Packingcoil/small coil wire
Define the measured wire diameter and loop configuration before ordering a small coil binding supply.
Range and gauge
The menu is a 0.7–4 mm range, matching the described gauge span. BWG16 remains a title requirement needing a named conversion and a confirmed individual diameter.
Annealing and surface
Black surface and annealing are recorded alongside a bright finish field. Agree the actual appearance and delivery condition rather than assume those words define the same surface specification.
- Measured wire diameter
- BWG conversion if needed
- Loop and end dimensions
- Coil handling arrangement
- Surface and mechanical criteria
Inspection basis
The source states 350–550 MPa tensile strength and ±0.03 mm tolerance. Confirm applicability to the selected size and condition, and request the actual material designation instead of deriving a steel grade from isolated chemical figures.
