What grade is an A307 bolt?
ASTM A307 Sizes & Specifications You will often hear about A307 and Grade 2 bolts as being equivalent. While they are small differences they each are referred to as “low carbon” fasteners. A307 is an ASTM (industrial) spec, while Grade 2 is an SAE J429 Grade 2 (automotive) spec.
What is the tensile strength of A307 threaded rod?
60,000 psi
Governing StandardsGrade A307A Covers the mechanical and material requirements for inch series fasteners in diameters from 1/4″ through 4″, made of carbon steel having a minimum tensile strength of 60,000 psi.
Are A307 bolts stainless steel?
ASTM A307 / A563 Hex Bolts, Stainless Steel hex bolts.
What is A307 all thread?
A307 All Thread Rod, Plated A307 is an economical low carbon material often manufactured using A36 round bar. Dimensional specifications are governed by ASME B18. 31.3. A307 all thread rod is available in zinc plated finish.
Is A307 a Grade 5?
ASTM A307 Tap Bolt: To be used in drilled and tapped holes which are threaded full length. Used instead of a stud and a nut. Grade-5 Tap Bolt: Used to mount motors to machinery; also popular in automotive and truck repair.
Is Grade 5 the same as A307?
Basically, they are the same. There are hardness, size, thread, as well as ASTM discrepancies between them. Overall mechanical properties are pretty much the same though.

What does 307A mean on a bolt?
What does 307 on a bolt mean? A 307 A bolt can be identified by the self –identifying stamp. 307A bolts are a Grade 1 equivalent that is used in low-strength application. It has lower hardness and tensile requirement than grade 2 bolts. Are A307 bolts high strength? ASTM A307 bolts are not assigned to a group since they are not considered to be high strength bolts.
What grade is A307 bolt?
The A307 Thru Bolt and others in the grade A come with 60ksi minimum tensile strength while grade B can range from 60 to 100ksi and grade C from 58 to 80ksi minimum tensile strength values. The astm a307 stud bolt is used with applications where the stud is needed. The material has carbon, manganese, phosphorus and sulfur in the composition.
Are A307 bolts weldable?
Are a307 bolts weldable? Often times, ASTM A307 bolts (and all thread rod) are manufactured from A36 steel, but not always. A36 material should always be weldable and if A307 rods are manufactured from A36 steel, they will be weldable as well. However, A307 bolt can be made from other steels which, in rare instances, may not be weldable.
What is A307 bolt grade?
Grade 2 bolts ( A307) are a standard hardware grade steel. This is the least expensive and most common. They have a tensile strength of 60,000 PSI. Grade 5 bolts are a heat treated carbon bolt. Hardened to increase its strength, it’s most commonly found in automotive applications.
