Metric tools

**SS Camaro UK** · 04-09-2012, 10:48 AM

Hi everybody, just a quick question. Are all the nuts and bolts on LS1 F-bodies sized with the metric system? I have some tools from the system that use fractions of inches, but I can't remember when I last used them so I might as well get rid of them (if they're no use on my Camaro).

A lot are, but things like the lugs, at least mine, are USC.

**pajeff02** · 04-09-2012, 01:02 PM

Lugs are actually metric. I am not aware of any non-metric bolts. I did have some issues with the brake lines as I recall. Nothing seemed to fit real well.

Are the caliper pins 1/2?

I think I'm mixing things up with Jeep, LOL.

Pretty sure if we are thinking of the same bolt it is 13mm, lugs are 19mm but a 3/4 will work. Been doing a lot of wrenching the past week haven't used a standered size yet! Did use a crescent wrench once but I think I set it on mm.......lol

I thought the caliper pins were 12mm.

**KMdef9** · 04-09-2012, 08:44 PM

I'm thinking of my Jeep then.

I only know for a fact that the lcas, the pan hard and all the bolts for center console are all millimeter.

I am one whom believes you can never have enough tools, so I never get rid of tools unless they are broken.

Jeff is right calipar pin bolt's are 12mm..

I agree. As soon as you get rid of em you will need them for something.

everything is metric on these cars.....not sure there are many newer cars left out there with standard bolts on them.

93-97 V8 the engine fasteners were standard,the chassis is all metric and torx.

98-2002 V8 is all metric and torx.

All 93-02 V6 engines used standard fasteners.

Not quite true.. All the upper intake manifold bolts are 10mm.. Same goes for the TB bolts.. Coil pack bolts are 6-point 5.5mm..

Rail bolts are 8mm but 5/16 will work, and 13mm crosses with 1/2..

Fuel tank purge solenoid and thermostat housing bolts are metric aswell as coolant diverter bolts and alt bolts.

The 3800-II is more a fixture of SAE and Metric.

The last time I used my SAE tools was on the 1979 Trans Am I once owned, but I sold that on in 2005 and haven't used them since. I'm only thinking of getting rid of them to make room for more metric tools because that's what most things are in the UK.

I'll have to give it some serious thought.

I was going off the other GM calipars I have removed in the past were 13's because that is always the socket I can never find but always put back...LOL

I wish I had 3 of every size maybe some day!!! You can always learn something new here

It's all good, to this day I think that's still the only bolt I've ever used my 12mm sockets on..

It's an odd ball like a 17mm or 19mm..lol

Can't believe I forgot this one.

Save your 5/8 deep socket.

Anyone who said everything is metric care to redeem themselves by telling the OP what he'll need that for?

Spark plugs... final answer haha. Although I never said it was all metric

Although, 5/8 is the same as 16mm....

Certainly can be used, but....

(5/8in) x (25.4mm/in) = 15.875mm

**Too Fast** · 04-16-2012, 06:07 PM

Yeah. I've done some conversions like that, just to see how close the actual size is.
13mm is slightly bigger than 1/2''
11mm is slightly smaller than 7/16''
