Raw material through to final inspection, laid out so a part never has to leave the group to get finished.

Raw material storage

Raw material storage

Certified wire rod coils in 1010, 1018, 15B25, 16MnCr5 and SS316, checked on incoming inspection before they reach the floor.

Cold forging

Cold forging

Multi station nut formers and part formers develop complex items through the cold forging route.

Tool room and EDM
Tool room and EDM, second view

Tool room and EDM

The in-house tool room turns tooling for routine and new development items around quickly: lathe machines, tool and cutter grinding, and EDM.

CNC section

CNC section

CNC turning centres hold close tolerances on critical items, backed by VMC and band saw machines.

Secondary operations

Secondary operations

Tapping and threading set-up, shot blasting, friction press and metal fibre laser marking.

Surface treatment

Surface treatment

Zinc flake coating, blackening, zinc plating and pre-applied treatments, none of it leaving the group.

In house lab facility

Calibrated, and used every day

The lab exists so defects get caught here rather than on your line. Every instrument is calibrated and the result goes on the batch record, which is why the report that ships with a batch is ours and not a third party’s.

Salt spray chamber

Salt spray chamber

Presto

Corrosion testing to ASTM B117. Coated parts run to red rust so the hours on the report are ours, not a supplier's.

Coating thickness

Coating thickness

Fischer

Fischer machine, DFT meter and XRF, for plated and zinc flake layers on threads and flats alike.

Profile projector

Profile projector

Optical form, thread profile and radius checks against the drawing, with air gauging alongside.

Hardness and SRF

Hardness and SRF

Rockwell

Rockwell hardness tester and SRF machine, run on every heat treated and formed batch.

Torque testing

Torque testing

Syscon

Torque and tension on assembled fasteners, which is what a pre-applied or coated thread is finally judged on.

Gauges

Gauges

Baker

Ring gauge, pluge gauge, Baker make, vernier and micrometre, with the graticule reader, for dimensional work.

Reports issued with the batch, not on request.

Audit us before you buy

Vendor onboarding usually means a plant visit and a document pack. Both are easy to arrange, and we would rather you came than took our word for it.
