Key Features
Auto-adjust clamping Set it once and clamp different thicknesses without re-dialing the jaw every time. Faster box builds, cabinet work, and glue-ups. Thumbscrew pressure control Fine-tune clamping force with a simple thumbscrew so you can lean on it for joints or back it off for delicate stock. Comfort that lasts Ergonomic padded grips help reduce hand fatigue when you are clamping repeatedly during assembly.
Overview
The Kreg KSC16 Auto-Adjust Bar Clamp – 16 inch (Model KSC16) is a bar clamp built for quick, repeatable clamping during woodworking assembly. This is a bar clamp designed for holding parts tight and square during glue-ups and fastening.
The big advantage is the auto-adjust mechanism. Once you set the clamp, it automatically adjusts to changes in material thickness so you are not constantly moving the head to chase fit. That is a real time-saver when you are bouncing between parts like face frames, cabinet boxes, and drawer assemblies.
Clamping pressure is easy to control with a simple thumbscrew. Crank it up when you need firm pressure for joints, or back it off when you are working on softer woods or pre-finished material and want to avoid marking.
Capacity is the other reason to grab this one: it clamps material up to 16 inches thick with a 1 1/2 inch reach. That reach is right where you want it for edge work and case assembly without the frame getting in your way.
The extra-large clamp faces help spread pressure more evenly across the work, which is especially helpful on plywood edges and assembled boxes. Pair that with the padded grips and you get a clamp you can cycle all day without beating up your hands.
It is built with a highly durable, all-metal construction for jobsite and shop use. If you have ever snapped a plastic clamp handle mid-glue-up, you already know why that matters.
This clamp makes the most sense for woodworkers, remodelers, and serious DIYers who want a fast assembly clamp that stays consistent from part to part. If you do repeatable cabinet or furniture work, the auto-adjust feature is the difference between “pretty good” and “why didn’t I buy this sooner.”
Faster Box and Case Assembly
Use it as a third hand when you are building boxes, cabinets, and drawers. The clamp holds alignment while you drive fasteners or let glue set.
- Auto-adjust technology adapts to different stock thicknesses without re-setting the jaw
- Extra-large clamp faces help spread pressure more evenly across the work
Dial In Clamp Pressure
Not every job needs maximum squeeze. The thumbscrew lets you set pressure for the material and the task so you can clamp confidently without crushing or shifting parts.
- Easy-to-regulate clamping force using a simple thumbscrew
- Ergonomic padded grips help reduce hand fatigue during repeated clamping

Pro Tip
When you are clamping plywood boxes or pre-finished parts, start with lighter thumbscrew pressure and add only what you need to close the joint. You will get a tighter-looking assembly with less chance of denting the edges.

Auto-adjust saves you time, and the thumbscrew lets you choose “firm” or “gentle” depending on the work.
- Who it’s for: Anyone doing repeated woodworking assembly, cabinet boxes, drawers, and furniture builds.
- Why it stands out: Auto-adjust clamping plus easy pressure control makes it faster than a basic F-style clamp for repeat work.
- Worth knowing: The 1 1/2 inch reach is great for edge work and boxes, but it is not meant for deep reach clamping.
