Some consumer appliances, such as espresso machines from Jura Elektroapparate, use a proprietary screw head with an eccentric oval to dissuade owners from servicing their own machines.A Phillips screw head is slightly different from a PoziDriv; [10] see §Pozidriv section below for details. When the screw is stripped, the job will become much more difficult. Using the wrong screwdriver for the job at hand could also destroy your screwdriver.

However, Torx and other drivers have become widely available to the consumer due to their increasing use in the industry. Some other styles fit a three-pointed star recess, and a five-lobed spline with rounded edges instead of the square edges of the Torx. This is called a Pentalobe.

A thumbscrew is a type of screw drive with either a tall head and ridged or knurled sides, or a key-like flat-sided vertical head. They are intended to be tightened and loosened by hand, and are usually not found in structural applications. They are sometimes also cut for Phillips head or slotted screwdrivers, as well as having the knurling for finger grip. ASME Standard 18.6.8 covers dimensions for Type A (shoulder under the head), regular and heavy, along with Type B (without shoulder), regular and heavy. They can be found on many computer cases, and in other locations where easy access without tools is desired. The Phillips Screw Company owns the licensed product that is the Mortorq spiral drive system. The Phillips Screw Company must inspect and approve any punches, bits, and screws before they are cleared for production. Along with this "all licensees must submit samples regularly to ensure that the strict quality standards are maintained". [38] Solid modeling is used for the design of the punches, bits, and screws. Files are sent over to manufacturers containing these models so that there is no miscommunication and all the parts are the same across the board. a b Radio Material School, Naval Research Laboratory.

Other combinations are a Phillips and Robertson, a Robertson and a slotted, a Torx and a slotted and a triple-drive screw that can take a slotted, Phillips or a Robertson. The handle and shaft of screwdrivers have changed considerably over time. The design is influenced by both purpose and manufacturing requirements. The "Perfect Pattern Handle" [ further explanation needed] screwdriver was first manufactured by HD Smith & Company, which operated from 1850 to 1900. Many manufacturers adopted this handle design. At the time, the "flat bladed" screw type was prevalent and was the fastener with which they were designed to be used. Another popular design was composed of drop-forged steel with riveted wood handles. There are multiple sizes of Phillips head screwdrivers, with tip measurements sometimes varying by just half a millimeter. With such a small size difference, can’t you get away with using the wrong driver on the wrong screw?The Phillips head screwdriver was created and patented by Henry Phillips in the 1930s and was originally used on the 1936 Cadillac. The great thing about it is that unlike the flat head screw (with a single ridge at its tip to slide into a screw with one slot), the Phillips screwdriver is self-centering. Its “X” design won’t slip out of the X-slotted screw. Instead, it grips the screw firmly in the center, provided it’s the suitable size for the screw. There are many other Phillips head screwdriver sizes that are less common and used for more specialized tasks. You will use these only if you working on very specific projects, such as eyeglasses repair or precision electronics assembly.
