Product Characteristic

1. Knurled thumb screws offer a hand-adjustment feature, which allows for simple action to fasten, tighten, loosen, or remove the screws. The main benefit is that no tools are needed, so assembly teams and end-user consumers can adjust the screws with thumb and forefinger alone.

2. Thumb screws are used almost exclusively for the purpose of simplicity. However, they are also ideal for applications in which space is too restricted to allow enough clearance for the use of tools to fasten the screw.

3. When used for removal-and-reinstallation applications, such as safety covers or access panels, thumb screws can reduce the amount of time required for maintenance or inspection. Their hand-adjustment design also reduces the incidence of broken or stripped fasteners that might occur with frequent removal and reinstallation.

4. Thumb screws are not recommended for structural applications or high-vibration environments, such as automotive, railway or marine vehicles, where cyclical loading might cause them to become loose over time.

Product Benefits

1. Knurled thumb screws have a specially designed head that makes it easy to turn with one hand and ideal for use on parts that are frequently used such as an access panel. 

2. These easily gripped heads have wings, ridges, or protruding tips for tightening by hand. Stainless steel screws are good for exterior applications as they are naturally resistant to corrosion.

3. Knurled head standard thumb screws fasten panels on electronics and other frequently accessed devices. 

4. They are installed by twisting the fastener into predrilled or tapped holes. These thumb screws are fully threaded with no shoulder and have a ridged, flat, or hex socket head.
