Questions & Answers

In order to get the black plug out of the racchet hole, how do you do it?

I had a hard time. Why they placed them in a way that is so strange to me. Almost certainly I used pliers or, more likely, a screw driver to insert it into the rachet / small hole so that the blade faced the plug and then I would take the socket and pound it on the ground with the screw driver. There are a lot of sockets where they do this. I wish you all the best

If so, will a socket or wrench fit the drive end? And if so, what size is the ?

Is it a 3/8 drive for entry into a socket? Any standard socket with a 3/8 chuck should fit without any issues, great for homeowners. I miss those good old days

Can you tell me how long the socket is?

A 2 1/2" total length is measured. Two inches of working depth is required.

This is how the spark plug is held in place What would you recommend rubber insert/magnetic attachment ?

It's an insert made of rubber, with a very firm grip

This is an excellent purchase
5/5

It is in fact accurate to state that the product is described (size). I'm very happy with the quality of this material, and it works really This works perfectly to change spark plugs in my Subaru. I used the magnetic component of the socket to do so. This made the process of replacing the spark plugs from an awkward angle very safe and easy.

Walls with a thick texture
4/5

It does not fit inside small spaces since the walls of the socket are thick.

I love it
5/5

After 5 years, the first one finally broke after heavy use. I bought this one after breaking the first one. In addition to using it to remove back bumpers on F150s at least three times a week, I also use it to repair or replace bumpers on impacts. It's a great value that will last for years to come.

I needed it to do what I needed it to do

My Yamaha 25hp outboard has 18mm plugs and little space available to fit them. I bought this kit to replace inboard spark plugs. Plugs are 18mm and fit in the head well. There was no problem with this socket.
