Fine thread screws are primarily used for attaching things to metal studs. The general rule of thumb I've heard is ONE INCH of penetration into the framing material, though some builders prefer 1  or 1  of penetration. Since your 2x6 decking is 1-1/2 thick, you can use 2-1/2 or 3 deck screws.There is not much benefit to using much longer screws, because the screws will usually break before they pull out of the wood.he general rule of thumb I've heard is ONE INCH of penetration into the framing material, though some builders prefer 1  or 1  of penetration.

The 8 refers to the size (diameter) of the screw, and the 32 means it has 32 threads to the inch. Most of the screws for mounting hinges are self-tapping (they tap their own mating threads in wood) type AB (they have more threads per inch and are more effective in brittle materials like wood than Type A).owever, most wood screws do not include the threads per inch measurement and would just be listed as 8 X 1. If the gauge number is not known, simply measure the diameter of the shank in inches and round to nearest listed number on chart below for screw number identification.
