Thread: Calliper bolts, 12 point socket?

They are FT tho, completely forgot they were 12 pt helping on a friend's very rusty one and I'm surprised I didn't split the very cheap and nasty 12 pointer we could find.

Slightly annoyed if they are triple squares, I've just had a pair of 12 point impact sockets to suit arrive.

the stock 12 pointers will grab the tripple squares just fine.

Looking at the ‘net, it seems that the triple-square is used by several manufacturers, not just LR.

Interesting. Wasn't aware of the difference, as a good quality double hex has always worked just fine, with no damage to the bolt head, OR the socket, and the socket has never "grabbed" the bolt head for me. Pain though, as all my 'Waukee sockets are single hex. I have lots of others, but they are in a different toolbox, which means walking....

They do grip a lot better, than hex shaped fixtures.

classic example of this is the difference between torx and allen heads. Allens almost always chew out when too much torque is required, compared to torx heads of the same size.

I'd be happy to buy a triple-square to suit my L322. I need to find the size. There's not much worse than buggered bolt heads.

They come in kits much like the kit for drain plugs.

If you have the metric bihex sized sockets that fit the size of the tri square is the same but is refered to as (I think) 14mm tri square vs 14mm Bi hex

heres a link to the style of socket that fit the tri squares

It's more that having ordered some special it would have been nice to get the exact ones. I didn't exactly want to go full bore with an impact using a cheap chrome socket (all of my nice ones being 6pt)

Thanks Dave. I did a Google search but only came up with male triple-square, not female. The websites called the male kits "sockets".
