Custom Fasteners to Drawing

Where no published standard fits, the drawing becomes the specification.

The starting point is your drawing, not our catalogue

JIS, ANSI, DIN, BSW, GB, ISO, BS and IFI are all held, and most enquiries resolve to one of them. When they do not — a special head profile, a thread form that is not on the standard list, a length outside the usual range — we work to the customer's drawing or sample rather than offering the nearest catalogue part and hoping it is close enough.

What we need to quote a special

A dimensioned drawing, or a sample and the dimensions that matter on it; the material and property class; the finish, or the exposure it has to survive; and the quantity. If any of those is still open, say so — a quotation against an assumption is worth nothing to either side.

The range a special can sit inside

Diameters from M0.8 to M42 and lengths from 2mm to 3000mm, in mild, medium carbon and alloy steel, stainless SUS201 through 430, brass and aluminium.

The enquiries worth sending are the ones where the catalogue does not obviously answer the question. Send the drawing, the sample or the failure you are trying to design out.
