Zoro Select M8 Class 10 Hex Nuts

This pack contains one hundred M8-1.25 hex nuts manufactured to DIN 934 dimensions from Class 10 steel with a zinc yellow finish. Each nut measures 13 mm across the flats and 6.5 mm in height. The right-hand metric threads suit standard M8 bolts and studs in automotive, industrial and general assembly tasks. The bulk quantity supports maintenance shops and production lines that need consistent stock on hand.

Upgrading from lower-grade or plain fasteners

Class 10 steel provides higher proof load than Class 8 or ungraded nuts, so the jump is worthwhile when joint integrity is critical or when the original specification calls for property class 10. The zinc yellow coating adds corrosion resistance compared with bare steel, extending service life in environments with moisture or road salt. Switching to this pack also standardises inventory around a single DIN 934 reference, reducing the risk of mixing grades during repairs.

Check thread pitch and clearance before ordering

Verify that the mating bolts are M8 with a 1.25 mm pitch; a coarse M8-1.0 or fine M8-1.5 thread will not engage correctly. Confirm that a 13 mm spanner or socket fits the installation space, as the hex width is fixed by the DIN 934 standard. Ensure the application does not require a prevailing-torque lock nut, a flange nut or a different property class, because this item is a standard hex nut only. The California Proposition 65 notice indicates the presence of listed chemicals, so handle accordingly.
