Hold-Down Fixture Clamps
Tighten these clamps to hold your workpiece from above. They’re also known as swing clamps, since you can rotate the hook out of the way when the screw is loose. Install them in a drilled hole for maximum rigidity.
Clamps with a socket head screw are a good choice when you have limited vertical clearance. The screw is mounted nearly flush with the top of the clamp.
Clamps with a cap nut tighten and loosen by hand, so you don’t need tools.
Add mounting blocks to rotate the clamp’s hook consistently—these blocks have a stop every 90°. They’re also useful if you don’t have an easy mounting location for the fixture clamp.

Hold-Down Fixture Clamps with Handle
Turn or flip a handle to secure or release your material—no tools required. These clamps are easier to set up than other hold-down clamps, so they’re good for frequently swapping fixtures or using multiple clamps at once. Also known as swing clamps, they have a rotating clamping arm that can be moved out of the way when the clamp is not engaged.
Adjustable handles turn left and right to clamp and release. After engaging the clamp, you can pull the handle straight up to move it out of the way. You'll feel the handle disengage—that means you can rotate it freely while maintaining your clamp.
Cam handles flip down to clamp and up to release, so it’s easy to see if your material is secured.
Lever handles clamp with a turn to the left or the right.

Light Duty Fixture Clamp Kits
Made of plastic, the clamps in these kits are used for woodworking and other machining jobs that don’t need high clamping pressure. Each kit comes with edge guides and three different types of clamps, so you can secure workpieces of all shapes and sizes. Edge guides are often used as a frame to consistently position multiple workpieces for repeat jobs. Ring fixture clamps tighten with a twist—they press into the side of your workpiece to hold it in place. Side clamps apply force both inward and downward without blocking the top of your workpiece. Hold-down clamps grip the top and side of your workpiece for the most secure hold.
