Custom Spec & Build to Drawing
Send a drawing, a sample, or even a photo from the job site. We reverse-engineer it and quote in 24 hours.
Overview
How it works
A surprising share of enquiries start with a screw in a padded envelope and no paperwork at all. Somebody's supplier discontinued a line, or a machine was built in 1994 and the fastener was never documented. That is a normal starting point for us.

What you get
The detail that matters
From a drawing
Dimensioned drawings are quoted directly. Tell us which standard governs — DIN, ISO, ANSI or your own — and the inspection report follows it.
From a physical sample
Samples are measured in our own laboratory: dimensions, hardness, thread form and finish.
From a photograph
A clear photo with a scale reference is often enough to identify the family and start the conversation.
Sample before tooling
For new specifications we ship physical samples for your approval before tooling and production — within 5 working days of approval.
