Not solely are there many varieties of screws and screwheads, there’s an intricate quantity of totally different elements of a screw.
Take a look at our customized diagram above which clearly signifies every half.

Who knew there was a lot concerned in designing and making a screw.
Listed here are transient descriptions of every half.
Drive: That is the slot the place your screwdriver tip goes. It’s additionally known as a screw head. There are a lot of such choices; accordingly there are a lot of screwdriver ideas you must have in your toolbox.
Head: The top is the highest of the screw. It’s usually wider than the shank and thread. Heads will be flat or domed. Some have a small diameter in relation to the shank and others are very extensive.
Thread size: The thread size is both full size or partial. Accordingly, there are full thread and partial thread screws.
Why would you utilize a partial thread screw? It’s stronger within the sense that the non-thread half is stronger with out weak spots. When you could bolt one thing along with most energy, a partial thread screw or bolt is greatest. Read all about this here.
Level: The purpose is clearly the place the screw enters no matter materials you’re placing the screw into. If no level (i.e. flat tip), it’s a bolt which requires a pre-made gap.
The thread: Amazingly, the thread has many parts and varies amongst screws. There’s the thread angle which is how steeply it angles down.
There’s additionally distance in between threads that make a distinction. That is the pitch. Some screws have thread which are small and shut collectively. Different screws have bigger threads spaced additional aside (i.e. drywall anchors).
Screw thickness (minor and main diameter): There are two measurements with regards to screw thickness. There’s minor and main diameters. The most important diameter is the diameter on the thickest half of the thread (i.e. outer half of the thread, a.ok.a. the crest). The minor diameter is the thickness on the base of the screw (think about if the thread was stripped, the remaining shaft could be the minor diameter).
Crest: Crest is the tip and valley of the thread.
