Why Lock
Flange bolts and serrated head screws are cold-formed in house, so prevailing torque survives road vibration instead of relying on a thread-locking patch.
Zinc, black zinc, hot-dip galvanising and passivated A4-70, with salt-spray hours quoted per finish and tested on request.
Dimensions, thread gauges and hardness are recorded lot by lot, and the report travels in the box with the parts.
The same press runs a 500-piece service batch and a 100K production order, with no tooling charge either way.
Stamped brackets, clips and reinforcement plates come off our presses, so a joint can ship as one kit on one packing list.
When a model is discontinued, we keep the tooling, so a service order years later does not need a new drawing or a new die.
Vehicles punish fasteners: vibration, salt spray, torque cycling and a build date that does not move. We make flange bolts, head screws and A4-70 stainless fasteners for exactly that, in grades 8.8 to 12.9, with zinc, black zinc, galvanised or passivated finishes.
Most of the automotive work we ship is cold-formed in house and inspected lot by lot — dimensions, thread gauges and hardness — with the report travelling in the box.

Send a sample or a drawing with the property class and finish. We measure it and quote the same part, or the nearest standard we can hold, and say which one it is.
Zinc, black zinc, hot-dip galvanising and passivated stainless A4-70. Salt-spray hours are quoted per finish, and a lot can be tested to 240 hours on request.
Yes. Brackets, clips and reinforcement plates are stamped in the same workshop, so a fastener order can leave as a complete kit.
Send it over — we will tell you what it costs and whether it is the right process.
