Moroso Self-Ejecting Fasteners

4.03 out of 5 stars 31 Customer Reviews

Moroso self-ejecting fasteners are spring-loaded and guarantee a quick release. Perhaps more importantly, the built-in spring holds the locking button captive so that it can't be dropped underneath the car or fall into some hard-to-get-at area of the chassis. They're available in a range of sizes to handle a wide variety of fastening situations. They are an absolute "must" for quick pit work in just about any kind of racing, including drags, oval track, off-road, rally, and road racing.
