About this deal

A thumbscrew is a type of screw drive with either a tall head and ridged or knurled sides, or a key-like flat-sided vertical head. They are intended to be tightened and loosened by hand, and are usually not found in structural applications. They are sometimes also cut for Phillips head or slotted screwdrivers, as well as having the knurling for finger grip. ASME Standard 18.6.8 covers dimensions for Type A (shoulder under the head), regular and heavy, along with Type B (without shoulder), regular and heavy. They can be found on many computer cases, and in other locations where easy access without tools is desired. As a relatively new owner just exiting warranty on our '12 JSW, it's time to tool-up.

This form was the first type of screw drive to be developed, and for centuries, it was the simplest and cheapest to make because it can just be sawed or filed. Additionally, it is unique because the slot head is straightforward to manufacture, and because it can be driven by a simple handtool. The slotted screw is commonly found in existing products and installations, along with use in simple carpentry work and in applications where minimal torque is needed.
