Answer
To tap a screw or bolt of this size, use the following drill bit: Decimal inches are measured in decimal inches.
8mm-1.00mm 7.1mm .
2795 5/16-32 NEF NEF NEF NEF NEF
9/32″ .
2812s9mm-1.25mm 7.9mm .
3110 3/8-16 NC 3110 3/8-16 NC
5/16″ .3125
Then, what drill bit size is the closest match to the number 5 16?
The chart below shows the decimal-fraction equivalents of the fractional-inch drill bit sizes that are most significant to fractional-inch drilling (that is, 0 to 1 by 64ths). (There are decimal places for.) 25 decimal-fraction equivalents are provided.

What’s more, how much larger should a hole be than the diameter of a bolt?
When drilling a tight fit hole, use a drill bit that is 1/32 inch bigger than the bolt diameter, and when drilling a loose fit hole, use a drill bit that is 1/16 inch larger than the bolt diameter.
Aside from the information provided above, how can I determine what size drill bit to use?
Hold the shaft of the drill bit up in front of the screw to prevent it from slipping. The threads of the screw should be the only thing that can be seen (and maybe a bit of the screw). It’s possible that the drill bit is too large if the threads aren’t visible. In this case, the screw is too large to be seen through the hole in the bit.

What size hole do you drill for a 1/4 Tapcon, and how big is the hole?
The diameter of the Tapcon screw to be installed determines the size of the Tapcon drill bit that should be used. When using the 3/16″ Tapcon, a 5/32″ diameter bit is required, and when using the 1/4″ Tapcon, a 3/16″ diameter bit is required.

Is the thickness of 5mm the same as the thickness of 3 16?
4mm is equal to 5/32 inch (which is little more than 1/8 inch). 5mm is little more than 3/16 inch. 8mm is equal to 5/16 inch. 9mm is nearly 3/8 inch in size.
Is it necessary to pre-drill deck boards?
Drilling Holes Before Drilling: The primary advantage of pre-drilling holes for deck screws, or any screws, is that it prevents the wood from splitting during the screwing process. When driving screws (or nails) near to the end of a board, this is sometimes the only method to keep the board from splitting.
What’s the difference between a tapered and a straight drill bit, and how do you use them?
The screw threads contact a straight bit pilot hole over their entire length, creating a tight fit. Second, when the screw goes near the bottom of the tapered pilot hole, the greater thread contact provided by the tapered hole provides for better thread engagement. As the hole becomes smaller, the threads penetrate deeper into the wood.
Do you pre-drill for Tapcons before you use them?
To install a Tapcon masonry screw, a hole must first be drilled into the brickwork and then tapped into place. To guarantee that the hole has the required tolerance, use a hammer drill to drill it. When the hammer drill is turned on, it must be in the hammer and rotation mode before it can be used for drilling. It is necessary to use a 3/16″ carbide tipped bit for the 1/4″ screw.

What is the size of pilot holes?
Generally speaking, the pilot hole should be at least as big as the screw’s minor diameter when working with hardwoods. Depending on whether the screw has deep threads or if the wood is very hard, the pilot hole should be an additional 1/64-in. bigger in diameter than the minor diameter. The pilot hole might be as small as 1/64-inch in diameter for softer woods.
