Inside the plant
How your fasteners are made
Every part we ship moves through the same six stages, in our own plant. The controls listed under each stage are the ones that decide whether a fastener meets its class — not marketing copy.
-
01 Cold heading
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
-
02 Thread rolling
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
-
03 Heat treatment
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
-
04 Surface treatment
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
-
05 Sorting & inspection
Optical sorting checks every piece for dimension, thread condition and mixed parts, so a carton of M8 contains M8 and nothing else.
Automated 100% sort on critical dimensions, plus AQL sampling.
-
06 Packing & dispatch
Bulk, boxed or bagged to your part numbering, with the material test report and the lot number travelling in the carton rather than arriving by email a week later.
Lot traceability from carton back to the furnace charge.
