A fastener is primarily made by Cold Forging / Heading. Cold forging (cold heading) forms metal at room temperature by forcing it into a die, work-hardening the part and giving an excellent finish with almost no waste. Below is the full route to make a fastener, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a fastener is made
The usual route, raw material to finished part. The amber step is where the fastener gets its basic shape.
Material
Cut billet or bar stock to size for the fastener.
Cold Forging / Heading
Force the metal to shape at room temperature: the grain follows the form and gives the fastener its strength.
Tooling High Tolerance ±0.05 to 0.25mm Lead 8 to 16 weeks
Trimming
Trim the flash and pierce any webs the dies leave behind.
Heat treatment
Normalise, quench and temper to the final mechanical properties.
Tooling n/a Tolerance can distort Lead days
Machining
Machine the bearing surfaces, threads and precise features to tolerance.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Inspection
Dimensional check plus crack detection on safety-critical parts.

Cost
What a fastener should cost
Fasteners and near-net parts at huge volume; pennies per part once tooled. A high-volume game.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a fastener at your volume, in your currency, are in the dossier.

A fastener is primarily made by cold forging / heading. The route is: Material; Cold Forging / Heading; Trimming; Heat treatment; Machining; Inspection.
What does a fastener cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $0.15 to 0.32 per part at 1,000 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is a fastener made from?
Common choices are Low-carbon wire (CHQ); Alloy steel wire; Stainless/alu wire.
What is the main process for a fastener?
Cold Forging / Heading. High-volume small parts like fasteners, pins and studs where strength and material yield matter.
