Repair damaged spark plug threads with this spark plug thread chaser
Repair damaged spark plug threads with this spark plug thread chaser

Laser Tools have just introduced a new spark plug service tool designed to get you out of trouble and speed things up — the spark plug thread chaser (part number 7831). Spark plugs can be difficult to remove but also they can be difficult to fit correctly, resulting sometimes in crossed threads or damaged threads. Even if the first couple of threads are damaged, any further tightening of the spark plug will just lead to further damage. 

So if you feel the spark plug is reluctant to screw in cleanly, reach for the thread chaser. It’s designed for 14mm x 1.25 plug threads, 70mm in length and is 3/8" drive. The narrow profile makes it ideal for hard to reach areas.

Coat with grease to catch any metal swarf, then gently run the chaser down the length of the plug thread. It will restore the threads and let you fit the new spark plug. Manufactured from chrome vanadium alloy steel for strength and black phosphate coated for corrosion resistance.

One of these essential service tools to keep handy in the toolbox. Available now from your Laser Tools stockist.
