What it is

The WETOLS 90 Degree Corner Clamp Set is a practical solution for hobbyists looking to simplify the assembly of boxes, drawers, and picture frames. Constructed from high-strength polyamide, these clamps utilize a spring-loaded mechanism to hold boards between 3/16 inch and 3/4 inch thick in place. While they are not intended for heavy industrial metalwork, they excel at keeping wooden workpieces aligned for hands-free fastening or gluing.

Ravvy AI insight

These clamps are best used as an extra set of hands rather than a high-pressure compression tool. For the best results, ensure your wood is cut precisely at 45 or 90 degrees before clamping, as the spring tension is designed for alignment rather than forcing warped boards into position.

How to get the most out of it

Optimizing T-Joints

When creating a T-joint, place the perpendicular board in the clamp first to ensure the spring tension is evenly distributed before adding the side board. This prevents the pieces from sliding out of alignment during the initial bite.

Ownership tips

care

Maintaining Spring Tension

Avoid storing the clamps in an open position for long periods. Keeping them closed when not in use helps the internal springs maintain their original tension and prevents fatigue in the polyamide frame.

tip

Use with Glue

Apply a thin layer of wood glue and let it get slightly tacky before clamping. Because these are spring-loaded rather than screw-tightened, this prevents 'hydroplaning' where the boards slide against each other under pressure.

Frequently asked questions

Can these clamps hold two boards of different thicknesses?

Yes, the spring-loaded head automatically adjusts to accommodate boards of different widths simultaneously. As long as both boards are between 3/16 and 3/4 inches thick, they will stay aligned.

Are these suitable for welding?

These are made of polyamide, which is a type of plastic. They are intended for woodworking and would likely melt or be damaged by the heat and sparks generated during welding.

How much pressure do these apply?

These provide moderate pressure suitable for holding pieces in place while you drive a screw or nail. They do not provide the high-intensity compression found in F-style or pipe clamps.

Will they leave marks on soft wood like pine?

The polyamide material is much softer than steel, which significantly reduces the risk of marring. However, for very soft woods, you can always place a small piece of painter's tape on the contact points.
