Are A307 bolts high strength?
ASTM A307 bolts are not assigned to a group since they are not considered to be high strength bolts. The ultimate tensile strengths for A325 and A490 bolts are 120 ksi and 150 ksi respectively.
How strong is a grade A307 bolt?
60,000 psi
Governing StandardsA307 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.

What grade is A307 bolts?
ASTM A307 Grade A is a standard material specification for medium strength carbon steel fasteners specially bolts, studs and threaded rods for general purpose applications. Grade A is a heat treated carbon steel bolting material with minimum tensile requirement of 60 ksi and hardness range from 121 to 241 BHN.
Is A307 a Grade 5?
A307 is basically an ungraded bolt and A325 is grade 5 or so.
What does 307 on a bolt mean?
ASTM A307 Grade A Carbon Steel Bolting with minimum tensile of 60 ksi. ASTM A307 Grade A is grade specification in carbon steel bolting for use in general purpose application. This grade covers hex headed bolts, stud bolts, threaded rods or any other bolting having a minimum tensile strength of 60 ksi.
What grade is a A307 bolt?
Is A307 and F1554 the same?
Although A307 grade C and F1554 grade 36 are virtually identical, there are some subtle yet very important differ- ences. The ASTM F1554 specification was introduced in 1994 and covers anchor rods† designed to anchor structural sup- ports to concrete foundations.
Is A307 a structural bolt?
A307 Grades Nonheaded anchor bolts, either bent or straight, intended for structural anchorage purposes.
Is A307 the same as Grade 36?
Can you weld A307 bolts?
A307 bolts, rods, and studs are not always weldable. For this grade to be weldable it must meet the supplementary requirement S1 of the ASTM A307 specification. This supplement provides assurances of weldability by additional chemical composition restrictions and by a carbon equivalent formula.
