Sealey Ms157 Double End Long Reach Spark Plug Box Spanner 16/18Mm With L-Bar

Good fit and suited to purpose.Reasonable price and speed of delivery.

The Mountfield HP164 mower uses a petrol engine with a deep set small diameter spark plug. This box spanner fits and enables the annual service to be carried out with the minimum of hassle.

Helps to gain access into awkward locations to unscrew the likes of spark plugs on motorcycle or that, but you have to make sure the space available will allow the access of this tool. This brand is trustworthy and the metal used is strong enough to prevent warping to maintain a good grip on what needs to be loosened or tightened, as the cheap generic versions out there are usually made of metal that can warp due to lower grade metals.

Bought to keep in the motorcycle tool bag and its great because its not too big and the handle is removable. Works like it should. Happy

Definitely value for money.. Highly Recommended 👍

Looks sturdy & well made, time will tell.

Took a while to arrive, but did the job of getting my lawnmower spark plug out and screwing the new one in. As has been mentioned, there is no foam insert to grip a spark plug and stop the length of the spanner harming the ceramic part of the plug. It is just a long box spanner that enables you to reach into an engine and replace spark plugs. I suspect this will not remove vertical spark plugs deep in a cylinder head.

Worked well thin wall for tight space to get spark plugs out nice long reach ideal for my Triumph motorcyclec
