How do you know what torque a bolt needs?
How do you know what torque a bolt needs?
The marking check: After tightening the bolt, mark the bolt surface and that of the product or workpiece. Then loosen the bolt. Re-tighten it until the markings re-align. The torque needed to return the bolt to its original position is the torque value of the bolt.
What kind of torque do you need to tighten an imperial bolt?
Example – Required torque for tightening a Imperial bolt. The required bolt clamping force for a joint is 20000 lbs. Example – Required torque for tightening a Metric bolt to proof load. Lubricating the bolt with SAE 30 oil reduces the torque required to achieve the same tension with approximately 40%.
How big should torque be on transmission pans?
Be nice to the bolts and take your time to hand tighten them slowly. It is very easy to cross thread them as I did when I dropped the pan. Coming to torque is should be very less something in the order of 10-15 ft pds. Through the years I’ve dropped a few transmission pans.
When do I need to de-rated my bolt torque?
Also, if the nut material is the limiting factor, the maximum clamping capability (and corresponding bolt torque) of the assembly needs to be de-rated accordingly.
What causes torque difference between tightening and untightening bolts?
Corrosion, seizing, or surface roughness can considerably increase friction and subsequently the untightening torque. With Nord-Lock washers, the difference between the tightening and untightening torque is even more significant.
How much torque does a Buick axle nut have?

What’s the correct torque for an imperial bolt?
Thankfully, standards organizations have assembled the standard tensile strengths for common bolts into easy-to-use standards. SAE J429 governs imperial sizes, while ISO 898 governs metric-size bolts. 1/4 to 3/4in. >3/4 to 1 1/2in. For imperial bolts, grades 5 and 8 are most common.
