Thumb screws offer a hand-adjustment feature, which allows for simple action to fasten, tighten, loosen, or remove the screws. 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.
Designers might choose thumbscrews for household, electronic and other consumer products, not just for the ease of fastening but also to avoid the risk of over-tightening. They are particularly beneficial for assemblies that require repeated removal and reinstallation.
When used for removal-and-reinstallation applications, such as safety covers or access panels, these bolts 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.
