Astm A325 Bolts Mechanical Properties

This specification is a consolidation of and replacement for six astm standards ranging from 1 2 through 1 1 2 diameter.

Astm a325 bolts mechanical properties.

In addition you will find the estimated mechanical property requirements for each diameter of bolt required. No other units of measurement are included in this standard. 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. 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 1 1 2 in diameter. But with similar mechanical properties. A325 structural bolts astm a325 covers high strength structural bolts used in structural steel connections. Dimensions meet asme b18 2.

It defines mechanical properties for bolts that range from 1 2 to 1 1 2 inches 13 to 38 mm in diameter. Length is measured from under the head. 1 4 the values stated in inch pound units are to be regarded as standard. The most common heavy hex head screw these steel screws meet astm a325 regulations for structural joints such as mating i beams and scaffolding.

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. 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. Material meets astm f3125 specifications for quality. Properties below are the chemical and mechanical requirements per the astm a325 specification.

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. A325 a325m a490 a490m. 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. Partially threaded screws come with precise threaded and unthreaded portions allowing you to place only the.

It defines mechanical properties for bolts that range from 1 2 to 1 1 2 inches 13 to 38 mm in diameter. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts.
