Fastener Weight Calculator

Quick answer

Fastener weight estimates scale with diameter, length, material, and quantity using density assumptions.

Actual heads, threads, and coatings shift mass slightly versus idealized cylinders.

Use the estimator below for kits and shipping, then weigh samples when billing depends on mass.

Estimate the weight of a quantity of bolts or screws.

Size inputs against M10 bolt size tables when you pick diameters from stock lists.

Use thread types when thread mass and pitch series affect the estimate.
