Thread-forming in metal

HELICOIL®

There are plenty of options, from simple manual installation tools to standard tools to fully automated complete systems.

Installation mandrel for HELICOIL® Smart – The thread insert with tang that does not have to be broken off.

Thread-forming in metal

Creating high-strength fastenings

Our assembly solutions are designed as fully automatic or semi-automatic workstations. Depending on your requirements, parts can be handled by the operator, a handling system, a rotary indexing system or a transfer system. Take a look at our assembly solutions.

Method and principle

The HELICOIL® installation process

HELICOIL® thread inserts create high-strength, wear-resistant, heat-resistant thread of the highest precision by transferring the forces from flank to flank into the pilot thread. The reduced diameter of the HELICOIL® Plus in the first turn ensures that the thread insert can be installed like a screw.

Installing HELICOIL® thread inserts is easy and cost-effective, because there are only a few basic rules to follow. For efficient assembly, whether for a single application or for high-volume production, we provide a broad range of manual and automated installation tools.

The HELICOIL® system combines conformance to standards with easy installation.

The installation steps in detail

Core hole drilling

You can use a standard twist drill. 
Use a 90° cutter for countersinking and deburring before thread cutting. External diameter of the countersink = DHC + 0.1 mm.

HELICOIL® core hole drilling

Thread cutting

You should use our system’s original HELICOIL® taps to cut the HELICOIL® Plus pilot thread. Use HELICOIL® plug gauges to verify that pilot thread is true-to-gauge.

Thread forming

Use a thread former to quickly and easily produce a chipless internal thread.
