– Round nuts in steel, stainless steel or bronze.
We also supply flange nuts, square nuts, custom threads and left-hand threads.
FINE STEP
Fine pitch metric thread is mainly used in the automotive industry. The screw pitch is smaller, which means the screws are less likely to loosen due to vibrations. Castle nuts and fine pitch locknuts are also used in applications where fine adjustment is required.
We supply fine pitch screws in various materials, from size M2 to M110.
LEFT THREAD
Most threads are right-hand threads, meaning the screw is tightened clockwise. However, there are also left-hand threads for special applications, such as mounting the left pedal of bicycles or gas cylinders.
We supply standard screws with right and left threads. Any special item requiring a left-hand thread can be custom made.
