Knurled locking nut Stalgast C012772

A knurled locking nut grips a threaded shaft by converting finger pressure into radial force. The knurled outer surface gives purchase so the operator can tighten it by hand, while the internal thread bites into the shaft and resists loosening from vibration or thermal cycling. This design removes the need for spanners or wrenches in confined spaces typical of professional kitchens, where equipment is frequently disassembled for cleaning or reconfiguration.

To use the nut, the operator aligns it with the exposed thread of the shaft or bolt, then turns it clockwise until it contacts the mating surface. Further rotation increases the clamping force; the knurled rim allows sufficient torque to be applied by hand. Once seated, the nut remains secure without additional locking compounds, though it can be removed by reversing the rotation when the equipment is taken apart for service.

The nut is machined from a single piece of metal, giving consistent thread engagement and resistance to stripping. Its compact form fits into tight clearances where conventional fasteners would interfere with adjacent components or moving parts.

This knurled locking nut fits threaded shafts of the dimensions specified in its designation, making it compatible with Stalgast and other professional catering equipment that uses the same thread standard. It is listed in the catalogue under Fasteners and Spares for Catering Equipment.
