A490 bolts are similar in application and dimensions to A325 heavy hex structural bolts but are made from alloy steel rather than medium carbon steel, resulting in a higher strength fastener. The A490 specification is applicable to heavy hex structural bolts only.

ASTM A490 - Standard Specification for Structural Heavy Hex Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength with Type 1 & Type 3 Weathering Steel Bolting Class. This specification covers two types of bolting grades quenched and tempered, manufactured from high strength alloy steel.

2023年3月8日 · The short answer is that F3125 Grade A490 heavy hex structural bolts have higher strength requirements than A325 heavy hex structural bolts. A325 bolts have a minimum tensile strength of 120ksi while A490 bolts have a tensile strength range of 150-173ksi.

AFT Fasteners provides a helpful resource on A325 & A490 bolts including: dimensions, material, hardness, proof load, yield strength and tensile strength.

ASTM A490 and ASTM A490M are ASTM International standards for heavy hex structural bolts made from alloy steel. The imperial standard is officially titled Standard Specification for Structural Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength , while the metric standard (M) is titled Standard Specification for High-Strength ...

ASTM A490 Type 1 is a high tensile bolting grade manufactured from high tensile alloy steel intended for use in structural connections. Type 1 Bolts are produced from 1/2" to 1-1/2" in imperial size as per ASTM A490 & from M12 to M36 in metric size as per ASTM A490M.

2014年11月28日 · Scope 1.1 This specification covers two types of quenched and tempered, alloy steel, heavy hex structural bolts having a tensile strength of 150 to 173 ksi. 1.2 These bolts are intended for use in structural connections.

ASTM A490 Type 3 is a high tensile bolting grade manufactured from weathering steel intended for use in structural connections. These type 3 bolts have higher strength than type 1 bolts. Type 3 Bolts are produced from 1/2" to 1-1/2" in imperial size as per ASTM A490 & from M12 to M36 in metric size as per ASTM A490M.

ASTM A490 bolts are heavy hex bolts made of alloy steel with a flat bearing surface, washer faced, and chamfered point. They are used in structural steel joints in heavy construction applications that require greater yield and tensile strengths than those of …
