A 500-piece assortment of M3 and M4 metal screws, R-pins, and shell fasteners — all organised in a sectioned plastic case with three small spanners included. No more hunting for that one missing screw mid-build.

• 500 pieces – M3 and M4 screws, R-pins, and assorted fasteners
• Material: Metal fasteners in a plastic compartmentalised storage box
• Includes three small spanners for quick tightening
• Weight: Approx. 350 g – compact enough for the workbench or a tool bag

Who it's for: Ideal for homelab builders who regularly mount 2.5" and 3.5" drives, secure Raspberry Pi cases, attach cooling fans, or assemble rack shelves. M3 and M4 are the most common thread sizes you'll encounter in server and SBC builds, so having a well-stocked box on the bench saves real time. Also handy for general electronics projects and small RC or maker work.
