To remove and tighten nuts with hexagonal (six-sided) heads, use a hex driver, as shown in Figure 2-10. Hex bolts should not be overtightened since the threads might be stripped. Use a hex driver that is the correct size for the bolt you're working with. Some types of bolts require special drivers, such as an impact driver or sledgehammer to get them off.

The best way to ensure the safety of yourself and your family is by following common sense practices when working on vehicles. Always wear protective clothing (including gloves) when handling tools and materials. Keep all equipment and materials away from children. Never work on vehicles during rainy conditions or in high wind speeds. If you feel uncomfortable about working on a vehicle, then ask for help from someone who knows more about cars than you do.
2. Use a hex driver to loosen and tighten bolts with hexagonal (six-sided) heads. Do not use a hex driver that is too large for the bolt you are working with. This could cause you to waste time removing your driver before each use.
Hex bolts, also known as hex cap screws, are huge bolts with a six-sided (hexagonal!) head that are used to secure wood to wood or metal to wood. There are numerous various types of heads on wood screws, but the most popular are round heads and flat heads. The head of a round-headed wood screw is fully above the workpiece. That means that if you were to look down at your bench top while using a round-headed wood screw, you would see its head. Flat-head wood screws have flat surfaces where the head would be if they were looking up at you. They can be harder to find than round-headed screws, but they're common enough.
Hex bolts are usually made of stainless steel or titanium, but aluminum ones are also available. Their length varies from manufacturer to manufacturer, but most are between 5/8 and 1 inch long. The diameter of a hex bolt depends on how much force you want to apply to it. If it's going to hold only light items such as picture hooks or earbuds, then a smaller diameter bolt is sufficient. If it's going to hold large items such as shelves or cabinets, then use a larger diameter bolt.
Hex bolts are easy to use for beginners because there's no special tool required to drive them. All you need is a standard wood screwdriver. You can also use a hand-powered drill for drilling small holes if you don't have a power tool available.
They're often used as door and window frame locks because they can be driven straight into the frame without drilling.
The name "hex bolt" comes from the fact that they look like miniature hex nuts. Hex bolts are usually made of stainless steel but aluminum bolts are available too. Their diameter varies between 3/8" and 1-1/4", depending on the application. The length ranges from 9"-40".
Because they can be tightened by hand, these bolts are suitable for use as anchor bolts or lockbolts. They can also be used in place of standard bolts if you want to avoid having to drill holes in your wood frame.

Hex bolts are used everywhere wood is used. That includes both inside and outside your home. You find them used as drawer pulls, window shutters, and balcony railing supports. Of course, they are also used in vehicles as body panel fasteners and floor pan fasteners.
