How to determine screw thread count
WebScrew Thread Design Screw Thread Fundamentals A screw thread is defined as a ridge of uniform section in the form of a helix on either the external or internal surface of a … WebSince 10 square centimetres is 3.16cm x 3.16cm, this equates to 124 threads along the 3.16cm length, plus 124 threads along the 3.16cm width. Threadcount per 10 sq cm is therefore 124+124, which rounds up to 250. A ready conversion to remember is that Threadcount (Imperial) x 1.25 = Threadcount (Metric). More than just threadcount
