[cbracer]

and if so for what?

 

[fordmw]

Ford disc brakes is the only thing i can remember using one on.

Ditto. That size is used in oddball ****.


Why do you ask?

 

[Dust]

Chrysler disc brakes as well. I think the front brakes on RS minivans, specifically.

80's BMW brake disc caliper bolts

 

[kab00m]

Volvo brakes if I remember correctly.

 

[shurik06_83]

vw/audi mostly 6mm hex but the odd time they will drop in a 7 to keep u on ur toes

VW caliper pins, I think. Anyway I didn't have one, and ground down a bigger one to fit.

hose clamps for the intake and exhaust on Volvo and Mack trucks.

80's BMW brake disc caliper bolts

The BMW E39 of my dad (1999) still has 7mm... and I think my E46 (2001) too

 

[franzdom]

2003 BMW e46 brake pins, also I believe Bilstein struts on our Volvo & BMW. Due to low clearance in the rear brakes and needing to go through pass through sockets in the struts I have just about every kind of 7mm hex socket.

front brakes on a dodge minivan;
another oddball is 9mm front brakes on a 09 expedition

Guess I screwed up and asked if anyone used a "7mm hex" when I should have asked "7mm hex BIT" ..... Trying to decide if I need one in my hex bit set.

I just assume you meant bit socket when you asked, as doing brake jobs or removing hefty fasteners with a "L" type allen hex key is not ideal nor recommended.

The best metric hex bit sets should have everything from 2 (and 2.5) up to 10 minimum (or bigger if doing major maintence or have a vehicle that takes teh big hex bits for oil filter cartridges and the like.)

It is always a good idea to use a torque wrench when torquing brake caliper bolts, thus the L style wrench is not an option.

Older Campy crank arms bolts were 7mm. (bicycle)

they made a special tool so you could use any 7mm hex with a peanut butter wrench
I happen to have it.

 

[4x4gearhead]

A lot of grease fittings I run into are 7mm or even 9mm, made me say "wtf?" the first few times.

 

[Reality Sucks]

Ive also run into a few dodge truck caliper bolts aswell..

 

[mn700vforce]

I have used a 7mm hex socket on my front brake caliper pin bolts on my ford escape

 

[PinkLinc]

My 2002 MINI S disc brake caliper bolts. I'm sensing a theme here...

 

[JDS968]

Jaguar floating caliper slides.

 

[admranger]

As mentioned earlier, everything from the '80's on BMW brake caliper guide bolts are 7mm (though I haven't checked the ones on the E90M3 yet...).

I have several 7mm 'allen' head sockets just because of this.

That's interesting. Can you post a picture of that tool? My old Campy C-Record crankset required a 7mm hex for removal. Then in the mid90s, they conformed to the standard and are now using 8mm crank bolt extractors. Good Luck!

Calipers on 80s Porsches if memory serves me correct.

7mm allen key holder, can be used inside a 15mm traditional crank bolt wrench:

with a 7mm SO hex socket in it:

a blurry pic of the Campagnolo pin tool needed to remove the 7mm crank bolts from the crankset, they used reverse threads by the way

A reverse threaded Campagnolo crank puller to use in case you removed the hex style and use a traditional 15mm crank bolt instead, note both parts are LH threaded not just the engagement part, these guys were definitely OCD:

Another favorite of mine from that era, the C-Record hub dust cap remover

 

[bfd]

Very nice! You have a nice set of Campy tools! I've never seen that allen key holder, but like that you use a SO 7mm hex socket. The left hand thread crank puller is a very nice tool. I have the normal "righty" version. I also had that hub puller, but sold it when I gave away my C-Record hub rear wheel.

I agree that Campy tools are OCD - my favorite is Campy cone wrenches - simply sublime. Good Luck!
