If you’re planning to install one or more hinges, you’ll need to choose the right screws. With the exception of weld-on hinges, most hinges are mounted with a set of screws. They feature several holes on each leaf. You can install a hinge by driving screws through these holes and into the adjacent material of the door or frame.
Length
You can’t choose the right hinge screws without considering the length. Some hinge screws are 1.5 to 2 inches long, whereas others are over 3 inches long. Hinges, of course, must be able to support the weight of the doors, gates or other objects with which they are used. Long screws typically provide greater support for hinges than short hinges.
Shank Threading
Like all screws, hinges crews feature threading. Threading consists of helical notches on the shank that allow screws to scoop out and remove material from the objects in which they are driven. Hinge screws, however, often have a partially threaded shank rather than a fully threaded shank. The top part of the shank is smooth. and is proceeded by the threaded portion. Partial threading such as this allows screws to create a strong grip.
Thread Diameter
Don’t forget to consider the diameter of the threading as well. Hinge screws are available in different thread diameters, which affects their overall width. The greater a screw’s thread diameter, the wider the screw will be.
Common thread diameters for hinge screws, in American sizes, include #8 and #10. The former has 0.16-wide threads, whereas the latter has 0.19-wide threads. The thread diameter must be narrow enough to fit through the hinges’ holes, but it should also be wide enough to grip the material in which it’s driven.
Material
Hinge screws are available in different materials as well. Some of them are made of brass, whereas others are made of stainless steel.
Brass hinge screws are softer than their steel counterparts, but they are lightweight and offer a rustic appearance that many people prefer. Steel hinge screws, though, are prized for their strong and durable properties. Consisting of an iron alloy with carbon, stainless steel can withstand moisture without rusting.
Head
You should also consider the head type when choosing hinge screws. Not all screw heads are the same. They are available in different drive types, such as Phillips and slotted. Some screws also have a flat or recessed head, whereas others have a Truss head. Most hinge screws, though, have a Phillips drive type with a flat or recessed head.
