What is the torque of a screw?
Torque is the measurement of twisting force needed to thread the fasteners together.
How is screw torque calculated?
The basic formula T = K x D x P stated earlier takes these factors into account and provides users with a starting point for establishing an initial target tightening torque….What is the Proper Torque to Use on a Given Bolt. by Joe Greenslade.

Is tension the same thing as torque?
“Torque” is simply a measurement of the twisting force required to spin the nut up along the threads of a bolt, whereas “Tension” is the stretch or elongation of a bolt that provides the clamping force of a joint. Torque wrenches provide this tension by the amount of rotational force they apply to the bolt.
How is torque strength measured?
The dynamometer is the most common tool used in the evaluation of torque and power. Dynamometers have the advantages of being very accurate, allowing many types of testing.
What’s the torque on a 6 mm bolt?

What is the difference between a cap screw and a machine screw?
machine screws are a subgroup (of cap screws) and are typically up to 5/16 in diameter, fully threaded, but that distinction is rather blurry – a machine screw with hexagonal recess can be called a cap screw or a machine screw and both names will be correct.
What are the dimensions of a cap screw?
– The diameter range of socket head cap screws is from 0.06 inch to 4 inches according to standard.
What is hex head cap screw?
The hex head cap screw is a common fastener in construction and machine assembly. The screw head is designed to fit a ratchet or spanner torque wrenches allowing you to tighten the screw to your exact specifications.
What is a hex cap screw?
A hex cap screw is a threaded fastener with a hexagonal-shaped head. While the term hex head screw is generally used interchangeably with hex bolt, these two fasteners are actually very different.
