2 Anchor Bolt An anchor bolt is usually used too attach objects or structures too concrete. All of these types of bolts include a nut and a washer, which is used too be attached to external loads. The anchor bolt is often used for making standard buildings, to dams, and also nuclear power plants.

4 Lag Bolt A full-bodied bolt with a hex head, spaced threads and a gimlet point. Types: Steel Electro-plated Zinc- For use in wood in non-corrosive environments. Steel Hot-Dip Galvanized- For use in corrosive environments. Stainless- Has superior corrosion resistance to galvanized steel bolts.

5 Wood Screws They have a wide range of purposes usually mainly for cabinetry . Phillip flat head, Slotted flat head - These type of screws are made too countersink into the material for a smooth surface area. Slotted oval head wood screw- This type of screw is basically the same thing as a flat head except, it is given the oval head for a more finished look. Slotted round head, Phillip round head- The round is used too protrude above the surface of the material to be fastened.

7 Metal Screws This type of screw is used for metal materials. Being that they are flat heads, they are usually not put through anything. Slots are probably already made for their shape and size. When using them, it is necessary that you use tweezers or a needle nose pliers too put them into place.

9 Hex Head Screw A hex cap screw is a cap screw with a hexagonal head, designed to be driven by a wrench. A compliant cap screw has somewhat tighter tolerances than a hex bolt for the head height and the shank length. The nature of the tolerance difference allows an hex cap screw to always fit where a hex bolt is installed but a hex bolt could be slightly too large to be used where a hex cap screw is designed in.

11 Carriage Bolt A carriage bolt or coach bolt has a domed or countersunk head, and the shank is topped by a short square section under the head. The square section grips into the part being fixed (wood), preventing the bolt from turning when the nut is tightened. A rib neck carriage bolt has several long stride ribs instead of the square section, to grip into a metal part being fixed.
