ISO 10511 Self-Locking Low Nut with Nylon Locking Ring

The ISO 10511 self-locking low nut with a nylon locking ring is designed as a low hexagon with an internal metric thread. It is used in various industrial fields as well as in construction. It serves to reinforce bolted connection assemblies, preventing them from spontaneously loosening. It is used together with threaded fasteners: screws, bolts, and studs with matching thread parameters and material.

Technical specifications of the ISO 10511 nut

The self-locking nut is made of carbon steel with zinc coating, A2 and A4 grade stainless steel alloys, and brass. A non-metallic insert serves as the locking element, most often a nylon ring. Along the outer perimeter, the top of the fastener’s faces are chamfered at a certain angle. Geometric parameters of the fastener:

• thread diameter from M3 to M24;
• overall height of the product 4-24 mm;
• width across flats of the hexagon 5.5-36 mm;
• distance between opposite corners of the hexagon 6.01-39.55 mm.

ISO 10511 nuts are characterized by a property class from 5 to 10.

Features of using self-locking fasteners

All metals recommended as raw material for manufacturing nuts have high strength, low wear, low specific weight, and significant corrosion resistance. Hence the breadth of application fields, including heavy and light machine building, construction, and automotive manufacturing.

The presence of a locking element in the upper area of the ISO 10511 nut allows customers to save on purchasing additional locking hardware: spring washers and multi-lobe washers, crown nuts, and other parts. The operation of this fastener is based on the principle of friction braking. The nut threads onto the fastener easily, but as it approaches the nylon ring, the tightening torque increases due to the resulting thread friction.
