M8 x 1.25 mm Left-Hand Flange Nuts

These five 304 stainless-steel nuts feature a serrated flange and left-hand M8 x 1.25 mm threads. The hexagonal head and integrated flange distribute clamping load while protecting the mating surface. They suit maintenance, repair and assembly tasks where vibration could loosen standard right-hand fasteners.

Engineers securing rotating shafts

Technicians needing right-hand threads or a different thread pitch should select another fastener. The pack contains only five pieces, so large-volume production lines will require multiple packs or bulk alternatives. Builders who need nylon-insert locking or a non-serrated bearing face must choose a different nut style.

Serrated flange resists loosening under sustained

The 304 stainless material maintains clamp force and corrosion resistance during prolonged exposure to moisture, chemicals or temperature cycling. Serrations bite into the joint face, preventing back-off without additional lock washers. The flange spreads load to reduce embedding in softer materials over long service intervals.

Questions about this item

What size bolt or stud do these M8 x 1.25 mm left-hand nuts fit?

They fit any M8 bolt or stud with a 1.25 mm pitch and a left-hand thread, so the mating part must share that exact diameter and pitch.

Can I mix these serrated flange nuts with standard right-hand M8 hardware on the same assembly?

No, because these nuts tighten counter-clockwise while standard M8 hardware tightens clockwise; mixing thread directions on one assembly will prevent proper clamping.

How can I confirm the serrated flange is gripping correctly after installation?

The nut should resist loosening when the joint is vibrated, and the serrations should leave visible witness marks on the mating surface when the nut is removed.
