How do I measure the length of a screw?
The length of a countersunk screw is measured with the head. For all other heads, the length is measured under the head.
How to determine the diameter of a UNC or UNF screw:
The number of threads per inch will determine the diameter of the screw or nut of an American UNC or UNF screw.
Simply count the number of threads per inch (i.e. 25.4 mm) and refer to the table below.
For diameter 1 inch: 8 threads for 1 inch (25.4 mm) = UNC THREAD
