What is ASTM A307 Grade A?
What is ASTM A307 Grade A?
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.
What does ASTM A307 mean?
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 is an A307 anchor bolt?
A307 Grades Heavy hex bolts and studs intended for flanged joints in piping systems with cast iron flanges. The end of a grade C anchor bolt intended to project from the concrete will be painted green for identification purposes. Permanent marking is a supplemental requirement.
What is U-bolt used for?
A U-bolt is a bolt in the shape of the letter U with screw threads on both ends. U-bolts have primarily been used to support pipework, pipes through which fluids and gasses pass. As such, U-bolts were measured using pipe-work engineering speak.
What grade is A307 bolts?
Grade 2
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 difference between A307 and A325?
ASTM A325 bolts are assigned to “Group A” while ASTM A490 bolts are assigned to “Group B”. 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.
What is the U-bolt formula?
u-bolt diagram Regardless of the bend type, all U-bolts are measured in the same manner as shown here. The U-bolt size is given as Diameter(A) x Distance(B) x Leg Length(C).
Is A307 a Grade 5?
A307 is basically an ungraded bolt and A325 is grade 5 or so.
What grade is a A325 bolt?
SAE grade 5
As a comparison, the ASTM A325 bolt is roughly equivalent to the SAE grade 5. A grade 8 bolt would be one that meets ASTM A490 standards. The A325 bolt strength, or SAE grade 5 bolt strength, is usually used for structural bolting projects.
What are the grades of ASTM A307 bolts?
The ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4″ through 4″ diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar. There are three grades A, B, and C* which denote tensile strength, configuration, and application.
