What Are ASTM A307 Fasteners?
ASTM A307 Fasteners refer to a standard specification (ASTM A307 / A307M) that outlines the chemical and mechanical requirements for externally threaded carbon steel bolts, studs, and threaded rods with a minimum tensile strength of 60,000 PSI. These fasteners are a staple in many industries due to their good strength, versatility, and economic value.
The ASTM A307 specification has outlined three grades of A307 fasteners which denote tensile properties and usage:
- ASTM A307 Grade A Bolts: These bolts have been developed for mainly general purpose fasteners. Generally, these consist of headed bolts, studs and threaded rods.
- ASTM A307 Grade B bolts and nuts: This grade is intended specifically for flanged joints in piping systems. In particular, flanged joints with cast iron flanges. Grade B fastener includes controlled range of tensile strength (60 ksi to 100 ksi).
- Grade C (Obsolete): This includes previously non-headed anchor bolts and studs. This has been superseded with specifications such as ASTM F1554 Grade 36. Jade Special Metals can supply fasteners meeting these updated anchoring standards.
It’s important to note that the ASTM A307 specification does not cover certain types of fasteners like machine screws, thread-forming or thread-cutting screws, and mechanical expansion anchors. Products manufactured under ASTM A307 are carefully tested to ensure they adhere to specified values for chemical composition, mechanical properties (including tensile strength, elongation, and hardness where applicable), and dimensional accuracy.

Applications of ASTM A307 Bolts
The reliability and cost-effectiveness of ASTM A307 Bolts make them ideal for a wide variety of general purpose and industrial fastening applications:
General Construction: Fastening wood, steel, and other construction materials used in buildings, docks and highway structures.
Piping Systems: ASTM A307 Grade B bolts and nuts are especially made for flanged joints, especially with cast iron flanges, in waterworks, plumbing, and industrial piping systems.
Machinery & Equipment Assembly: For general fastening of components where high-strength alloy or stainless steel is not required.
Infrastructure Projects: Used in bridges, supporting structures, and other improvements for public use.
Wood Construction: Carriage bolts and lag bolts for timber connections.
Anchoring Applications: Foundation bolts and anchor rods for securing structures (though F1554 is often preferred for dedicated anchor bolts).

FAQ’s About ASTM A307 Fasteners
What is the ASTM A307 specification?
ASTM A307 is a standard for common, everyday carbon steel bolts, studs, and threaded rods. These fasteners are used for general-purpose applications where high strength is not required, such as in construction, anchoring, and machinery assembly. The specification is divided into different grades, with Grade A and Grade B being the most common.
What is Grade A307 tensile strength?
The main difference is their intended use and strength limits:
- Grade A: Intended for a wide range of general applications. It has a minimum tensile strength of 60,000 PSI.
- Grade B: Specifically designed for flanged joints in piping systems with cast iron flanges. It has a minimum tensile strength of 60,000 PSI but also a maximum limit of 100,000 PSI to ensure the bolts don’t damage the flanges.
What material is SA 307?
A307 fasteners are made from low-carbon steel. This makes them a cost-effective choice for standard applications that don’t face extreme temperatures or high-stress loads.
What is A307 material equivalent to?
The closest equivalent to an ASTM A307 bolt is an SAE J429 Grade 2 bolt. Both are low-carbon steel fasteners with similar strength requirements.
Are A307 bolts weldable?
Generally, no. While A307 bolts are often made from weldable steel (like A36), the A307 standard itself does not require the steel to be weldable. Because the material can vary, you should never assume an A307 bolt is weldable unless you have a specific material certification confirming it. For applications requiring welding, it is safer to use a material specifically designated for that purpose.
