Mounting plates are simple parts with one requirement that matters: every hole has to line up with whatever bolts to it. We plasma cut the blank to size, then drill, tap, countersink or slot the holes to your drawing, so the plate goes on without opening holes out on site.
Tapped holes mean you can bolt straight into the plate without nuts behind — useful where you can't reach the back face. Slotted holes give you adjustment for belt tension, alignment or tolerance stack-up.
Typical mounting plates
Motor and gearbox mounting plates; pump and fan mounting plates; adapter plates between two bolt patterns; control and instrument plates; and fixing plates for frames, rails and enclosures.
Choose mild steel for general use, stainless for wet or washdown areas, or aluminium where weight matters.

How to order
Send your drawing (DXF, DWG or PDF) or a dimensioned sketch with the material, thickness and quantity. We'll check it, ask about anything unclear, and reply with a price and lead time. Once approved, parts are made in our Knowsley workshop for collection or UK delivery.
Questions we're often asked
Which thread sizes can you tap?
Common metric threads. Small threads such as M4 may be drilled and tapped as a secondary operation — list the sizes on your drawing and we'll confirm.
Can you match an existing plate?
Yes. Send dimensions or the original part and we'll reproduce it.
