Astm A325 Bolts Mechanical Properties

Prior to its withdrawl in 2016 the astm a325 specification covered high strength heavy hex structural bolts from 1 2 diameter through 1 1 2 diameter.

Astm a325 bolts mechanical properties.

1 4 the values stated in inch pound units are to be regarded as standard. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts. A325 a325m a490 a490m. In addition you will find the estimated mechanical property requirements for each diameter of bolt required.

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. Partially threaded screws come with precise threaded and unthreaded portions allowing you to place only the. Material meets astm f3125 specifications for quality. It defines mechanical properties for bolts that range from 1 2 to 1 1 2 inches 13 to 38 mm in diameter.

The most common heavy hex head screw these steel screws meet astm a325 regulations for structural joints such as mating i beams and scaffolding. This specification is a consolidation of and replacement for six astm standards ranging from 1 2 through 1 1 2 diameter. Properties below are the chemical and mechanical requirements per the astm a325 specification. A325 structural bolts astm a325 covers high strength structural bolts used in structural steel connections.

Astm a325 type 3 specification for heat treated weathering steel structural bolts steel heat treated with 120 ksi minimum tensile strength astm a325 type 3 is a standard material specification for high strength weathering steel fasteners for use in high tensile structural bolting and other general purpose applications. This specification covers the chemical physical and mechanical requirements for structural bolts manufactured from steel and alloy steel in two strength grades two styles and two types. One thing to note is that with the implementation of astm f3125 grade a325 the mechanical properties differ slightly as indicated below. A325s have a heavy hex head a full body diameter and are normally short in overall length since they are connecting steel to steel.

It defines mechanical properties for bolts that range from 1 2 to 1 1 2 in diameter. Astm a325 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. Length is measured from under the head. Dimensions meet asme b18 2.

But with similar mechanical properties. Note 1 bolts for general applications including anchor bolts are covered by specification a 449 also refer to specification a 449 for quenched and tempered steel bolts and studs with diameters greater than 1 in.
