CO RODE 171-Pieces Stainless Steel Nylon Lock Nut Assortment Kit - M3 M4 M5 M6 M8 M10 M12

very good

This lock nut assortment works wonders for motorized my bicycle projects. I tinker with & build motorized bikes as a hobby. Currently putting together a 2 stroke beach cruiser & this lock nut assortment comes with just about every nut size used on the bike. Even used 4 of the M8 lock nuts on the engine mounting studs to secure the motor clamps to the bike better. Also love that it comes with M5 lock nuts to. The M5 lock nuts really helps secure my rear rack to the bike. Also find myself using M6 on allot of things so having plenty of M6 lock nuts comes in handy. Better than dealing with locktite on the bolts.
