Fgruh M6 Screw Assortment Kit 172pcs Hex Socket Head 304 Stainless Steel

172-piece M6 assortment kit

This 172-piece kit supplies 48 M6 socket-head bolts in eight lengths from 8 mm to 35 mm, plus 24 hex nuts, 50 flat washers, 50 spring washers and a mini wrench. The 304 stainless steel resists corrosion and meets standard metric tolerances with an average error below 0.01 mm. It is aimed at hobbyists and technicians who need a ready selection of M6 fasteners for 3D printers, RC models, bicycles and general DIY repairs. Builders requiring diameters other than M6 will need a separate kit.

Compartmentalised case for bench organisation

The divided storage box labels each length and component so the correct bolt, nut or washer is visible at a glance. Having nuts and both washer types in the same tray removes the need to source matching hardware separately. The included mini wrench handles the 5 mm hex drive on every bolt without hunting for a tool. Projects that demand longer M6 bolts or a different thread pitch are outside this kit's scope.

Eight standard lengths cover common clearance needs

Bolt lengths of 8, 10, 12, 16, 20, 25, 30 and 35 mm at a 1.0 mm pitch handle typical sheet-metal, bracket and frame thicknesses. The 304 stainless material provides high hardness and rust resistance for indoor and outdoor use. The assortment stops at 35 mm, so deeper joints or thicker stacks will require longer fasteners not included here.
