Unknown Facts About A325 Tension Control Bolt Assembly - Abrafast

Note: In 2016, ASTM A490 was officially withdrawn and replaced by ASTM F3125, in which A490 now becomes a grade under the F3125 requirements. The F3125 specification is a consolidation and replacement of six ASTM requirements, including; A325, A325M, A490, A490M, F1852, and F2280. We are choosing to keep this technical details about the now outdated A490 requirements on our website for reference and informational purposes just.

These bolts are meant for use in structural connections and for that reason have much shorter thread lengths than standard hex bolts. Describe the Structural Bolts page of our website for thread lengths and other associated measurements. A490 bolts are comparable in application and dimensions to A325 heavy hex structural bolts however are made from alloy steel rather than medium carbon steel, leading to a greater strength fastener.

For bolts with different thread lengths than defined for structural bolts but with comparable mechanical residential or commercial properties, see Requirements A354 grade BD. ASTM A490 bolts will not be covered by hot-dip galvanizing, mechanical deposition, or electroplating with zinc due to the possible threat of hydrogen embrittlement. ASTM has actually authorized covering A490 bolts with Zinc/Aluminum Rust Protective Coatings per ASTM F1136 Grade 3, commercially called Geomet.
