Lock Nuts - Metric Fine Pitch

M8 x 1.00P - Lock Nut Hexagon DIN 439B - A2 Stainless Steel - Pack of 5

Sometimes written as lock nuts, they also go by various other names, including half nuts, jam nuts and thin nuts.

Locknuts are used to lock a full nut in position to prevent it from working loose as a result of vibration or other factors.

Locknuts are often mixed up with Nyloc nuts, which are different. Nyloc nuts are self-locking nuts that feature a nylon collar in the top portion of the nut that locks the nut in place.

Metric fine thread is a common thread, often found on machine screws. More threads per axial distance (length along the fastener) than metric coarse. A fine thread is known to be stronger than a coarse thread.
