Is A307 the same as Grade 5?
Basically, they are the same.
What grade is a A307 bolt?
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 is stronger than a Grade 5 bolt?
Grade 8 / Grade G Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions.
Is A307 a structural bolt?
A307 Grades Nonheaded anchor bolts, either bent or straight, intended for structural anchorage purposes.
What is A307 Grade?
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.
How strong is a grade A307 bolt?
60 ksi
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 is a Grade 5 bolt?
Grade 5 Bolts and fasteners are made of medium strength carbon steel and are specified under the Society of Automotive Engineers (SAE). If your application calls for heavier materials, you may need Grade 8 Bolts because they are the hardest and are often used in heavy manufacturing applications.
What is a A307 bolt used for?
A307 Grades Heavy hex bolts and studs intended for flanged joints in piping systems with cast iron flanges. Nonheaded anchor bolts, either bent or straight, intended for structural anchorage purposes.
What bolt is the strongest?
Grade 9 structural bolts, also known as grade 9 hex cap screws, are one the strongest structural bolts that can be used today. While the typical grade 8 bolt has a tensile strength of 150,000 PSI, a grade 9 bolt has a tensile strength of 180,000PSI.
What grade bolt should I use?
The standard strength grade (or Property Class as it is known in the standards) for many industries is 8.8. On the head of the bolt, 8.8 should be marked together with a mark to indicate the manufacturer.
What is ASTM A307 steel?
The ASTM A307 is an ASTM International standard for carbon steel bolts and studs ranging from 1/4 inches through 4 inches in diameter which is set by the standards organization ASTM International. Given here is the bolt torque chart for the ASTM A307 bolts.
What is SAE grade 5 bolt?
Grade 5 bolts are a medium hard bolt and have 3 lines on the head. Grade 8 bolts are made out of alloy steel and heat treated to a real high tensile. Grade 8 bolts have 6 lines on the head. The specification number SAE J429 is the standard that covers these grades, and many other grades that are not as commercially available as these three are.
What is Grade 5 bolt strength?
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. Grade 5 bolts have 3 evenly spaced radial lines … resembling an airplane propeller.
