An F-clamp is designed in the shape of a letter ‘F’. The tool consists of one long, vertical bar and two horizontal jaws.
In many ways it works similar to a G-clamp because one jaw is fixed at one end of the bar, whilst the other is moveable and can slide into different positions.
It differs to a G-clamp, however, as the jaws can open a great deal wider.
Its strong construction makes it the ideal tool to use for heavy-duty woodworking, as it can withstand the pressure that comes with clamping large and heavy workpieces.
The shape of an F-clamp means it is often used by DIYers for gluing workpieces together, as its wide jaws and straight frame can hold two objects perfectly parallel while the glue sets.
A number of F-clamps can be used during one gluing application to equalise the pressure along the length of the workpiece.
