Using cheap hardware is a false economy.

Hardware and locks must conform to REACH standards. Any substances that are on the RSL (restricted substance list) cannot be used.

Hardware and fittings must be fit for usage purpose. They must be free from contamination, oxidation and all other types of degraded corrosion – Tarnishing, pitting and rusting. All metal must be free from nickel and ferrous release. Hardware must be tested to the relevant EU or US standards. .

Storage & humidity can affect plating. All plated products must be correctly stored.

All hardware should be doing twice inspection before delivery. Rejected hardware must be segregated and stored in a separate, clearly marked area.

PLATING
Electroplating is the only method of plating permitted and must be plated to a minimum thickness of 2.0 u
Lacquer hardeners are acceptable to be used to protect the plating from corrosion. However this must be through electrification and not through spray application.
Ensure that correct cross linking is provided whilst lacquering any hardware. The plating finish of the hardware must match with all elements of hardware and locks within the bag, unless specified by Design/Buying.

LOCKS
All locks must be inspected prior to use in production. It is a requirement that 100% inspection is carried out and locks that are not fit for purpose are not used in production.
Screw and Back Plate fixings
Screw heads must be sufficient in length to pass through all layers of material with enough of a tolerance to screw into the front plate. Screws to be locktite glued as well.
Ensure that both parts of the lock open and close smoothly. Each part must be deep enough to accommodate the other part.

Screws
All screws used in attaching fittings must be fit for purpose, fit securely and be matched in colour and finish.
The screws on the back plate must be substantial enough to support the weight of the lock.
Screw heads must be flush to the fitting and not cause damage the main body. When using any plate ensure that the screw length is correct.
Screws must be covered by clear adhesive once in place to hold them securely (this is called ‘Lock Lacquered’)
Screw heads must be free from rough/sharp edges.
