The Moroso flush-head quick fastener is an aluminum 5/16in shank with .500in length, sold as a 10-pack for applications needing a flush finish and extra shank length. The aluminum body reduces weight and the extended reach suits thicker panels or stacked assemblies while maintaining a low-profile surface for a tidy installation.
