Custom fasteners

With more than 40 years’ experience, Blue Diamond already provides a single UK source offering global procurement of special parts and is now widening this service to supply custom fasteners with complex or unusual geometries in low batch quantities – typically 500 upwards. 

The company says custom fasteners are manufactured using hot and cold forging techniques at a fraction of the cost normally incurred to machine them from scratch. This includes fasteners with eccentric heads, unusual head forms or recesses, captive washers, and with features such as thread-locking compounds and nylon inserts. Where required, further details can be added using secondary machining processes. 

Examples of components already supplied by Blue Diamond include bolts and fixings with hexagonal socket, flanged, triple square, double hex, and hexalobular head forms. Nuts can incorporate flanges, castellations, self-locking features and captive washers.

Parts can be supplied in a wide range of materials including carbon and alloy steels, stainless steels and non-ferrous metals. Heat treatment is available to achieve enhanced mechanical properties as needed.
