Knock Down Joints

Mr BILLINGTON

Knock-down (KD) fittings & fixings are designed to be a temporary joining method between two materials which can be removed without damaging the material surfaces. They are commonly found in flat-packed furniture where the customer is required to assemble the product after purchase and allow for the disassembly for end of use or relocation

KD fittings are designed to require basic tools commonly found in most homes and often supplied with specific tools if required. Commonly, screwdrivers, allen keys, spanners & hammers can be used to assemble a range of KD fittings making them easily accessible to the customers without a wide range of tools/equipment

All KD products are supplied with a step-by-step graphical instruction manual that removes the need for a technical knowledge of the product. Each step references a different tool or fitting with detailed assembly views of the process in an appropriate 3 dimensional angle. Parts are referenced throughout with codes and relate directly to a parts list at the start of the instructions

There are a number of fittings & fixings suited to different applications to form temporary joints between parts, whilst maintaining strength;

Connecting Block - injection moulded plastic blocks, typically Polyethylene, that are used to ensure a right angled joint between two parts. They often have 3 fixing holes for bolts or screws and are easily removed without damaging the surface of the material

Furniture Bolts - threaded steel bolts, commonly with a flat head and hexagonal cutout. They are designed to be tightened into a female thread embedded in the furniture using an allen key, typically M4, and included with the product

Cross Dowels - also known as 'barrel nuts 'used with joint connector blocks provide the female thread for furniture bolts. They can easily be inserted into parts using a drilled hole from a CNC router and are located to align with the bolt using a flat head screwdriver

CamLock Fitting - use a smooth bolt with a screw thread at one end to secure it into the material & a screw head at the other. The head of the bolt is designed to slot into a recess in a metal cam which is twisted to pull the workpieces flush together. An arrow on the cam communicates the location of the recess & rotation direction

Confirmat Screws - are designed to screw directly into particle board using a long tapered shaft. They form a strong bond between longer right angled sections and the deep cutting thread helps to ensure accurate, close-fitting joints

Cover Caps - polymer caps designed to clip into the end of bolts and screws in order to conceal them on the product. They are injection moulded and available in a range of colours and finishes to fit different head profiles
