This is a set of 5 used gib screws that fit the Jet/Powermatic planers. These are in excellent shape and will work as good as new ones. This screw works in the 15", 16", and 20" planers. The thread is 8mm x 1 pitch. They are 15mm long and have a 12mm head. These will probably work on all of the other import machines also. When the heads round off it's time to swap them out or you'll have a stuck screw. Plus, when the screws round off they ruin the wrench. Shipping on this item is free via USPS or UPS.
