Drywall screws are used to secure drywall or gypsum board, preventing crumbling or surface distortion. They are designed to secure to drywall to wood or metal surfaces. Most drywall screws have a fine tip and a tapered bugle head to penetrate drywall without damaging it. Their coarse, wide threads tightly grip both wood and plasterboard. Trim screws have small heads to join wood or composite materials while showing as little nail as possible

A chipboard screw or particleboard screw is a self tapping screw with a thin shaft and coarse threads. Chipboard is a made up of resin and wood dust or wood chips, so chipboard screws are made to grip this composite material and to resist withdrawing. The screws solidly fasten chipboard to chipboard or chipboard to other materials such as natural wood.

Self drilling screws are a commonly used variety of screw for quick drilling into both metal and wood. A self drilling screw can typically be identified by its point and flute (notch) tip. This tip acts as a drill bit for the screw making it much faster to install then having to switch between a drill bit and driver bit.

A self-tapping screw is a screw that can tap its own hole as it is driven into the material. For hard substrates such as metal or hard plastics, the self-tapping ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on a tap.

Wood screws have sharp crested, coarse, widely spaced threads . Being a thread-forming-type screw, they create their own mating threads during installation—no nut or tapped hole is needed. A gimlet point allows wood screws to start threading into wood easily : "A gimlet point is a threaded cone point usually having a point angle of 45 to 50 degrees." Threading is standard right-hand, so turn the screw clockwise to install.

Concrete screws, also known as masonry screws, are a type of fastener that holds one or more objects together or secures an object in place. They are commonly used to fasten certain materials, such as metal or wood, to concrete or masonry.

A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the tail.

A bolt is a type of threaded hardware fastener that is used to position two workpieces in specific relation to each other. Bolts come in several configurations for their application and specification variances. A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together.

A nail consists of a metal rod or shank, pointed at one end and usually having a formed head at the other, that can be hammered into pieces of wood or other materials to fasten them together.
