The T in the designation ASTM A325T invokes supplement S1 in ASTM A325, which allows for full-length threading (ASTM A325T). This provision may be specified for ASTM A325 bolts of length less than or equal to four times the bolt diameter only; there is no similar provision in ASTM A490.
A325 A490 Heavy Hex Bolts Structural Hex Bolts Heavy Hex Bolts. Haydon Bolts stocks heavy hex bolts in the sizes listed, at the bottom of this page, in our warehouse. Because of our manufacturing expertise Haydon Bolts is able to custom manufacture structural bolts to from 1/2 to 4 diameter, in a variety of lengths and grades, as a result we are able to shorten lead times for our customers.
* Important note:Some bolts may vary from the standard thread length. Trying to make sense of all the different screw and bolt thread lengths can be a real challengeeven for the
Bolt Torque Calculator - Determining Proper Torque to Bolt As an example, we can utilize the equation to find the correct torque value for a zinc-plated, heavy structural bolt, in this instance belonging to ASTM A325 with a ¾ inch diameter and 10 TPI. As = /4 x (3/4in. - (.938194/10))². As = .3383 in². Using this value, the clamp force can now be identified. P = 85,000 x .3382. P= 28,747 lb.

Structural Bolting Structural Bolting The Research Council on Structural Connections (RCSC) prepares specifications and documents related to structuralconnections RCSCs Specification for Structural Joints Using ASTM A325 or A490 Bolts (2000) is a widely used specification which discusses joints, fasteners, limit states, installation, and inspections Structural Bolting 3
Structural Bolts - Portland BoltIn these applications, substitutions of A449 for A325 and A354 grade BD for A490 should be considered. Manufacturing. Portland Bolt manufactures A325 and A490 heavy hex structural bolts from 1/2 diameter through 1-1/2 diameter, typically in lengths longer than those which are normally available in the marketplace. Cutting; Heading; Threading
Second, the shank length (non-threaded portion of the body) on the A325 and A490 bolts is designed to be greater (shorter thread lengths) than your standard hex bolt or hex cap screw. Remember, the weakest section of standard carbon steel fasteners is through the threaded region. Minute design
Structural bolts A325, Hot dipped galvanized steel, 5/8 Structural bolts A325, Hot dipped galvanized steel, 5/8"-11. Hex bolt length is measured from under the head to the end of the bolt. Important Note:Due to the plating thickness, only hot dipped galvanized nuts should be used on hot dipped galvanized hex bolts.
Tension Control (TC) Bolts BACO EnterprisesThese TC bolts are made from high-strength steel and are available in many different diameters and lengths. The diameters we carry range from 5/8" to 1 1/8" in every length manufactured up to 8 1/2" long. A325 Tension Control (TC) Bolts Quality And Performance Considerations
Tension Control Bolts, TC Bolts or Twist Off Bolts are now the most popular choice in high-strength structural bolting and formally recognized by the AISC (American Institute of Steel Construction) and the RCSC (Research Council on Structural Connections) as an approved installation method. A Tension Control Bolts consists of 1 bolt, 1 nut and 1 washer, pre-assembled and there for they are ASTM A325 Bolts Dimensions Chart, Strength, Grade A325 ASTM A325 bolt strength are summarized in the table bellow inluding tensile strength, yield strength and hardness, etc. Notes:The stress area is calculated as follows:A s = 0.7854 [D- (0.9743/n)] A s = stress area, in 2, D = nominal bolt size, and. n = threads per inch.
