The Kreg Tool KT1024-200-25 MortiseMate 10mm Loose Tenons (25-Pack) is a hardwood loose tenon joinery accessory built for strong, repeatable wood joints. This is a loose tenon joinery accessory designed for joining wood parts with 10 mm mortises. Model Number: KT1024-200-25. If you are building furniture, cabinets, casing, or other assemblies where alignment and joint strength matter, these tenons give you a ready-to-use option without having to mill your own stock.

What matters here is fit. These tenons are designed for use with 10 mm diameter mortising cutters, so they are sized to drop into the mortise correctly and help keep parts aligned during glue-up. That makes assembly easier, especially when you are dealing with rails, stiles, face frames, or narrow parts where a sloppy fit turns into extra clamp time and extra cleanup.

Kreg builds these from all-natural solid hardwood, which is the right material choice for this kind of joinery. Hardwood gives the tenon the strength and stability needed to reinforce the joint instead of acting like a filler piece. In practical use, that means better resistance to movement and a more dependable connection than a weak or inconsistent insert. The fluted shape also is not there just for looks. Those flutes give glue somewhere to go, helping spread adhesive through the joint instead of hydraulic-locking the parts before they seat fully.

Another smart detail is the length allowance. Kreg states these tenons are made approximately 1/16 in. shorter than nominal length so there is room in the mortise for glue. That is one of those small details that saves headaches on the bench. You get space for adhesive without forcing squeeze-out to push the parts apart, which helps the joint close more cleanly during assembly.

For storage and consistency, the pack comes in a resealable container. That matters more than it sounds like it should. Loose tenons are wood, and wood movement is real. A resealable container helps reduce expansion and shrinkage between uses, which gives you more consistent fit from the first tenon in the box to the last one left on the shelf.

On compatibility, these are specifically meant for 10 mm mortises and are noted as compatible with the Kreg MortiseMate Loose Tenon Jig. If you are already using that system, this is the straightforward refill. If your setup cuts a true 10 mm mortise with the right geometry, these are the size to look at. The listed dimensions are 10 mm x 24 mm x 2 in., giving you a tenon with a 10 mm thickness, 24 mm width, and 2 in. overall length.

Who should buy these? Woodworkers, cabinet installers, trim carpenters, and serious DIY builders who want the speed and alignment benefits of loose tenon joinery without making their own tenon stock. If you are already set up for MortiseMate work, these are the convenient shop consumable that keeps the process moving. If you are chasing clean alignment, dependable glue joints, and less setup at assembly, this is exactly the kind of accessory that earns its drawer space.
