Versatile and Reliable Clamping for Everyday Woodworking

F clamps are indispensable tools for both beginner and professional woodworkers. Their design, featuring a sliding arm on a fixed steel bar, makes them ideal for a wide range of clamping tasks, from holding components during assembly to applying pressure during glue-ups. Known for their speed, ease of use, and reach, F clamps are a go-to solution in any woodworking shop.

These clamps provide strong, adjustable pressure and are especially useful when working on projects with irregular shapes or tight spaces. Their slim jaws can reach into awkward positions, and the bar length allows for variable clamping widths.

Purchasing different sized F Clamp sets enables users to match the clamp size to the job without compromising on pressure or stability. F clamps are particularly effective for light to medium-duty applications, such as joining boards, holding jigs, or securing material to workbenches.

When using F clamps, it’s important to position them evenly across the workpiece to prevent twist or uneven pressure. Protect delicate surfaces with scrap blocks or jaw pads, and tighten gradually to avoid over-compression. Regular maintenance involves wiping down the bar to remove dust and glue buildup, and occasionally lubricating the screw threads to keep the mechanism smooth and responsive.

FAQs


How do F clamps differ from parallel clamps?

F clamps have thinner jaws and a lighter frame, making them easier to manoeuvre for quick clamping tasks. Parallel clamps, on the other hand, offer more precise alignment and consistent pressure over a wider area, which is better for panel glue-ups and squaring assemblies.

Can I use F clamps for heavy-duty clamping?

F clamps are best suited for light to medium clamping pressure. For heavy-duty applications, such as large panel glue-ups or structural joinery, bar clamps or pipe clamps may be more appropriate due to their greater clamping force.

What sizes of F clamps should I have in my workshop?

A good starting set includes clamps ranging from 150mm to 600mm. Larger clamps can handle wider materials, while smaller ones are useful for tight spaces and quick setups. The more variety you have, the more flexibility you'll gain for different projects.

Do F clamps damage wood surfaces?

They can if used without protective pads or scrap blocks. To avoid denting or marking your workpiece, place thin timber offcuts between the clamp jaws and the surface of your project.

How much pressure can F clamps typically apply?

Most quality F clamps can apply between 150kg and 500kg of clamping force, depending on their size and construction. Heavy-duty models may offer more, but for most woodworking tasks, this range is more than sufficient.

How do I maintain my F clamps?

Keep the steel bars clean from glue and sawdust. Lubricate the screw mechanism occasionally and check for any misalignment or wear in the jaws. Proper storage—hanging or in racks—will prolong their lifespan.
