The concept is simple enough. Imagine a male thread on a screw or bolt is like a spring wrapped around a smooth bar and a female thread, a spring inserted into a smooth bore. When a thread gets stripped, it’s as if that spring is being removed and in some cases, that’s exactly what it looks like. It’s not uncommon for a stud to pull out of an alloy casting with the aluminium thread still fitting neatly and yes, a little annoyingly, into its spiral grooves, just like a spring.

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.PSG 256 Video: https://d30qymu4o00meq.cloudfront.net/boellhoff/segment/60ad1c6d597e4300b26381728addd462/hls/1634968362087/60ad1c6d597e4300b26381728addd462.m3u8

HELICOIL® – Thread inserts for metals | Böllhoff

The thread insert without tang. You do not need a driver tang to install these thread inserts. Thus, there is no need to break off and remove tangs. The advantages of the HELICOIL® Plus systems are particularly apparent in processing and tools, as they significantly reduce installation times. If done correctly, a HeliCoil is a strong repair and the only real thing to be careful of is that the fresh hole which takes the insert is drilled clean and square. That doesn’t mean to say it can’t be a hand-held job as long as it’s done carefully. The first time I ever did it was to replace a couple of sump bolt threads in an MG TC engine which was still in the car. The threads were in poor shape through old age and, probably, not the greatest quality post-war casting. Fixings on XPAG engines are a weird concoction of metric fine with BSF heads. However from memory, the bolts in question were 1.0mm metric fine and getting HeliCoil kits for them was no problem. I’ve done something similar recently and with equal success on the chassis of my Ford Sierra RS Cosworth and I’ll cover that in the next column.Just like the HELICOIL®Plus, the HELICOIL® Smart is provided with a special thread start to allow easier installation in a holding thread.
