The design of the Key Clamp system makes constructions a straightforward task with no requirement for specialist tooling. Key Clamps are used in conjunction with galvanised steel tubing. The Key Clamps are secured to the tube by means of hexagon socket set screws, which are tightened using an allen key or ratchet spanner to establish a firm lock between the clamp and the tube. The sharpened edges of the socket set screws effectively 'bite' into the surface of the tube creating a solid connection. Key clamp fittings are blackheart malleable iron castings manufactured to the requirements of BS EN 1562 1997 and are hot-dipped galvanised to BS EN 1461:1999 and are supplied with pre-fitted socket set screws (aka 'grub screws'). When tightened to 4.1kg (29 ft/lb) a slip load of 900kg can be achieved on each screw. There are many standards and regulations which are applicable to many common uses of Key Clamps. Please contact us with any questions that you may have. Key Clamps are supplied in a galvanised finish. We also offer a powder coating service through which the Key Clamps and / or tube can be supplied in a RAL colour of your choice. When applied to a galvanised finish, powder coating provides a long lasting, low-maintenance and colourful finish ideal for a multitude of applications (please contact us for more information regarding this service).
