Product Information

Thumb screws and thumb screw bolts can also be useful solutions in a situation where you may need to remove a component or panel regularly. To choose the best thumb screw for the task, it is important to bear in mind certain characteristics such as length, diameter, and thread size.

Small thumb screws can be as short as 4mm or less from the shoulder to the end of the threading, while long thumb screws commonly extend to around 25-30mm (1 inch) and beyond.

Several options available; the first two options offer easy assembly with bolts and nuts, with a single hammer-stroke. Knurled thumb screws are commonly chosen because they give the user a better grip on the head of the fastener when installing by hand.

This tends to imply that the product would need to be more rigid (less range of deflection) and have greater tensile strength than most of these relatively small fasteners tend to offer. One of the main reasons why thumb screws are often chosen over traditional screws is that certain parts and assemblies do not leave much room for using hand tools. A true thumb screw or bolt can be distinguished from standard bolts or rivets by its large head, offering easier grip.
