For users of screwdrivers, today we will discuss six basic screwdrivers you need to know so as to
be effective and efficient on your job. Below are the sets of screwdrivers:
1. FLAT HEAD/SLOTTED SCREWDRIVER
The tool used to drive a slotted screw head is called a standard, common blade, flat-blade,
slot-head, straight, flat, flat-tip, or "flat-head" screwdriver. This last usage can be
confusing, because the term flat-head also describes a screw with a flat top, designed to
install in a countersunk hole.
2. CROSS SLOT/PHILLIPS SCREWDRIVER
A Cross slot screwdriver or Phillips screwdriver is a screwdriver with a cross tip and it is
useful for removing cross screws.
3. SECURITY TAMPERPROOF SCREWDRIVER
The Tamperproof spanner screwdriver is a complete security screwdriver set in one
driver. This 15-in-1 screwdriver is a must for all commercial and industrial tradesmen
including electricians, locksmiths, telephone technicians, maintenance personnel, etc.
4. HEXAGON SCREWDRIVER
The hex socket screwdriver has a hexagonal recess and may be driven by a hex wrench,
also known as an Allen wrench, Allen key, hex key, or inbus as well as by a hex
screwdriver (also known as a hex driver) or bit.
5. TORX SCREWDRIVER
Torx (pronounced /tɔːrks/), developed in 1967 by Camcar Textron, is the trademark for a
type of screw head characterized by a 6-point star-shaped pattern. A popular generic
name for the drive is star, as in star screwdriver or star bits.
6. POZIDRIV SCREWDRIVER
The Pozidriv (sometimes incorrectly spelled "Pozidrive") is an improved version of
the Phillips screw drive. ... While a Phillips screwdriver has slightly tapered
flanks, a pointed tip, and rounded corners, a Pozidriv screwdriver has parallel
flanks, a blunt tip, and additional smaller ribs at 45° to the main slots.
