8 Screw Size

8 Screw Size You asked about M3 M4 etc that describes only the outside diameter of the screw or the size of an unthreaded hole the screw would slip through A full description is like M6 1X25 Which describes the outer diameter 6 the distance from one thread to the next 1 pitch and the length 25 all in millimeters

If you wish to use a screw that is actually going to grip the material such as a wood screw or self tapping screw do not buy the item Instead you will need an appropriately sized 10 pilot drill 3 32 for soft wood 7 64 for hardwood and a separate countersink bit designed for your chosen screw size So the answer depends on the application If you want it to be very loose in the case of a bolt where you re going to have washers on both sides and a nut on the far side threads then feel free to upsize by a fraction in this case 6 16 or 3 8 If you re using a screw where you want the threads to be firmly bedded use the smallest drill bit you have in a soft material like wood

You need to make the hole the right size neither too big nor too small You should choose the size diameter and length of screw based on the job you are doing You should then choose the size of wall plug based on this The internal diameter of the wall plug is determined by the size s of screw it is designed to take If you have an identical screw you can probably take it to Home Depot or Lowes and use the thread gauge mounted in the hardware section The HD in my area has one but I m not sure if all of them do This website also has several printable size gauges for screws bolts washers and nuts Otherwise you can buy one

The diameter of the bit should provide a clearance hole for the screw i e slightly larger diameter than the O D of the screw Hole saws tend to make slightly oversize holes Stop as soon as you complete the hole through the tile bedding and backer board and switch to a standard twist drill for the smaller pilot hole in the stud GRK R4 Multi Purpose Screw 9 3 5 inches long GRK R4 Multi Purpose Screw 10 3 5 inches long BTW I own a Paslode Cordless XP Framing Nailer I will be doing some framing that will be inspected by the AHJ I would like to use GRK R4 Multi purpose screws for the framing of the 2 by X lumber Let s assume all fasteners are acceptable by the AHJ

The Phillips screwdriver size is based on the size at the very tip Based on diagrams of the tip from the original Phillips patent shown in one of the links to sizes I m guessing that the relevant physical size is the cross you see when you point the screwdriver at your nose as though it were a screw and look at it end on or something directly related to that So if you underlayment is 5 8 or 3 4 thick you can use 1 5 8 coarse thread screws You could use the same screws for thinner underlayment but the risk of hitting something unseen below the floor grows The typical screw spacing for underlayment NOT sheathing is 4 on the edges and 6 in BOTH directions in the middle
