About Us
Machined in Wisconsin. Built for the jobsite.
Keepfast makes tool and battery storage in a small machine shop in Burlington, Wisconsin. Our mounts fit Milwaukee M18 and DeWalt 20V cordless tools and give them a solid, permanent home in your shop, truck, trailer, or van.
How we make them
Every holder starts as a solid block of 6061 aluminum and is CNC-machined in our own shop. It's not 3D-printed or molded plastic. After machining, each part gets a black Type II anodized finish that resists corrosion and holds up to daily use.
- Solid 6061 aluminum: strong, light, and won't crack like plastic.
- Precision fit: tools and batteries slide on just like they do on the real thing. Batteries latch in on their own, and a retention clip locks tools in for any orientation.
- Mounts anywhere: wall, shelf, bench, pegboard, or vehicle, with standard countersunk screws.
- Made in the USA: designed, machined, and shipped from Burlington, WI.
Our promise
We stand behind what we make. Every order comes with a 30-day return policy and a lifetime warranty. If a holder ever breaks under normal use, we'll replace it.
