Slotted Fillister Head Machine Screws
Slotted Screws for Counterbored Holes
Slotted Fillister head machine screws have a large over sized head and are used to attach metal to metal or metal to wood. A Fillister head machine screw, sometimes called a cheese head screw, is similar to a Pan head machine screw but with greater side height. Fillister head screws are the preferred head type for counterbored holes.
