Screwdriver Bits

screwdriver bits are tools for driving screws and can be fitted to most drilling power tools. They come in different sizes and types, such as Phillips, Slotted, Torx, Hex, and Pozidriv. They are made from durable materials, such as steel or carbon steel, and some are designed for impact mode.

There are many types of screwdriver bits, each with different shapes and sizes to fit different types of screws. Some of the most common types of screwdriver bits are:

 
• Slotted: These have a single flat blade that fits into a straight slot on the screw head. They are simple and inexpensive but can slip easily and damage the screw or the surface.
• Phillips: These have a pointed cross-head tip that matches a self-centering, cross-head screw. They were designed to prevent over-tightening, but can also come out and strip the screw head.
• Pozidriv: These are similar to Phillips, but have four additional ribs between the main cross blades. They provide more grip and torque than Phillips but require a matching screw head and bit size.
• Torx: These have a six-pointed star shape that fits into a corresponding recess on the screw head. They offer high torque and resistance to cam out but are less common and more expensive than other types.
• Square: These have a square tip that fits into a square hole on the screw head. They are also known as Robertson bits and are popular in Canada and the US. They provide good torque and stability but can be difficult to remove if over-tightened.
• Hex: These have a hexagonal tip that fits into a hexagonal socket on the screw head. They are also known as Allen bits and are widely used for furniture assembly and bicycle repair. They offer high torque and a low risk of slipping but can strip the socket if too much force is applied.
• Hexlobe: These have a six-pointed star shape with a circular indentation in the center. They are also known as Torx Plus bits and are an improved version of Torx bits. They offer more contact area and less wear than Torx bits but require special screws and bits.

There are also other types of screwdriver bits, such as security or tamper-proof bits, which have special features to prevent unauthorized removal of screws. Some examples are Torx Security, which has a pin in the center of the star shape; Tri-Wing, which has three curved wings; and Spanner, which has two notches on opposite sides of the tip. These types of screwdriver bits are usually used for electronic devices, appliances, or vehicles.

 
• PH tips: We can discover PH hints in a variety of aspects of our everyday lives, but we may emphasize their application in the building or electrical appliance industries, for example. Among the several PH impact tips are PH1, PH2, and PH3.
• PZ tips: PZ tips are quite common in the realm of wood furniture making. That is why PZ bits are appropriate for such operations since many furniture construction jobs use PZ head screws. Among the several PZ impact bits are the PZ1, PZ2, and PZ3.
• TX tips: TX tips are often used in the automobile, motorcycle, and electrical appliance industries. As a result, TX bits are appropriate for use in impact screwdrivers for these industries. The T10, T15, T20, T25, T30, and T40 are among the several TX impact bits.

• Slotted: The size of a slotted bit is measured by the width of the tip in millimeters or inches. Common slotted sizes are 3.5mm, 5.5mm, and 6.5mm in metric, and 3/32, 3/16, 1/8, and 1/4 in inches.
• Phillips: The size of a Phillips bit is indicated by a number code from #0 to #5, with #0 being the smallest and #5 being the largest. Common Phillips sizes are #0, #1, #2, and #3.
• Pozidriv: The size of a Pozidriv bit is also indicated by a number code from #0 to #5, similar to Phillips. However, Pozidriv bits have a different shape and require a matching screw head and bit size.
• Torx: The size of a Torx bit is indicated by a letter code from T1 to T100, with T1 being the smallest and T100 being the largest. Common Torx sizes are T10, T15, T20, T25, and T30.
• Square: The size of a square bit is indicated by a number code from #0 to #4, with #0 being the smallest and #4 being the largest. Common square sizes are #1, #2, and #3.
• Hex: The size of a hex bit is measured by the width of the tip across the flats in millimeters or inches. Common hex sizes are 3/32″, 1/8″, 5/32″, and 3/16″ in SAE, and 2mm, 2.5mm, 3mm, and 4mm in metric.
• Hexlobe: The size of a hexlobe bit is indicated by a letter code from IP1 to IP100, with IP1 being the smallest and IP100 being the largest. Hexlobe bits are similar to Torx bits but have a circular indentation in the center.
