What is the yield strength of A307 bolts?
Strength Requirements by Grade
| Specification | Material and Treatment | Mechanical Properties |
|---|---|---|
| Yield Strength Min (ksi) | ||
| A307 Grade C | Low or Medium Carbon Steel | 36 |
| F1554 Grade 36 | Low or Medium Carbon Steel | 36 |

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.
How strong is Grade A307?
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.
Is A307 high strength?
As mentioned above, A307 A bolts cover the group of headed bolts, threaded rods, and bent bolts. A307 bolts are not considered high strength bolts. Wooden applications will typically use A307 bolts, for instance. Grade B A307 bolts can have a higher strength and are used for different applications.
What is the difference between A307 Grade A and B?
ASTM A307 is a specification that covers mild steel bolts. There are two grades within the ASTM specification. A307 grade A covers bolts for general applications, while A307 grade B covers heavy hex bolts and studs for cast iron flanges.
Is Grade 5 stronger than A307?
Basically, they are the same. There are hardness, size, thread, as well as ASTM discrepancies between them.
Is A307 a Grade 2?
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.
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 A307 the same as Grade 2?
Is Grade 8 stronger than A307?
Common ASTM grades include A307, which roughly corresponds to SAE Grade 2. An ASTM A325 bolt is roughly equivalent in strength to SAE Grade 5 and an A490 bolt is about equivalent in strength to SAE Grade 8.
Is A307 a Grade 8?
ASTM A307 Tap Bolt: A low carbon, hex head bolt with a machined point which is threaded to the head. Grade-5 Tap Bolt: A tap bolt made from medium carbon steel. Grade-8 Tap Bolt: A tap bolt made from medium carbon alloy steel and heat-treated. Stainless Tap Bolt: A tap bolt made from 18-8 stainless steel.
