Use these values for early selection. Final dimensions, tolerances and loads are confirmed by engineering review and approved samples.
Professional door lock springs, durable, suitable for lock mechanisms and security devices
Handle return, latch extension and position retention.
Clutches, sensing and motor-assisted mechanisms.
Cabinet locks, door controls and retention.
Lock feel comes from spring force, friction, tolerance and lubrication. Increasing torque alone can add wear or excessive operating force.
Left / right projects benefit from clear part numbers, packaging and geometry that discourages reversal.
Design BasicsSeparating viewing direction, loading direction and free angle prevents reversed parts and angle errors during sampling.
Failure & LifeCyclic failure is rarely a material-only problem. Working stress, surface condition, heat treatment and installation all matter.
Materials & FinishesA finish should address corrosion, conductivity, appearance, friction or joining while accounting for dimensions and embrittlement risk.
Use the real lock or an equivalent fixture with representative angle, frequency, lubrication and temperature, monitoring torque loss and return.
Salt spray compares finish systems but does not replace wear, trapped moisture and cycling in the actual assembly.
