Units & conversion notes
- 1 inch = 25.4 mm. For inch-designated sizes, metric equivalents are rounded to a maximum of four decimal places; the inch designation identifies the nominal size.
- Converted diameters describe nominal size, not dimensional tolerance or precision grade.
- Weights are approximate kilograms per 10,000 pieces; quantities are approximate pieces per kilogram.

03 / USING THE CHART
How to Use This Chart
Match the diameter
Search in millimetres or use the listed inch fraction. Inch-designated sizes use converted metric values rounded to a maximum of four decimal places. Specify the nominal size and tolerance when ordering.
Estimate weight
Approximate weight (kg) = quantity ÷ 10,000 × the listed weight per 10,000 pieces.
Estimate quantity
Approximate quantity = weight (kg) × listed pieces per kg. Rounded reference values are not packing counts; confirm actual material, weighing and packaging.
Prepare your RFQ
Include material, diameter, grade, quantity and application. Each row’s quote link carries its diameter and, where supplied, its inch designation to the enquiry form.
