That doesn't change the grit (particle size) that passes through the mesh, at least until the thickness of the wires distorts the 3D shape of the holes so they no longer act like mostly flat square holes. What Is Sandpaper Grit Sandpaper grit is sized by a gauge number, with lower numbers signifying larger, coarser grits. But the holes have to meet minimum and maximum limits for the sieve #.įor a given hole size, you will have fewer wires/inch with larger wires. Any wire size that results in holes that fit the tolerance band for the sieve # is OK. The standard is all about the hole size, and it only suggests a typical wire diameter. If you follow the link to that E11 table and look at sieve #100, the nominal hole size is only 0.0059", which is quite a bit less than 0.100". If you want to know how large the particles that pass through a sieve of 100 mesh are, you consult the ASTM standard and see what it says. The holes are actually smaller because the wires have some thickness. When someone says 100 mesh, the hole sizes are very approximately 1/100" if you assume 100 wires/inch. It is the hole size, which is used to go/nogo particles passed on size. My point is that it is not the number of wires per inch that matters. In fact, 150-grit sandpaper is mostly for feathering areas that have already been sanded with a lower-intensity grit. 150-grit lacks the intensity for smoothing out nicks and stripping away multiple layers of paint. The problem with using a large wire size and trying to weave a small hole mesh is that the thickness of the wire prevents you from getting a properly shaped hole. The automotive sandpaper grit chart gets smoother with 150-grit, which leaves fine sanding marks on painted metals. You could punch the appropriately sized and shaped holes 1/4" apart in a piece of sheet metal and have a functionally correct mesh w.r.t. Click to expand.That is correct, so people can construct matching sieves to the standard sieves.
