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.
