Obviously not! The screw size will vary according to the type of hinges and door material. For instance, If you have a wood front door, choose number #9 between 1.5-inch and 2.5-inch long screws, depending on the door size and weight. Metal doors are super heavy and require large diameter number #12 screws. In contrast, a small diameter number #6 screws of 5/8 inches are perfect for loose cabinet doors.

In our article below, we have highlighted a variety of screws for door hinges and their sizes accordingly. We have also answered all the frequent queries to clear up the misconceptions. Be very wise as a wrong decision can have a remarkable negative impact on the overall security of the door.

What Size Screws to Use for Door Hinges?

The screw size, specifically its diameter and length, will solely depend on the hinge of the door.

Length:

Most house door screws are around 7 or 8 gauge long. If you go through the market, you will come across a huge variety of 8-gauge screws. According to our research team, it is best to go for screws minimally one inch long compared to the door hinges.

Many users may even choose screws of 1.25″ or 1.5″. Be very wary while determining the length as it is responsible for superior durability between the door hinge and joists. In fact, it may have an impact on the overall security of the door.

Diameter:

Screws generally feature a shank hole and a head bore. The Shank hole is basically the sharp portion of the screw. An 11/32 inches bore is typically compatible with door hinges.

On the contrary, the shank-holes are around 5/32 inches. Never go for a low-diameter screw, as it will loosen up the door eventually.

7 Gauge Screw 8 Gauge Screw 
Size Of the Head Bore 5/16 11/32
Shank Hole Size 7/64 7/64
Length 3/8 to 1-1/2 1/2 to 2

Before determining the screw size to hang a door, a house owner must be clear about the material & type of the door as well. Apparently, the size of the screw needs to be increased with an increase in weight & durability. For instance, if you own a metal door, you may have to choose large screws like number #12 or more.
