Bolts Weight Chart & Calculator – Bolt Weight in Kg, mm & Inch

The Bolts Weight Chart is a critical engineering reference used for accurate material estimation, project costing, logistics planning, and bulk procurement across construction, fabrication, oil & gas, and manufacturing industries. Bolt weight directly impacts structural load calculations, transport costs, and inventory planning, making precise weight data essential for engineers and purchasing teams.

This comprehensive bolt weight chart provides bolt weights in kilograms, millimeters, and inches, helping users quickly calculate total fastener weight based on bolt diameter and length. The chart covers commonly used imperial bolt sizes ranging from ½″ to 1½″ diameter, making it suitable for structural and heavy-duty applications.

For dynamic calculations, users can also refer to a bolts weight calculator, allowing accurate conversion of piece weight into total shipment or project quantities. Together, the chart and calculator serve as a reliable reference for engineering and procurement professionals.
