Hex Bolt M30 Class 8.8 Pitch 3.50 is a hex head bolt for steel structures, heavy machinery, equipment bases and bolted joints requiring large-diameter coarse metric thread. 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 differs by M30/M33 with 3.50 pitch, not 3.00 pitch or an ASTM structural inch bolt; therefore it should not be replaced with a similar sister reference only because it has a hex head. The material reported for the lot is carbon steel. For classes 8.8 and 10.9, selection is based on ISO 898-1 as a reference for mechanical properties; for DIN 933, DIN 960 or DIN 961, full, partial or fine thread geometry is validated according to the drawing. For ASTM A325, A490 or A394 bolts, the project standard defines bolt, nut, washer and installation. We do not publish single load or torque values because they depend on lubrication, nut, washer, thread condition, grip length and engineering criteria.
