Where can I find torque for a bolt?
Where can I find torque for a bolt?
Proof load, stress area, yield strength, and other data is based on IFI 7th Edition (2003) Technical Data N-68, SAE J429, ASTM A307, A325, A354, A449, and A490. These torque calculations are estimates and are only offered as a guide.
What are the torque specifications for a car?
The specified amount will normally be in 30° increments. Turns of 120° or 180° are preferred. Turns of 120° or 180° are easily measured by the points of the hex head of the fastener. Lubrication may be specified in order to reduce the effort that is required for the final turn.

What happens when the torque is too much?
Too much tension on the bolt will cause the bolt to be stretched beyond the point of yield. The bolt will be permanently stretched. The bolt will loosen the grip on the parts that are being fastened. If the bolt is tightened again, the bolt will break. Do not reuse bolts that have been permanently stretched.
What does the initial torque do on a fastener?
There is an initial torque and an additional turn. The initial torque is required to bring all parts of the joint into contact. The additional turn provides the desired clamping force. Ensure that all fasteners have been torqued before you perform the additional turns. Turn the fastener according to the specified amount.
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%.
What are the torques of mild steel bolts?
Typical values for K with mild-steel bolts in range 1/4″ to 1″: Note! – be aware that this is a rough calculation where the screw pitch is not included. Typical Metric and Imperial bolt torques are indicated in the links below:
What is the torque of a lubricated bolt?
F – axial bolt force or load (N, lb) torque reduction due to lubrication (%) Note that standard dry torques are normally calculated to produce a tensile stress – or axial force or clamp load – in the bolt that equals to 70% of minimum tensile strength or 75% of proof strength.
Proof load, stress area, yield strength, and other data is based on IFI 7th Edition (2003) Technical Data N-68, SAE J429, ASTM A307, A325, A354, A449, and A490. These torque calculations are estimates and are only offered as a guide.
