#14 is close to, but not exactly the same as, 1/4-inch.) The major diameter in Unified threads = 0.060″ + 0.013″ x (numbered diameter). So #2 has a major diameter of 0.086″. … We see that #14 would be 0.242 inches and #1/4 is 0.250 inches.

These screws are commonly made out of stainless steel or zinc coating.

What is UNC screw?

The Unified Thread Series is classified into coarse threads, fine threads and extra fine threads much like Metric screw threads are. UNC: Is the symbol for Unified coarse pitch threads. UNF: Is the symbol for Unified fine pitch threads. UNEF: Is the symbol for United extra fine pitch threads.

What is the screw pitch?

The pitch of a lead screw is simply the distance (spacing) between adjacent threads. Many standard thread designations express this as TPI or Threads Per Inch. Threads per inch are the reciprocal of the pitch. For example, in a ½-10 thread, the number of threads per inch is 10.

What are the different types of screw threads?

There are Standard threads, ACME threads, Buttress threads, and Square threads. Each of these threads may be used in clamps and vises for different reasons.
