4 Inch Stainless Steel Screws
To convert the decimal dimensions shown above to fractional dimensions, simply multiply by 64. The result will be the number of 64ths of an inch equal to the decimal dimension. For instance, the thread size on a 1/4-20 screw is given as .249'. Converting to a fraction, multiply by 64 (.249 x 64 = 15.936). The answer, 15.936, rounds to 16/64, or 1/4 of an inch.
