These standard 10-24 set screws are used with vintage style knobs mounted on straight, tapped spindles. The screw slides through the knob and turns directly into the threaded hole on the spindle (not to be confused with headless set screws used for tightening knobs onto threaded spindles). The set contains enough screws to mount four knobs onto spindles. Made of brass-plated steel.
These are a #10 screw, 3/8" in length, with 24 threads per inch.
