Taken from LAS Aerospace's product page on 2026-09-30. Where the listing does not state a figure, this table does not either.
What it is for
LAS's case for tungsten: a bar light enough to fit can be too light to drive the rivet without work-hardening it. The listing gives dimensions but not weights.
Steel alternatives with weights: cast steel bucking bars.
