Weight & logistics
Unit weight is calculated, not guessed.
Calculated from final geometry and selected alloy density; confirmed on the quotation. Piece count, net weight and gross shipment weight confirmed before dispatch.
- 01Final geometry
Diameter, length, head or body profile and thread allowance.
- 02Alloy density
The selected material grade is applied to the finished net volume.
- 03Quotation schedule
Net piece weight, order weight and estimated packed weight are listed.
