M3–M10 Rivnut Graduated Sort Tray
A 152 x 76 x 22 mm tray with six cells for rivet nuts (rivnuts). The cells get wider with thread size: 16, 18, 20, 24, 28 and 32 mm, for M3, M4, M5, M6, M8 and M10. A front gauge ledge has a through-hole in front of each cell (3.4, 4.5, 5.5, 6.6, 9.0 and 11.0 mm, the ISO medium clearance sizes). Drop your install mandrel or bolt into a hole to check which cell it matches, so you never have to dump out a mixed bag and guess the thread size by eye again.
Pop Rivet Stand-Up Sort Rack
A 130 x 66 x 34 mm rack that holds 24 blind pop rivets upright by the head, so the mandrel hangs into a hollow channel below. It has one row of eight holes for each common rivet size: 1/8 in (3.2 mm) in 3.4 mm holes, 5/32 in (4.0 mm) in 4.5 mm holes and 3/16 in (4.8 mm) in 5.5 mm holes. Sort grip lengths left to right along each row. The 1, 2 and 3 dimple dots mark the rows, and each hole also works as a quick check that a rivet fits.
