Slotted Thumb Screws or Slotted Knurled Knob Screws are designed primarily to be tightened and loosened by hand, without the need for a screwdriver or ratchet, but this version comes with a slot in the head for a standard slotted screwdriver. The 'knurled' feature of the head makes this type of screw ideal for use where conditions can be challenging such as food preparation or clean room operations. Manufactured to DIN 465.

This is the thin type of knurled thumb screw, as it has no shoulder beneath the head, unlike the high type of thumb screws. The large head diameter allows these fasteners to be easily adjusted to a precise tightness by hand. They are frequently used in situations where routine maintenance is required, as they are quicker and easier to fit and adjust in comparison to fasteners which require a driver.
