The SK2600-4S is a stainless steel quarter-turn fastener stud used in aircraft cowling and access panel systems. It belongs to Skybolt’s 2600 series (Camloc-compatible CLoc system) and is designed for quick installation and removal of panels using a slotted drive head. The stud engages with a receptacle and locks with a 90° turn, providing secure retention while allowing fast maintenance access.
