Screws

Screws are a type of fastener that is sometimes similar to a bolt and is typically made of metal and characterized by a helical ridge that is known as a male thread (external thread) or just thread. A screw is an inclined plane that is wrapped around a nail.

Anchor Screws
Anchor Screws are used to drill a hole the same size as the anchor body. You then push the anchor to its full depth in the hole. Then insert the screw through the item being fastened and screw it into the anchor tightly.

Cap Screws
Cap Screws feature a washer face under the head and a chamfered point, whereas a hex bolt does not have a washer face or chamfered threads. They are made of low carbon steel and are very common in construction or repair projects.

Concrete Screw
Concrete Screws tap threads into a predrilled hole in concrete, brick or block. Concrete Screws are designed and manufactured so the threads of the screw will tap threads into concrete, brick or block.

Drywall Screws
Drywall Screws are used to create threads as they are drilled into drywall without damaging the material. Among other tasks, Drywall Screws may be used to secure drywall to wood or to metal studs.

Eye Screw
Eye Screws are similar to wire eye lags, but are specified by trade size and are available in smaller sizes. They come in stainless steel, zinc plated steel and brass varieties.

Hexagonal Head Screw
Hexagonal Head Screws feature a washer face under the head and a chamfered point, whereas a hex bolt does not have a washer face or chamfered threads. They are made of low-carbon steel and are very common in construction or repair projects.

Machine Screws
Machine Screws have a uniform diameter the entire length of the shaft as opposed to the tapered screws, which have a pointed tip. Machine Screws are used to fasten machine components, appliances and more.

Self Drilling Screw
Self Drilling Screws are fasteners with a special pointed end style that allows them to penetrate thin materials without a starting or pilot hole. They are known as self-tapping screws or self drilling bolts, they cut or form threads to engage with the mating material.

Sheet Metal Screws
Sheet Metal Screws are designed for connecting thinner metal objects to one another or connecting metal to wood, plastic and other materials. Many can start their own pilot hole.

Tapping Screws
Tapping Screws are screws that can tap their 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
Wood Screws are specifically designed for connecting wood to wood. They usually require pre-drilled holes. Wood screws are a tapering metal screw with a sharp point.
