembly without loss of strength. They provide superior load distribution, which reduces material damage and improves the durability of the joint. Threaded inserts also serve as an effective repair solution for stripped or damaged holes, helping extend the lifespan of critical components.

The best choice depends on your material and torque requirements. Accufast offers several insert styles:

• DHS / DTS (Hex Body): Designed for metal-to-metal and high-torque jobs. The hex shape prevents spin-out and provides strong torque transfer.

• DLS / DKS (Splined Body): Ideal for soft plastics, sheet metals, and thin materials. These collapse into a bubble shape on the blind side, offering excellent pull-out resistance.

• ARS (Prebulbed Body): Best for brittle or delicate materials. The wings distribute stress across a wider area to prevent cracking during installation.

Tool recommendations depend on the job, but Accufast can help you choose the right one for your application. Common options include:

• Airpower 4 / PS400: Pneumatic or hydraulic tools for consistent, high-volume production.

• GO-RN2: A cordless tool for mobile applications that delivers strong pulling force.

• NSK5 Manual Kit: A hand tool for quick, low-volume repairs and maintenance in the field.

Industries that depend on threaded inserts include transportation, commercial manufacturing, rail, HVAC, agriculture, electronics, and general light industry. They are widely used by OEMs and repair teams where joint durability and reliability are critical.
