Hex Bit for use with M3 (3 mm bolts). M3 bolts have a shaft thread diameter of 3 mm, but the hex socket in the head is 2 mm in diameter. These hex bits are sold individually and made from hardened S2 grade steel. This is a stronger grade of steel than what you will usually find in cheap screwdriver sets, which have interchangeable heads. Most of the bits made from softer steel will be shiny / polished in appearance. Swapping them out for this bit will lessen the chance of stripping hex bolts when trying to undo them.
The end that is inserted into the screwdriver is a standard 4 mm size.
