Genuine Direct Source Kreg 6-in. Wood Project Clamp with Auto-Adjust Technology (KHC6) Universal

The Kreg KHC6 Automaxx 6 Wood Project Clamp is a heavy-duty clamping tool built for pocket-hole joinery. project assembly. and general woodworking hold-down tasks. This is a wood project clamp designed for holding material securely during assembly and fastening. Model Number: KHC6. With a 6 inch reach and the ability to clamp materials up to 5 inches thick. it covers a wide range of common shop and jobsite tasks without needing constant adjustment.

The big selling point here is Kreg’s Automaxx auto-adjust system. Instead of dialing the clamp in every time you switch stock thickness. the clamp adjusts automatically with a squeeze of the handles. That matters when you’re jumping between face frames. plywood panels. and thicker framing stock because it saves setup time and keeps your workflow moving. You still control the clamping pressure with a simple thumbscrew. so once you set the pressure you want. the clamp keeps that feel across different material thicknesses.

This clamp is also built to treat workpieces better than a narrow-face clamp. The large clamp pads spread pressure more evenly across the contact area. which helps reduce denting and surface marks on finished or softer materials. If you’re doing glue-ups. cabinet parts. or pocket-hole joinery where alignment matters. that wider contact patch gives you a steadier hold without concentrating all the force in one small spot.

Kreg built the KHC6 with all-metal construction for durability. which is what you want in a clamp that gets opened. closed. tossed on the bench. and used hard over time. The padded ergonomic grips are not just a comfort feature on paper. They make a difference when you’re doing repeated clamping during assembly work. especially on longer bench sessions where hand fatigue starts to show up fast with bare metal handles.

In practical use. this 6 inch clamp is a good middle ground for woodworkers and installers who need more reach than a small specialty clamp but still want something quick to position. It is rated for up to 450 pounds of clamping strength. giving it enough holding power for common woodworking assemblies and drilling operations. At the same time. the automatic adjustment keeps it from feeling fussy or overcomplicated.

The Kreg KHC6 Automaxx 6 Wood Project Clamp also fits into the Kreg joinery system. It works with the Kreg Pocket-Hole Jig R3 Clamp Pad Adapter. 300-Series Pocket-Hole Jigs. and the Kreg Portable Base. If you already use Kreg jigs. that compatibility is a real advantage because the clamp can move from general bench work to jig-based fastening without needing a separate dedicated hold-down.

This clamp makes the most sense for woodworkers. cabinet builders. finish carpenters. and serious DIY users who want fast setup and repeatable holding pressure. If you do a lot of pocket-hole assembly or move between different stock sizes all day. the automatic adjustment is the feature that earns its keep. If you only clamp one material size once in a while. a basic clamp can work. but this one is clearly aimed at users who value speed. consistency. and less fiddling.
