Yes, we offer a variety plating/coating options including black oxide and infused chromium plating.  Chromium plating is an excellent choice for low friction, high wear applications especially where lubrication is limited.
Precision plating deposition faithfully duplicates thread contours eliminating the edge build or “dog-boning” associated with conventional chrome-plating processes.  In some instances, it may be necessary to adjust the thread profile to compensate for plating thickness in order to ensure proper screw and nut fit-up.
For operation in corrosive environments, stainless steel screws should be considered since they are generally more cost effective than plated screws.
All Rempco screws are shipped with an oil spray coating to inhibit oxidation.
