These are high-quality M2 set screws made from hardened steel that are 3mm long. This is the most common length for M2 set screws used on 1/32 slot cars - they are used by many manufacturers to secure wheels and gears. For example, Slot.it (tm) uses M2 x 3mm set screws for wheels, crown gears and spur gears. They can also be used in lieu of eyelets to secure car braid into the guide.
Note: Requires .9mm (.035") hex driver which is available for purchase separately.
Package contains ten (10) set screws.
