The Right Nut for Every Bolt
Screws get used up in projects, but it is usually the nut that goes missing. This assortment keeps every common metric size from M2 to M6 in the drawer, in three nut styles plus washers.
Standard Hex Nuts
Standard hex nuts for everyday fixings, through bolts and printed nut traps.
Thin Hex Nuts
Thin hex nuts fit tight spaces and shallow nut traps, and can be run against another nut to lock it in place.
Nyloc Nuts and Washers
Nyloc nuts have a nylon insert that resists loosening from vibration, and washers spread the load on printed plastic.
