For compact project assembly, the Kreg Wood Project Clamp, 6 in. (KHC6) is the best overall pick. It adjusts to material thickness automatically, has a 6-inch reach, and accepts stock up to 5 inches thick. That makes it a practical clamp for trim, pocket-hole work, boxes, and many small-shop glue-ups.
It is not the right tool for every panel. Long, wide glue-ups call for a different clamp class. The useful choice starts with the job: holding parts together, keeping a corner steady while fastening, or securing work on the bench.
| Pick | Best for | Main tradeoff |
|---|---|---|
| Kreg Wood Project Clamp, 6 in. | Compact assembly and general holding | Not for wide panels |
| Kreg 90 Degree Corner Clamp | Boxes, drawers, and 90-degree joints | Handles material up to 1 inch thick |
| Kreg In-Line Clamp | Dog-hole bench workholding | Needs a 3/4-inch dog hole or drillable surface |
Best overall: Kreg Wood Project Clamp, 6 in. (KHC6)
The KHC6 is the sensible place to start when most of your work involves small assemblies instead of full-width panels. Kreg lists a 6-inch reach, capacity for material up to 5 inches thick, automatic thickness adjustment, adjustable pressure, and large clamp faces. Those details suit the everyday moments when you need a hand free to drive a screw, check a joint, or let glue set.
It is especially relevant for pocket-hole projects. If that is part of your process, see our beginner pocket-hole jig guide. The KHC6 works with listed Kreg pocket-hole accessories, but check the accessory instructions for your specific jig.
Who it is for: The builder making trim, boxes, small cabinets, face frames, or compact furniture parts.
Who should skip it: Anyone regularly gluing up wide panels, long tabletops, or assemblies that need more reach than a 6-inch clamp can provide.
Pros
- Automatic adjustment saves setup time when stock thickness changes.
- Large faces spread pressure across smaller workpieces.
- Adjustable pressure gives you more control than a fixed-grip clamp.
Cons
- The 6-inch reach limits the work it can cover.
- It is a compact assembly clamp, not a substitute for a set of long parallel clamps.

Best for boxes and drawers: Kreg 90 Degree Corner Clamp (KHCCC)
The KHCCC earns its place when the task is holding a corner while you fasten it. Kreg specifies it for 90-degree corners and T joints in material up to 1 inch thick. Its V and wedge pads hold the joint geometry, while the cutout leaves access for a fastener.
That makes it a useful specialty tool for boxes, drawers, cases, and small cabinet parts. It will not replace a general glue-up clamp, but it can make a two-part corner less awkward to assemble. For the next step after the box is built, our drawer slide jig guide covers a repeatable way to install the hardware.
Who it is for: The builder who makes boxy projects often enough to want a dedicated helper at the corner.
Who should skip it: Anyone working with material thicker than 1 inch, or anyone shopping for a clamp set for panel glue-ups.
Pros
- Designed for 90-degree corners and T joints.
- Fastener access means you can hold the joint while driving a screw.
- Automatic adjustment and adjustable pressure simplify repeat setups.
Cons
- It handles a specific job rather than general clamping.
- The published material limit is 1 inch thick.

Best for bench workholding: Kreg In-Line Clamp (KBCIC)
The KBCIC is for workholding, not glue-ups. It uses a peg for a standard 3/4-inch bench-dog hole and applies pressure from the side, which keeps the clamp off the top of the workpiece. Kreg also lists a 360-degree swivel, a 4 3/4-inch adjustment range, and up to 250 pounds of maximum clamping force.
That layout is handy when a bar clamp would interfere with routing, sanding, cutting, or fitting a part. You need a compatible dog-hole bench or a work surface where you can drill a suitable hole, so it is a poor fit for a plain bench with no workholding plan.
Who it is for: A small-shop woodworker with a 3/4-inch dog-hole bench who wants clear access around the workpiece.
Who should skip it: Anyone who needs a panel clamp or does not have a compatible work surface.
Pros
- Side pressure leaves the top of the workpiece accessible.
- The swivel helps the clamp meet the work at different angles.
- The compact setup stores more easily than a collection of long clamps.
Cons
- It requires a 3/4-inch dog hole or a surface you are comfortable drilling.
- It is not intended for wide-panel glue-ups.

Which clamp should you buy?
Buy the Kreg Wood Project Clamp, 6 in. if compact assembly is the job you do most. Add the Kreg 90 Degree Corner Clamp when boxes and drawers are a regular part of the work. Choose the Kreg In-Line Clamp if a dog-hole bench is already part of your shop.
Before ordering, measure the stock you use, the reach you need, and where the clamp has to sit during assembly. A clamp works best when its shape matches the job in front of it.
