What is a F1554 anchor bolt?

F1554 is an ASTM specification for cast in place anchor bolts. It was established to clarify material properties for anchor rods used in concrete. Prior to it’s creation, concrete anchor bolts were most commonly specified using the generic round bar specification A36 or the headed hex bolt specification A307.

What does ASTM F1554 mean?

steel anchor bolts
ASTM F1554 is the newest construction fastener specification developed by the American Society for Testing and Materials and covers steel anchor bolts intended for anchoring structural supports to concrete foundations.

What is the grade of anchor bolt?

The most common grades used for anchor bolts are the high strength alloy steel grade L7 and the stainless steel grades B8 and B8M. Grade L7 anchor bolts require a Charpy test at -150 degrees Fahrenheit. This ASTM specification covers hot-dip galvanizing of bolts, nuts, washers, and other threaded parts.

What is F1554 55?

F1554 Grade 55 steel bar is a designed strength, low to medium carbon content grade. It has a 55 ksi yield strength which is required by the F1554 specification for anchor bolt and fastener applications.

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.

What is ASTM A563 Grade A?

ASTM A563 is a standard material specification for carbon and alloy steel nuts general structural and mechanical uses on bolts, studs, and other externally threaded fasteners. Find chemical and mechanical requirements for eight grades of carbon and alloy steel nuts covered by ASTM A563 specification.

What is Grade 55 all thread?

The reference to “Grade 55” is for getting a stainless steel all thread rod with a minimum yield strength of 55,000 psi. There are currently no stainless steel specifications commonly stocked that will guarantee a 55,000 psi yield strength.

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.

What kind of anchor Rod does ASTM f1554 use?

The specification for ASTM F1554 covers straight and bent, headed and headless, carbon, carbon boron, alloy, or high-strength low alloy steel anchor bolts (also known as anchor rods ). The anchor bolts are furnished in three strength grades, and in the sizes specified below

What kind of nut do you need for f1554 anchor bolts?

The required nut specification for all F1554 anchor bolts is ASTM A563, which is the general nut specification for structural and mechanical applications. Depending on the diameter and finish of the anchor bolt, ASTM requires an A563 hex or heavy hex pattern nut.

Which is the most common ASTM anchor bolt?

The most common one in use today is F1554 which is the ASTM anchor bolt specification. Nominal Size (In.) ASTM F1554 was developed to specifically cover anchor bolts and is the most widely used specification for this application. This specification includes 3 grades of anchor bolts including grade 36, 55, and 105.

What kind of steel is used in ASTM f1554?

While F1554 does not require Grade 55 to be weldable, all steel used to make F1554 Grade 55 anchor bolts at A&M Nut & Bolt meets supplementary requirement S1 for weldability. Grade 105 anchor bolts are the highest strength bolts within ASTM F1554. They are manufactured from a heat treated alloy steel, developing a minimum yield strength of 105 ksi.
