Chipboard Fasteners

You can improve the strength of screwed joints in chipboard by fitting nylon inserts into the square-cut edges. These chipboard fasteners plug into pre-drilled holes and expand to grip the material as the screw is tightened.

Square Cut Edges

1 Marking the panels

Cut the boards square and, using a marking gauge, scribe a centre line on the end of one component. Depending on the width of the boards, mark off two or more screw centres. Mark matching centres on the face of the other component.

Butt Joint Fastners

2 Making the joint

Bore screw-shank clearance holes through the side panel, and larger stopped holes for the nylon fasteners in the edge of the other component. Countersink the clearance holes, if necessary, then insert the fasteners and assemble the joint.

SCREW CONNECTORS

Butt Joint Fastners
These bright-galvanized or black-finished screw fittings have coarse threads that make secure butt joints without inserts. The shallow, countersunk heads are cross-slotted or have a hexagonal socket that is driven with a cranked kev.
Panel Clamping Jig

1 Drilling stopped holes in the edge

A special jig holds the drill bit perpendicular to the surface. Mount the jig on the end of the horizontal component and align it with screw centres marked across the workpiece. Clamp the jig, and drill stopped holes for the threaded screw shanks.

Carcase Drill Jig

2 Drilling clearance holes

Clamp the jig over the end of the upright component, aligning it with similar screw centres. Bore clearance holes through the panel, using the boss on the side of the jig to guide the drill bit. Screw the joint together -only hard plastic-faced materials need countersinking.

SCREW SOCKETS

Picture Frame Joint Fasteners

Threaded-metal screw sockets provide secure fixing points for bolting together wood frames or man-made boards. A coarse thread on (he outside of each fitting pulls the socket into a stopped hole drilled in the face of one component. A finer thread on the inside of the fitting receives a metal bolt that holds the other component in place.

Metal Fasteners For Aligning Wood

1 Fitting a socket

Bore an 8mm (5/i6in) diameter stopped hole deep enough to set the socket just below the surface of the workpiece. Drive the fitting into the hole, using a screwdriver in the slot cut across the end of the socket.

2 Assembling the components

Mark the centre of a clearance hole for the bolt in the other component and drill right through it, taking care not to splinter the wood fibres on the underside. Assemble the two halves of the joint, clamping them tightly with the bolt.

BLOCK JOINTS

Interlocking Plastic Joint

This inexpensive, surface-mounted fitting consists of interlocking plastic blocks screwed on the inside of cabinet corners. Moulded dowels on one half of the joint locate with sockets in the other. When two panels have been joined at right angles, the block fittings are clamped together with a bolt.

Small Right Angle Fasteners

1 Fitting the socket blocks

Mark the thickness of the board on the inside of the carcase side panel. Mark the positions of two block joints about 50mm (2in) from the front and back edges. Align the base of each socket block with the marked lines, and screw it to the panel.

2 Fitting the dowel blocks

Holding the panels together at right angles, fit the mating dowel blocks and mark their fixing holes on the other board. Screw the blocks in place, and assemble the joint with the clamping bolts.
