*by C***O on 30 December 2024*

Arrived quickly, as described. A very handy boxed kit of black nylon washers of varying sizes, diameter and thickness (see photo, or list below). There are tags (see photo) on most of the washers which would need cut off if it's a neat fit you're after. Overall though, these are good washers for the money. Do note that 300 of the 500 are tiny (M2 & M2.5 & M3). The size description list below states: 1. Thread size to fit hole e.g. M2 2. The washer outer diameter in mm e.g. 5mm 3. The washer thickness in mm e.g. 1mm M2x5x1 100pc M2.5x5x1 100pc M3x6x1. 100pc M4x8x1 50pc M5x10x1 50pc M6x12x1.2 x50pc M8x16x1.4 x40pc M10x20x2 x10pc
