InkleinD Screws with No Slot

What happens here

InkleinD offers screws with a unique 'no-slot' design for a clean, seamless finish. A special driver tool is used to apply pressure to the top of the screw, which then reveals the slots for insertion. This design prevents damage to the screw head when torquing and results in an aesthetically pleasing unbroken surface. InkleinD also creates other innovative woodworking products like geared twin-screw vises. Their products are available on their website, InkleinD.com.
