Tri-wing screwdrivers are common in the aerospace industry to use with screws and bolts holding together commercial aircraft. The three slotted wings surround a small triangular hole in the center. The slots are offset and do not meet at the center of the screw or bolt.
Tri-Wing Screws are the common choice for high volume assembly operations while offering a minimal degree of security. Machine screws & sheet metal screws are offered in a Pan-Head design and Opsit® reverse thread.
Tri-wing screwdrivers are another common form of security driver bit. These screwdrivers look similar to Phillips drivers but have three blades instead of four. Also, the blades (the wings) are slightly offset and do not meet in the middle. These screwdrivers are common in the aerospace field.
Phillips screwdriver bits and sets
Phillips screwdriver bits are among the most widely used of all types today.
The unique Tri-Lobe handle shape gives you a firm but comfortable grip, improving your leverage and helping you apply more force. Each of the six screwdrivers features a hardened magnetic tip that's built to last, plus a three-sided anti-roll collar to ensure it won't move if you put one down.
Tri Wing. Tri-wing screwdrivers are only compatible with a fastener head that has three slotted "wings" and a small triangular hole in the center. Also known as triangular slotted, the slots are offset and do not intersect in the center of the fastener.
Triangular head security bolts, also called triangular head security screws or security recess screws, are manufactured to DIN 22424 and consist of flange headed bolts with deep triangular heads.
Wrapping Up the Various Screw Bit Types
While some types of screwdriver bits are less common, at the very least, be sure to keep a handy assortment of both straight, Philips, Torx, and square head screwdrivers and bits on hand.
Pozidriv (PZ) Type Screwdrivers
A pozidriv (PZ) type screwdriver is used for tightening or loosening pozidriv type screws. PZ screws are very similar to phillips type screws but they include 4 more contact points for increased control and precision.

Those odd screws are known as “tamper-resistant” screws and take several forms, from obscure bit types a vandal is not likely to have on them, or purpose-made types such as snake-eye screws. I imagine your toaster has an electrical compartment that the manufacturer does not want a user to tamper with.
Torx screws are typically used in vehicles, motorcycles, bicycles, computer systems, hard disk drives and consumer electronics. The unusual star-shaped head makes them far more secure than regular flat-head or cross-head screws and allows higher torque transmission so screws and bolts can be tightened more securely.
Popular hex head screw applications include: Machinery: Hex head screws are a common choice for fastening and disassembly in machinery projects and equipment assembly. Construction: Hex screws are used in masonry and construction projects, especially those using steel and wood.
Electricians tend to use insulated VDE screwdrivers and help prevent the electrician from receiving a shock or, worse, being electrocuted.
Called Torx, 6 point, and star, Torx are a 6 pointed star shaped screwdriver. Originally designed in the 60's to outperform hex screws, Torx is a trademarked name for a screwdriver that fits Torx screws, commonly seen in sizes Torx 6 to Torx 40 (or T6 to T40).
Hex bolts, also called hexagon screw head bolts, hex cap bolts, hex-cap screws, or machine bolts, are a very common choice when it comes to construction and repair. Hexagon screw head bolts come in a large variety of sizes and diameters.
Tri-wing screwdrivers are common in the aerospace industry to use with screws and bolts holding together commercial aircraft. The three slotted wings surround a small triangular hole in the center. The slots are offset and do not meet at the center of the screw or bolt.
The name cheese head is derived from the similarity in shape and proportion to that of a wheel of cheese. Fillister head slotted screws, also known as raised cheese head slotted screws, are similar to cheese head slotted screws because both have cylindrical sides and a flat mating surface.
What are the most common impact driver bits? An impact driver bit set should include the following bit types: Phillips, flat, torx, square, nut driver, and a socket adapter. These bits should be sufficient to tackle nearly all tasks. Some sets also include hex and drill bits for added versatility.
A Robertson screw, also known as a square screw or Scrulox, is a type of screw with a square-shaped socket in the screw head and a corresponding square protrusion on the tool. Both the tool and socket have a slight taper.
The strongest screw heads are typically star-shaped, Torx bits, or square-shaped, Roberts bits. However, a well-fitted Philips head is also strong.
The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside. The screw passes through a hole in another object or medium, with threads on the inside of the hole that mesh with the screw's threads.
