Discover more about the Fillister Screws range.

Fillister Screws are part of Accu's extensive range of Precision Screws. These fasteners are an imperial component, featuring a reduced diameter cylindrical head, which allows them to be used in applications where space is limited. Fillister Screws have an increased head height and a deeper drive slot when compared to equivalent round-headed fasteners such as Cheese Head Screws. These fasteners are widely used in electrical applications.

Components within this range can be installed using one of AccuScrews’ Insulated Slotted Screwdrivers or Slotted Drive Bits.

Materials

These A2 Stainless Steel fillister screws can be ordered with Chemical Blacking and Thread Locking Patches on request. For additional materials and finishes, please contact our sales team.

Imperial Fillister Screws

Fillister Screws are available in diameters of between #0 and 3/8 inch, and in lengths ranging from 1/8 inch up to 6 inch.
