Retainers have a cylindrical shape and are used to hold screws within a panel, so they are not misplaced when the screws are loosened. They are affixed to a board or panel using pressure or are swaged in and include a central hole that may or may not be threaded. Most often, they are paired with captive screws and can also accommodate a spring if needed.

We produce a variety of retainers including clear hole retainers, clear hole retainers spring recessed, retainer springs, threaded retainers, spring recessed threaded retainers, and retainer washers.

CAD files for stock retainers are available for download in our online store.
