Challenge (Europe) - handles, clamps, machine parts, stud rivets, valve knobs and captive screws

Along with threaded fasteners goes a whole swathe of ancillary products which, for the team at Challenge (Europe) are characterised by items such as instrument handles, clamp screws, stud rivet assemblies, valve knobs, captive screws and a great capability in the production of custom specialist machined parts.

This capability covers most metals and sometimes plastics with non-standard special items to customer drawings or non-standard sizes to international standards, e.g. an intermediate diameter or length. Where an ex-stock item is not suitable they are happy to advise.

Instrument carrying handles in painted or chrome finish are suited to instruments, trollies, cases etc.

Clamp screws are designed to suit specific customer requirements for the clamping of components by hand operation rather than for screwing into a component. They can be manufactured in steel, stainless steel, brass, and to many sizes metric and imperial. Stud rivet assemblies provide a quickly installed permanent rivet nut type of assembly but with a re-usable male screw thread. Used mainly in sheet material where accessibility or other installation processes, e.g. welding, are not practical options.

Valve knobs are just one example of a product resulting from a joint customer development project.

Captive screws are another example – they are retained by means of having a reduced diameter shank following on from a standard screw thread – usually with a raised head for tool or manual operation. Standard metric sizes, materials plated steel or stainless steel. This is one style of fastener which is often required to custom dimensions as they must be a correct length to suit the application.
