USPHS COMMISSIONED CORPS SCREW CAP BUTTONS FOR COMBINATION CAP

In accordance with the United States Public Health Service Commissioned Corps’ Mil-Spec standards instituted in 2012 with an effective date of 1 January 2015, our screw cap retaining buttons are 9/16-inch in diameter and manufactured with certified Mil-Spec materials.

Embossed on the buttons is the Corps device of an upright caduceus mounted at a 90-degree angle on a fouled anchor, a design that replaced the old spread eagle clutching an anchor and surrounded by 13 stars that the service had borrowed from the United States Navy.
