The bag contains 50 bolts, an allen key and a drill bit to create M3 size holes. With these items and a drill you have all the items to fasten two beams without a bracket on the outside. It offers you an infinitely adjustable blind fastening method. This product works well with our 15x15mm profiles (MakerBeamXL and OpenBeam).

Place a bolt in the M3 threaded hole on top of a beam. Drill a hole in another beam with the drill bit in the bag. Slide the fastened bolt in the second beam that has the hole. Place it in so the bolt is in front of the drilled hole. Place the allen key in the hole and use it to fasten the bolt.
