ABOUT HCB - ONE HEXAGONAL SELF-LOCKING SLOTTED LOW NUT ALL METAL

The principle

The principle of self-locking nut HCB is to compress the flank thread of the male element on a sector.
This principle is obtained by making a calibrated slot in the central part of the hexagon of the nut (Height = 0.8 Diameter), which is then crushed under a specific load to obtain a permanent elastoplastic deformation.
When assembled, the HCB nut returns to its original shape by generating pressure on the side of the flank of the male element on a sector creating a constant braking torque (called self-braking). This self-locking torque is independent of the tightening torque applied when tightening the HCB nut.

Applicable Industry

● Railway & Transports

Self-locking nuts are used on passenger’s trains,freight equipement, track works, electrification, metro, tram and buses.
Wheteher it’s for high speed train, metro or freight wagon, there is always a common purpose: that J. Lanfranco’s nuts are functional ans ensue the safety. When public safety is at staeke, there must be no risk taken with your fastening systems.

● Energy

Self-locking nuts have been chosen for their reliability in response to the most demanding requirements of players in the petrochemical industry. The use of J. Lanfranco nuts on compressors meets the unfailing expectations of the petrochemical industries. The company J. Lanfranco offers a complete range of self-locking nuts for all types of installations.

● Mining & Cement

Vibrating tables are subject to some of the most demanding service conditions: strong repeated shocks and vibration. This is often the bottleneck of mining since the premature loosening of screens causes unplanned shutdowns. The unanticipated sieve replacement results in: Reduced production throughput
、A decrease in profitability.Many customers have chosen ESL and ERM self-locking nuts for the operating performance, as well as for the ease and speed of maintenance.
