Screwdriver bits are small, reliable, and removable metal tools designed to fit into screwdrivers and power drills to drive or remove screws efficiently. These hand tools engage with the screws or bolts’ head, allowing to turn it either clockwise or counterclockwise, depending on users’ needs. A screwdriver bit comes in various shapes, sizes, and lengths to match various screw heads and fasteners. Screwdriver bits are typically constructed from highly durable and solid materials, including steel, stainless steel, vanadium steel, and titanium, and often galvanised with diamond coating, black oxide, and titanium for enhanced corrosion resistance. In addition, screwdriver bits also come as a set of bits to fit multiple screw types in various applications.
Screwdriver Bit Sets
Screwdriver bit sets are collections of various types and sizes of screwdriver bits organised in storage cases or boxes for use with multiple compatible screwdrivers or power tools. These sets comprise different types of screwdriver bits, including Phillips, slotted, Torx, hex, square, and more. A screwdriver bit set is a go-to choice for DIY enthusiasts, contractors, and professionals, providing a convenient way to have multiple screwdriver bits at hand. Screwdriver bit sets ensure that the bits are organised and protected and facilitate their easy identification.
Popular Types of Screwdriver Bits
Screwdriver bits are categorised into various types based on their tip configurations, materials, and intended applications. Some of the most common screwdriver bit types include:
- Phillips Bits – Phillips bits have a cross-shaped tip to work with Phillips head screws, which have a corresponding cross-shaped indentation on the head. They are commonly used in many applications, including electronics and furniture assembly.
- Slotted Bits – Slotted bits feature a flat, single-line tip and are used with slotted or flat-head screws. These are less common in modern applications but can still be found in some older fixtures and hardware.
- Torx Bits – A Torx screwdriver bit has a six-pointed star-shaped tip and is used with Torx or star-head screws. They provide better torque and reduced risk of cam-out (slipping) compared to their counterparts, making them popular in the automotive and electronics industries.
- Hex Bits – Hex bits have a hexagonal (six-sided) tip and are used with hexagonal or Allen head screws and bolts. They are commonly found in furniture assembly and machinery.
- Square Screwdriver Bits: Square bits, also called Robertson bits, have a square-shaped tip and are used with square-drive screws. They provide good torque transfer and are prevalent in construction and woodworking.
- Pozidriv Bits – Pozidriv bits are similar to Phillips bits but have additional flutes in the head. They are designed to reduce the risk of cam-out and are often used in applications requiring high torque.
- Security Screwdriver Bits – Security bits have unique, tamper-resistant shapes to deter unauthorised access. These bits are commonly used for security screws found in electronic devices, gaming consoles, and public fixtures.
- Nut Driver Bits – Nut driver bits have a cylindrical shape that turn hexagonal nuts and bolts. They can be used with a screwdriver handle or a power drill.
- Phillips/Square Combo Bits – Also called Combo or Quadrex Bits, these bits have a combination of Phillips and square drive features, making them suitable for use with both types of screws.
- Alloy Steel-Tipped Screwdriver Bits – These are the standard steel screwdriver-bits ideal for lighter construction applications and DIY projects.
- Extra-Long Screwdriver-Bits – They are designed for working in hard-to-reach areas or cramped spaces. They reduce the torque force due to inconvenient spaces by avoiding camming out or twisting.
- General Purpose Screwdriver Bits – Ideal for typical daily applications (standard form).
