A394 & A325 - Constructed items general discussion - Eng

The A394-T0 is a regular strength bolt (IIRC it is comparable to A-307) while the A394-T1 is a high strength (and more expensive) bolt that is the same strength (shear anyway) as a A325 bolt. The physical difference is the bolt head dimensions. The A394-T1 (and T0) has the smaller head while A325 has the larger bolt head. ASTM A307 - Portland BoltThe ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4 through 4 diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar. There are three grades A, B, and C* which denote tensile strength, configuration, and application.

Design of Bolts in Shear-Bearing Connections per AISC

from shear planes, i.e. A325-X or A490-X In addition, when a bolt carrying load passes through fillers or shims in a shear plane, the provisions of LRFD section J3.6 apply. Values of design shear strength for A325, A490, and A307 are listed in LRFD Table 7-10 7.

Geometric Layout of Structural Bolts a) Size and Use of Hole (LRFD section J3.2) Grades - All Thread RodIt is intended for general engineering applications. Many engineers incorrectly specify A325 all thread rod, which is not a proper specification due to fact that A325 requires a forged head. ASTM A449 is virtually identical in chemistry and strength to the ASTM A325 specification in diameters 1/2 1; however, A449 is more flexible

Specifications - Headed Anchor Bolts

ASTM A307. A307 covers carbon steel bolts and studs. A307 bolts are available in Grade A (intended for general use) and Grade B (intended for use in flange applications). A307 Grade C was an unheaded anchor bolt specification that was replaced by ASTM F1554 Grade 36 in 2007. A307 is no longer an appropriate anchor bolt specification.

What Are the Different Grades of Bolts? Hunker

Its strength grades are indicated by the letter A plus three numerals stamped on the bolt head. Common ASTM grades include A307, which roughly corresponds to SAE Grade 2. An ASTM A325 bolt is roughly equivalent in strength to SAE Grade 5 and an A490 bolt is about equivalent in strength to SAE Grade 8.
