Esparragos ASTM a 325 B 7 Tuercas 2h, a-325 B7 Structural Hex Head Bolt
Basic Info
Model No.: A325 Hex Bolt
Product Description
Model NO.: A325 Hex Bolt Type: Round Head Head Style: Round Grade: A325 Hex Bolt Finish: Fluorocarbon Coated Trademark: C&N Origin: China Material: High Strength Steel Connection: Common Bolt Standard: DIN, ANSI, JIS, GOST Application: Machinery A325 Hex Bolt: A325 Hex Bolt Specification: The ASTM A325 The ASTM A325 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. Refer to the Structural Bolts page of our site for thread lengths and other related dimensions.
This specification is applicable to heavy hex structural bolts only. For bolts of other configurations and thread lengths with similar mechanical properties, see Specification A449.
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 1-1/2″ but with similar mechanical properties.
