What should the torque be on a bolt?
US Recommended Bolt Torque. † Fine thread figures are for 1″-14. Grade 2, 5, and 8 values are for slightly lubricated bolts.
What should the torque be for grade C lock nuts?
Clamp loads for Grade C lock nuts equal 75% of the bolt proof loads specified for SAE J-429 Grade 8, and ASTM A-354 Grade BD bolts. IFI-100 does not govern lock nuts above 1″. The values shown in the chart are to be used as a mid- range guideline. ** Torque values for 1/4″ and 5/16″ sizes are in inch lb. All other torque values are in foot lb.

What are the torque requirements for bolts?
The required bolt clamping force for a joint is 20000 lbs. The torque required for a 3/4″ dry steel bolt to achieve this tension can be calculated as. T dry = (0.2) (20000 lb) (0.75 in) = 3000 (in lb)
What are torque specifications?
Torque specifications are for dry threads only. The fastener threads should be free of oil, dirt, grit, corrosion, etc. The hardware should turn freely without binding when tightened by hand. It is important NOT to lubricate hardware threads or seats. The friction at which torque is measured against should come from the hardware seats.
What is metric torque?
The metric (SI) unit of torque is the newton metre (Nm). In inch units, torque is usually measured as Lb-Ft (pounds feet) or Lb-In (pounds inch).
What is a torque screw?
Screw Conveyor Torque. Torque is defined as the twisting force exerted by the drive unit on the conveyor screw. Torque is transmitted through the drive shaft of the drive unit to the screw and converted to force to convey the bulk material.
