Knurled Thumb Screws - Slotted/Plastic

In stock

Knurled Thumb Screws, often simply referred to as Thumb Screws or a Knurled Screw, are among the most commonly used screw types and are highly important. This is due to their versatility, as they can be used across a plethora of industrial applications.

These Nylon Thumb Screws can be fastened manually; they are made for applications that need regular modification, because they are easy to install and remove. They can also be installed using a flat head screwdriver. Made from Natural Nylon 6/6, they have a knurled head that features a slotted drive.

As well as M4 Thumb Screw options, our Nylon Thumb Screw range also has M3, M5 and M6 thread size availability.
