Snap-on 1/2" socket

[wkndfirewood]

Hello All - I recently found this socket while cleaning out. This socket has the words snap-on 86-f stamped on it. I have done some online searches with no information found. So I come to those talented members of the group that may know what this socket is used for

Might be for adjusting the brake cans on semi trucks and trailers. Can't remember what the end of the rod looked like.

Don't know what this particular one is for, but I've seen the type used for shock absorber work. Holding the stem.

Can you post the internal dimensions of the socket? Both directions?

 

[wkndfirewood]

1 1/8" on the flats X 7/16" deep and a 1/4" lip on the inside of the flats 1 3/8" across inside of the socket

 

[wkndfirewood]

2" deep on the inside of socket 1/2 " drive

It could be for adjusting automotive door striker bolts. I have cars that use a similar tool, but the dimensions are different.

It may be under a different number now, and impact. Here is a Snap-on SPS10 shackle pin socket on eBay. The catalog shows two SPS 10 and SPS 11.

So.... I'm probably a little slow on this one but doesn't the F of the 86-F represent thr Snap-On catalog number, which by the way is an early catalog?

I believe it is commonly referred to as a "Double D" One 'D' is forwards and the other is backwards.

Could it be 36F instead of 86F

shackle pin socket for semi truck, The pins have a coarse screw thread and screw into the shackle bushing.

It looks to me that it might fit the Farmall/IHC hydraulic valves, the ones that switch from 1 way to 2 way. gm
