What is the difference between a325 and Grade 8 bolts?

A325 bolts are typically manufactured from a medium carbon steel (although they can be made from an alloy) while SAE grade 8 bolts are made from a medium carbon alloy steel. Grade 8 bolts are significantly stronger than an A325. An ASTM specification with similar strength properties to grade 8 is ASTM A490.


Also, what grade is an a325 bolt?

ASTM A325 is the standard specification for heavy hex structural bolts in heat-treated steel with a minimum tensile strength of 120/105 ksi. A325 bolts from Glaser and Associates are available in two grades, type 1 and type 3, offering different mechanical and chemical properties for specific applications.

Beside above, how can you tell if a bolt is grade 8? Look for Bolt Markings If you do not have a magnet you can still identify Grade 8 bolts by brushing the head of the bolt using a wire brush and counting its radial lines. There are six radial lines on the heads of Grade 8 bolts. Length is measured from under the head.

Herein, are all Grade 8 bolts the same?

Different grades of bolts are composed of different metal alloys and therefore have different mechanical properties. Grade 8 bolts are made of quenched and tempered medium carbon alloy steel. They are about twice as strong as grade 2 bolts, which are made from untempered carbon steel.

What is a Grade 8 bolt made of?

From the internet: Grade 8 bolts are comprised of carbon alloy steel, thus giving them a high psi rating. Zinc or yellow zinc grade 8 bolts are available to resist corrosion. The factor that makes a grade 8 bolt different from a lower grade bolt is its preload strength.
