Structural bolt ASTM A490 black 5/8is a hex head bolt for structural connections of alta strength in steel cuando the design exige A490 and finish black. At TECTUL it is quoted per unit and by actual available size, cross-checking diameter, length, pitch, material and standard before confirming price. This reference is differentiated by A490 black 5/8, not A325 galvanized; A490 must not be changed to galvanized without validating the current standard; therefore, it should not be replaced with a similar related item only because it has a hex head. The material reported for the lot is carbon steel with finish black. For class 8.8 and 10.9, selection is based on ISO 898-1 as the reference for mechanical properties; for DIN 933, DIN 960 or DIN 961, full, partial or fine thread geometry is validated against the drawing. For ASTM A325, A490 or A394 bolts, the project standard defines the bolt, nut, washer and assembly. We do not publish single load or torque values because they depend on lubrication, nut, washer, thread condition, grip length and engineering criteria.
