Torque values

Found this file posted at the yahoo forum when looking for info on a torque spec question. Might be worth making it a sticky somewhere:


Standard Torque table (* = this is a Standard Fastener Torque)
-----------------------
These dimensions are the sizes of the bolt/screw,
NOT the size of the tool to fit the nut/bolt head.

5 mm = 30- 34 in-lb* (> 3/16")
6 mm = 52- 69 in-lb* (< 1/4")
8 mm = 10- 13 ft-lb* (= 5/16")
10 mm = 19- 25 ft-lb* (< 7/16")
12 mm = 33- 45 ft-lb* (< 1/2")
14 mm = 54- 72 ft-lb* (< 9/16")
16 mm = 83-115 ft-lb* (> 5/8")
18 mm = 125-165 ft-lb* (< 3/4")
20 mm = 165-240 ft-lb* (< 13/16")

NOTE: to convert in-lb to ft-lb, divide by 12 (Ex: 60 in-lb = 5 ft-lb)
to convert ft-lb to in-lb, multiply by 12 (Ex: 8 ft-lb = 96 in-lb)
.................................................. ...............................


Most of these torque values are from the Clymer Service Manual

If you find errors or have values not listed, email "doowriter123", and I will update the file.

I don't like using the standard table, but the bottom 3/4 of that post is just what we need...

What about the engine mount bolts? I lost the nut and dampener from the upper rear mount bolt and have just replaced with OEM parts. If I really tighten the nut it seems to compress the dampener so I'm thinking maybe back off a bit and use lock tite. Any ideas?

Where is a good place to get a torque wrench without breaking the bank. Harbor Freight has them advertise cheap but they have bad reviews, so I am hesitant about buying from there. Pep Boys has a good selection but I cannot find any reviews on them.
