The Ultimate Guide To A490/F2280 Tension Control Bolts - Fasteners and Industrial

Note: In 2016, ASTM A490 was formally withdrawn and replaced by ASTM F3125, in which A490 now becomes a grade under the F3125 specification. The F3125 requirements is a debt consolidation and replacement of 6 ASTM requirements, consisting of; A325, A325M, A490, A490M, F1852, and F2280. We are choosing to keep this technical info about the now outdated A490 requirements on our website for reference and educational purposes just.

These bolts are intended for use in structural connections and for that reason have much shorter thread lengths than basic hex bolts. Refer to the Structural Bolts page of our site for thread lengths and other related dimensions. A490 bolts are comparable in application and measurements to A325 heavy hex structural bolts however are made from alloy steel rather than medium carbon steel, resulting in a greater strength fastener.

ASTM F3125 Grade F2280 (A490-TC)

For bolts with various thread lengths than defined for structural bolts however with comparable mechanical properties, see Specification A354 grade BD. ASTM A490 bolts will not be covered by hot-dip galvanizing, mechanical deposition, or electroplating with zinc due to the potential threat of hydrogen embrittlement. ASTM has authorized coating A490 bolts with Zinc/Aluminum Deterioration Protective Coatings per ASTM F1136 Grade 3, commercially called Geomet.
