Barrel Nut Bolt

This is a strong and positive fitting for all types of frame construction where the end of a rail meets the side of a leg or other vertical member. The bolt passes through a counterbored hole in the leg and into the end of the rail, where it is then screwed into a threaded barrel nut located in a stopped hole. A screw slot in the end of the nut allows vou to align the threaded hole with the bolt. A wooden locating dowel fitted in the end of the rail makes assembly easier and prevents the rail from turning as the bolt is tightened.

3 Fitting the locating dowel

Tap a panel pin into the end of the rail on its centre line, about 12mm (1/2in) from one edge. Crop the head off the pin, then assemble and tighten the fitting. Dismantle the joint, and drill a 6mm (Vm) stopped hole in the leg where the cropped pin left a mark. Remove the pin and drill the rail in the same way as the leg, then glue a short dowel in the hole.

1 Drilling the rail

Draw diagonals across the end of the rail to find the centre, and bore a clearance hole for the bolt where the lines cross. Calculate the distance from the end of the rail for the barrel nut, and drill a stopped hole in the side of the rail to intercept the bolt hole.

TEE NUTS AND BOLTS

A tee nut is an internally threaded collar with an integral spiked washer that provides a firm anchor for a bolt fixing. A relatively crude fitting, it is probably best reserved for upholstered frames.

Fitting a tee nut

Clamp the components together and drill an 8mm (5/6in) clearance hole through both parts. Tap the nut into the back of one component and pass the bolt through the other. Tighten the bolt to pull the parts together, and seat the nut securely in the wood.
