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

The listing pairs each pilot with its fastener, and the rivet pairs agree with our drill chart: #40 for 3/32", #21 for 5/32".

They go in a microstop; for confined spots, the extended microstop takes 3/8" cutters instead.
