What is a long bolt?

A long-bolt or through-bolt engine is an internal combustion piston engine where, following usual practice, the cylinder head is held down by bolts or studs. Conventionally the cylinder head is bolted to the cylinder block and the crankshaft main bearings are in turn bolted to the crankcase by separate bolts.

What is M in bolt size?

The letter ‘M’ indicates that this bolt uses a metric thread. The number ‘8’ refers to the nominal diameter of the bolt shaft in millimeters. The number 1.0 is the thread pitch of the bolt, which is the distance between threads, in millimeters. And the final figure, 20, is the length in millimeters.

What are bolt grades?

The grade of a bolt determines the maximum amount of stress (tensile strength) that the bolt can handle. Tensile strength is the amount of pull the bolt can withstand before breaking. The SAE marking system uses raised dashes on the bolt head to indicate strength.

How is bolt torque required?

DETERMINING TORQUE The general equation for bolt load based on applied torque is T = KFiDb where K = torque coefficient. K is a function of the coefficients of friction and collar friction in the joint, and these are based on variables such as surface finish, coatings, and so on.

How many threads are in a inch?

In the inch series, it is the number of complete threads per inch (if you need to know the pitch of an inch fastener, use the chart below or divide 1 by the number of threads per inch)….Table 1.

Threads per Inch Pitch (inches) Pitch (mm)
80 0.0125 0.318
72 0.0139 0.353
56 0.0179 0.454
