Why Lock

Why the screw stays in our own tool room

  • Dies and rolls made in house

    Heading dies and thread rolls are cut in our own tool room, so a special head or drive adds days to the sample rather than weeks to the project.

  • Gauged on the finished screw

    Thread size, head concentricity and drive depth are checked on the part you receive, not inferred from the blank.

  • Your drawing stays yours

    NDA on request. Files are never shared with third parties or reused for another customer.

FAQ

Common questions

What counts as a non-standard screw?

Anything the catalogue does not cover: a head geometry, drive recess, thread pitch, point or coating that is not a stock item. A 2D drawing or a sample screw is enough to quote — we measure it and work from that.

Do you charge for heading tooling?

Yes, and it is quoted openly as a separate line rather than folded into the unit price. The die stays with your part number, so a repeat order does not pay for it again.

What range of sizes do you cover?

M0.6 at the small end, up to M24 for long screws and studs. Lengths follow the drawing; anything outside that range is quoted case by case.

Is my drawing confidential?

Your drawing is used only to quote and make your parts. An NDA can be signed before you upload, and files stay on our own server and are deleted after 180 days.

What is your minimum order?

One piece for machined parts. Stamping and cold-formed fasteners start from the tooling, which is quoted as its own line.

How do you ship, and who handles customs?

EXW, FOB, CIF, DDU or DDP — we can deliver to your warehouse and handle the clearance.
