Lift-The-Dot Fasteners are a locking fastener that locks on three sides to prevent unintentional unfastening. When pulled from the fourth side, the fastener easily lifts free. Perfect for marine applications, these fasteners can be used to secure boat covers and tops. These Lift-The-Dot Studs are equipped with a Size 8-18 Stainless Steel self-tapping screw. Self-tapping screws form threads when installed, so no pre-drilling is required.
