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 our range of Slotted Screwdrivers or Slotted Drive Bits.

Materials

Maximise the performance of your Fillister Screws with Accu’s pre-applied thread-locking patches, designed to prevent loosening caused by vibration. Choose AccuLock Threadlocker for fundamental security, Anu-Lok 180 for superior strength, or Precote 80 for extreme conditions. Customise further with AccuBlack chemical blackening, delivering a high-end, low-glare finish.

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.
