What nut goes with A325 bolt?

The recommended grade of nut for an ASTM A325 structural bolt is ASTM A563 Grade D, DH, or C. ASTM A194 2H is also an acceptable substitute. These ASTM grades are all high strength and go through a heat treating process required to develop their mechanical characteristics.

What is A325 material?

ASTM A325 specification covers two types of quenched and tempered steel heavy hex bolts in metric and imperial sizes for structural purpose. The specification includes type 1 & type 3 fastener material intended for structural bolting purpose.

What does grade A325 mean?

ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from 1⁄2 to 11⁄2 inches (13 to 38 mm) in diameter.

What is A325 Type 1 bolt?

ASTM A325 Type 1 is a standard material specification for high strength carbon steel fasteners, for use in high tensile structural bolting and other general purpose applications.

What grade is an A325 bolt?

The A325 bolt strength, or SAE grade 5 bolt strength, is usually used for structural bolting projects.

What is the difference between A325 and Grade 8 bolts?

A325 bolts are typically manufactured from a medium carbon steel (although they can be made from an alloy) while SAE grade 8 bolts are made from a medium carbon alloy steel. Grade 8 bolts are significantly stronger than an A325. An ASTM specification with similar strength properties to grade 8 is ASTM A490.

Is A325 stainless steel?

Whereas stainless steels consist of chrome and nickel, A325 bolts have a chemical composition of medium carbon or medium carbon alloy steel that is quenched and tempered.

Is A325 high strength?

Prior to its withdrawal in 2016, the ASTM A325 specification covered high strength heavy hex structural bolts from 1/2″ diameter through 1-1/2″ diameter. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts.

Is A325 high strength bolt?

A325 bolts have a minimum tensile strength of 120,000 PSI for one inch or less diameters and 105,000 PSI for over one inch. This makes them weaker than A490, certain jobs do not require a structural bolt as strong as Grade A490.

Which is stronger A325 or Grade 8?

Strength Differences A325 bolts are typically manufactured from a medium carbon steel (although they can be made from an alloy) while SAE grade 8 bolts are made from a medium carbon alloy steel. Grade 8 bolts are significantly stronger than an A325.

Is A325 stronger than Grade 8?

Is A325 stronger than 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.

Is A325 stronger than A307?

The Strength of A325 Bolts Compared to A307 bolts, A325 are generally higher strength. As such, they are used for different applications. The ultimate tensile strength of A325 bolts is 120 ksi, double that of an A307 A grade bolt.

Is A325 carbon steel?

A325 Types Medium carbon, carbon boron, or medium carbon alloy steel.

How much weight can a A325 bolt hold?

ASTM A325 bolts are available in diameters from ½ to 1-1/2 inch diameters (for diameters greater than 1-1/2, ASTM A449 specifications should be considered) with a minimum tensile strength of 120,000 PSI for diameters one inch and less and 105,000 PSI for sizes over one inch to 1-1/2.

Are titanium bolts stronger than steel?

Applications for Titanium Fasteners The strength and low weight of Titanium make it exceptionally unique, and some grades of Titanium can be anywhere from two to four times stronger than Stainless Steel.

What is the strongest metal bolt?

BUMAX® Ultra has proven itself as the world’s strongest bolt – in various highly-demanding critical fastener applications around the world where standard fasteners are simply inadequate.

Are A325 bolts high strength?

ASTM A325 covers high strength structural bolts used in structural steel connections. A325s have a heavy hex head, a full body diameter, and are normally short in overall length since they are connecting steel to steel.

Do titanium bolts break?

Some mechanics use waterproof grease, anti-seize compound, Loctite or a mixture of the two (careful, some may not mix). If a titanium bolt does break, the harder material is much more difficult to drill out.

What is the difference between an A325 and A490 bolt?

Answer (1 of 2): Grade A325 can be made of Type 1 medium carbon steel or Type 3 weathering steel. An important distinction between A325 and A490 is that it A325 Type 1 bolts can be galvanized. A325 bolts have a minimum tensile strength of 120,000 PSI for one inch or fewer diameters and 105,000 PS…

How to determine A325 structural bolt length?

Itis the sum of the thicknesses of all the partsbeing joined exclusive of washers • Thread length is the threaded portion of the bolt • Boltlength is the distance frombehind the bolt head to the end of the bolt (AISC& NISD 2000) Parts of the Bolt Assembly

What grade is A325?

The Grade 5 specification falls under the Society of Automotive Engineers (SAE) classification system, while A325 is an ASTM specification. ASTM A325 bolts are more commonly specified by engineers for use in structural steel connections on heavy construction projects, while SAE Grade 5 bolts are more common in OEM-type applications.

What is the shear strength of a Grade 5 bolt?

Grade 5 carriage bolts are made from carbon steel and have a tensile strength of 120,000psi, and have a proof load strength of 85,000psi. They have a tensile strength of 150,000 psi and a shear strength of 90,000 psi.
