Thumb screws offer a hand-adjustment feature,which allows for simple action to fasten, tighten, loosen, or remove thescrews. However, they are also ideal for applications in which space is toorestricted to allow enough clearance for the use of tools to fasten the screw.

Designers might choosethumbscrews for household, electronic and other consumer products, not just forthe ease of fastening but also to avoid the risk of over-tightening. They areparticularly beneficial for assemblies that require repeated removal andreinstallation.

When used forremoval-and-reinstallation applications, such as safety covers or accesspanels, these bolts can reduce the amount of time required for maintenance orinspection. Their hand-adjustment design also reduces the incidence of brokenor stripped fasteners that might occur with frequent removal andreinstallation.
