Types of screwdriver bit sets

Screwdriver bits come in various types like regular screwdrivers. Below you will find the most common types listed. Bit sets can come with variations in both size and shape or all the same size and shape. We have outlined the most common types of bits below.

• Flathead bit - Also referred to as a slot screwdriver bit. Their main feature is a flattened tip used for screws with a straight linear recess.

• Phillips' bit - Also known as crosshead bits, Phillips' bits are one of the most common types next to the flathead and are purposely designed to fit screws a cross-shaped recess.

• Torx/Star bits - Commonly known as star head bits, these screwdriver bits are designed to fit six-pointed screw recesses (also known as Torx screws).

• Tri-Wing bits - These are used for specific devices and mainly feature quite small tips to enable use with smaller screws and components.

• Pozidriv bits - These are designed as an upgrade to Phillips' bits and help to reduce "camming out", in which the bit jumps out of the slot.

• Hex bits - These bits function much like hex keys and are designed to fit hexagonal screw slots

• Square bits - Much like the hex bits, these types of screwdriver bits fit with square recesses and deliver good purchase especially when tightening.

• Magnetic bits - Some screwdriver bits feature magnetic tips. These come in handy when working in confined spaces where losing a fastener in hard to reach places is a risk.
