Slotted and Cross Slotted Drives
Slotted and Cross Slotted Drives
Slot screw drives have a single slot in the fastener head and is driven by a blade or flat-bladed screwdriver. Historically It was the first type of screw drive as it was easy to cut a saw slot into the screw. and for nearly 1000 years it was the simplest to make.
The slotted screw is popular in simple hand woodworking applications, but is not often seen in applications where a power tool would be used because a power driver bit tends to slip out of the head, damaging the surrounding material and potentialy the person using the power tool.
