Cold-forging machines, thread-rolling machines, and complete fastener production lines are the foundational capital equipment for the global fastener industry. A single fastener factory typically produces 50-500 million fasteners per year. China dominates global fastener manufacturing and is also the leading source of fastener-making machinery, supplying both Chinese fastener factories and increasingly exporting to Vietnam, India, Mexico, Turkey, and other manufacturing regions. For fastener factory investors, industrial machinery distributors, and existing fastener manufacturers planning expansion, sourcing fastener-making machinery from a Chinese specialist manufacturer delivers significant cost savings vs Japanese (Sakamura, Nakashimada) and European (Hatebur, Bühler) Tier-1 brands.
This guide covers the Anchors Machinery product family — multi-station cold-heading machines (for bolts, screws, rivets, complex fasteners), thread-rolling machines (hydraulic and mechanical, two-axle and three-axle), wire drawing and straightening equipment, fastener finishing equipment, and complete fastener production lines.

Multi-station cold-heading explained
| Stations | What it produces |
|---|---|
| 1-die 2-blow (1D2B) | Hex head bolts, round head screws — standard simple fasteners |
| 2-die 2-blow (2D2B) | Hex bolts with point chamfering — secondary features |
| 3-die 3-blow (3D3B) | Socket head cap screws, flange bolts — complex heads |
| 4-die 4-blow (4D4B) | Complex specialty/automotive fasteners — precision geometry |
| 5-die 5-blow (5D5B) | Precision automotive/aerospace fasteners — tight tolerances |
| 6-die 6-blow (6D6B) | Premium specialty fasteners — highest complexity |
Cold-heading economics vs hot forging vs CNC machining
COLD-HEADING — wire stock deformed at room temperature; 150-450 pieces/min, >95% material utilization, excellent dimensional accuracy. Best for high-volume bolts, screws, rivets. HOT FORGING — material heated then formed; works for harder materials and larger sizes; lower productivity. Best for large fasteners (M24+), high-tensile, specialty geometries. CNC MACHINING — turned/milled from bar stock; extreme flexibility but very low productivity (10-50 pieces/min), poor material utilization. Best for low-volume specialty/prototype. ECONOMICS: cold-headed bolt USD 0.02-0.05 each vs hot-forged USD 0.08-0.18 vs CNC USD 0.50-3.00. Production line investment higher for cold-heading but per-piece cost dramatically lower at high volume.
