At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM A108. ASTM A108 covers cold-finished carbon and alloy steel bars (rounds, squares, hexagons, and flats) produced by cold drawing, turning, grinding, and polishing. It is a raw-material bar standard from which fasteners, shafts, pins, and machined components are made; mechanical properties depend on the specific grade and cold-work condition rather than a single value. Common grades include 1018, 1045, 1215, and 12L14.

| Grade / Class | UNS / Designation | Type / Notes |
|---|---|---|
| 1018 | G10180 | Low-carbon, general purpose, good weldability/machinability |
| 1045 | G10450 | Medium-carbon, higher strength, induction/flame hardenable |
| 1215 | G12150 | Resulfurized free-machining carbon steel |
| 12L14 | G12144 | Leaded free-machining carbon steel (highest machinability) |
| 1144 | G11440 | Resulfurized medium-carbon, stress-proof type |

General bar requirements per ASTM A29; grade chemistries follow SAE J403/AISI designations. Free-machining grades parallel EN 10277 (11SMn30 ~ 1215, 11SMnPb30 ~ 12L14).
