M8‑1.25 x 40 mm DIN 6921 Hex Flange Bolt – Class 8.8, Plain Finish, Partial Thread

The M8‑1.25 x 40 mm DIN 6921 hex flange bolt is manufactured from metric Class 8.8 steel for strong, reliable fastening performance. Designed with a partial thread (PT) and coarse pitch, it provides improved shear strength and consistent load transfer in structural applications. The non‑serrated flange allows smooth, even load distribution while helping protect mating surfaces, eliminating the need for a separate washer. Finished in a plain (uncoated) condition, this bolt is ideal for machinery, equipment assembly, and industrial applications where secondary finishing or controlled environments are required.
