304 316 Stainless Steel Slotted Round Nut With Fine Extra Fine Thread GB810 GB812 Standards For Shaft Locking

This listing supplies two types of slotted round nuts manufactured to GB810 and GB812 standards in 304 and 316 stainless steel. Available in metric sizes from M10 to M200 with fine thread and extra-fine thread options, these nuts are commonly assembled with lock washers for mechanical anti-loosening on shaft components.

The GB812 standard-height round slotted nut provides stronger clamping force for general-purpose shaft locking applications. The GB810 low-profile thin-type round nut is specially designed for limited axial installation space where standard height nuts cannot be accommodated.

Evenly distributed outer slots allow lock washer tabs to clip securely into place, providing positive mechanical locking against rotation under continuous vibration and dynamic loads. Fine and extra-fine threads deliver precise adjustment and controlled tightening travel for optimal performance.

Threads are precision-rolled with full thread profile for smooth assembly without burrs or jamming. Stainless steel construction offers outstanding anti-rust and salt-spray performance, making these nuts well-suited for demanding industrial environments.

The comprehensive size range covers applications from small M10 up to large M200. Both samples and bulk orders are accepted. Matching stop lock washers can be supplied together for complete one-stop sourcing solutions for machinery manufacturing and maintenance projects.
