Typically, a stud bolt refers to an un-headed fastener, like a piece of all thread rod. A hex bolt is common a six-sided fastener, available in many grades.
Having 6 points of contact rather than just 4 (for square bolts and nuts) reduces the tendency to damage the nuts by shearing the edges. Of course, square bolts have an advantage if using an alternative tool (pliers, lock-grips) to hold or turn the bolt, because there is a wider surface to grip than with hex bolts.
There are more than two types, but the main categories are flat head and cross/star screwdrivers. Actually, there are four: flathead or standard, phillips head, hex or Allen head, or Torx or star head. Torx/star head and Allen/hex head fasters are more often than not bolts, differentiated from screws, but there are a number of different styles of actual screws that are manufactured for these two bits as well.
The 74xx series of integrated circuits use TTL technology. (Transistor Transistor Logic). They work on 5v power supply, and draw a larger current. The MC type chips are CMOS. (Complementary Metal Oxide Silicon) they work off a more varied voltage range, 5v - 18v and draw less current than TTL. Other different numbers will relate to the package design and speed of operation.
Bob Mimlich invented hex bugs.
Hex, or Allen screwdrivers are for screwing and unscrewing Allen head screws.
The different types of stem bolts used in a bike are typically hex bolts, socket head bolts, and cap bolts. These bolts are used to secure the stem to the handlebars and the fork of the bike.
The torque specs for 660 raptor head and hex bolts is about 26 lbs.
they are Allen bolts
Hex bolts or carriage bolts are commonly used to secure table legs effectively. These types of bolts provide a strong and stable connection between the table legs and the tabletop.
Hex bolts are typically recommended for securing handlebars on a bike.
Typically, bed frames require hex bolts or screws for assembly.
There are several types of lag bolts available in the market, including hex lag bolts, square lag bolts, and round lag bolts. These bolts differ in their head shape and the type of wrench needed for installation. Hex lag bolts have a hexagonal head and require a wrench or socket for tightening. Square lag bolts have a square head and are typically installed with a wrench. Round lag bolts have a rounded head and are usually tightened with a wrench or pliers. Each type of lag bolt is designed for specific applications and offers varying levels of strength and durability.
Heavy hex head has a larger bearing surface. For example a 1" heavy bolt 1-5/8" dimension across the flats. A finish hex bolt is 1-1/2". This creates a strong fastener. This is one reason many high strength structural bolts like ASTM A325 and A490 are specified a heavy hex pattern. The head thickness is identical for both bolts. These bolts are often found in industrial and steel connection situations. The stronger design is critical.

THE HEX BOLT SIZE IS 3/8 AND YOU CAN GET ONE AT ANY AUTO PARTS STORE FOR AROUND $5.00
The multi hex tool is a versatile tool that features multiple hexagonal-shaped ends of different sizes. It is used for tightening or loosening bolts and screws with hexagonal heads. The tool's functions include providing a secure grip on fasteners and allowing for precise torque application. Its compact design makes it convenient for various tasks that require hex keys of different sizes.
A hex driver is a tool designed to drive screws and bolts that have hexagonal (six-sided) recesses in their heads. It typically features a hex-shaped tip that fits into these recesses, allowing for efficient tightening or loosening. Hex drivers come in various sizes and can be manual (like a wrench) or powered (like a drill attachment), making them versatile for different applications in construction, automotive work, and DIY projects.
