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 are 307A bolts used for?
A307 Grades Headed bolts, threaded rods and bent bolts intended for general applications. 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 does 307A mean on the head of a bolt?
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. It is generally used in low-pressure, standard or normal temperature applications and is made of low carbon steel.
Are there different grades of carriage bolts?
Grades 2 and 5, steel, and stainless steel, are the most prevalent types of carriage bolts. Common finishes for Grade 2 are zinc plating and hot dip galvanizing, and zinc plating for Grade 5.
Is A307 a structural bolt?
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 are Hex Bolts made of?
Their six-sided hex head allows for a more substantial bearing and wrenching surface than what socket products or machine screws can provide, thereby making them the clear choice in many complex and heavy duty applications. A307 Grade A Hex Bolts are manufactured from low or medium carbon steel.
What are galvanized hex bolts used for?
A307 Galvanized Hex Bolts. A Hex Bolt (named for its six-sided head), is the industry standard for fasteners with forged heads. This is commonly used for a variety of applications such as fastening of steel and wood, and as part of several construction projects including houses, buildings, bridges, highway structures, and the like.
What is a hex screw used for?
They are used to fasten 2 or more parts together in an assembly that may require future repair or maintenance disassembly. Their six-sided hex head allows for a more substantial bearing and wrenching surface than what socket products or machine screws can provide, thereby making them the clear choice in many complex and heavy duty applications.
