Quarter Turn - DA-4600 Line
With a quarter turn stud rotation; the DA-4600 Line studs engage sloped cams in the receptacle and lock into a dead-end detent. Cam action pulls the bottom of the receptacle up against spring tension. Arrival at the locked position is obvious due to an over-rotation stop and a detent snap action that can be felt.
Manufactured from lightweight, high strength thermoplastics, the DA-4600 Line quarter turn fasteners provide a modern, stylish finish coupled with the advantages of quick access and low installed cost.
The fasteners lock with a vibration-resistant clamping tension, cannot be overturned, and may be operated thousands of times.
Installation is fast and secure. Studs may be held with push-on retainers or pushed through molded one-way holes. Receptacles may be riveted or snapped into rectangular holes from above or behind.
The evident quality experienced with DA-4600 Line fastener operation will reflect well on the products which use them.
