M2 To M5 Fastener Sort Tray
A 140 x 85 x 16 mm bench tray with six sloped-floor bins — four 32 x 30 mm pockets for M2/M2.5/M3/M4 screws, nuts and washers, plus two full-length 32 x 62 mm bins for nylon standoffs and longer screws. The front ledge is a screw gauge: four through-holes (2.4 / 3.4 / 4.5 / 5.5 mm) let you drop an unknown fastener through and read off M2, M3, M4 or M5, and every bin floor rises 4 mm toward the back so parts collect at the near edge instead of hiding in a corner.
