ASTM A193

Alloy steel and stainless steel bolting materials for high temperature or high pressure service.

ASTM A307

Carbon steel bolts and studs, 60,000 psi tensile strength.

ASTM A320

Alloy steel and stainless steel bolting materials for low temperature service.

ASTM A325

Structural bolts, steel, heat treated, 120/105 ksi minimum tensile strength. Replaced by ASTM F3125.

ASTM A354

Quenched and tempered alloy bolts, studs, and other externally threaded fasteners.

ASTM A449

Quenched and tempered steel bolts and studs for general use.

ASTM A490

Structural bolts, alloy steel, heat treated, 150 ksi minimum tensile strength. Replaced by ASTM F3125.

ASTM F593

Stainless steel bolts, hex cap screws, and studs.

ASTM F1554

Anchor bolts designed to anchor structural supports to concrete foundations.

ASTM F3125

New, unified structural bolt specification replacing A325, A325M, A490, A490M, F1852, and F2280

AASHTO M164

The AASHTO M164 specification covers 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. This standard is identical to ASTM A325.

SAE J429

Mechanical and material requirements for externally threaded fasteners.

AASHTO M253

The AASHTO M253 specification covers quenched and tempered, alloy steel, heavy hex structural bolts from 1/2″ diameter through 1-1/2″ diameter with a minimum 150 ksi tensile. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts. This standard is identical to ASTM A490.

AASHTO M291

The AASHTO M291 specification covers the chemical and mechanical requirements for carbon and alloy steel nuts used on bolts, studs, and externally threaded fasteners from ¼” through 4”. This standard is identical to ASTM A563.

AASHTO M314

The acronym AASHTO stands for American Association of State Highway Transportation Officials. The AASHTO MM314 specification covers anchor bolts designed to anchor structural supports to concrete foundations. M314 anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. The three grades 36, 55, and 105 designate the minimum yield... Read more
