Additional Discussion: Single-start threads are most common, and are more useful for general fastening needs. They offer more resistance to loosening than multi-start threads, due to the lower helix angle of the thread. Multi-start, aka: multiple-lead, is a thread that offers quick assembly and disassembly.

A cutting edge resource for generating customized running parameters from the experts behind the industry’s leading high performance end mills.

Proven to provide outstanding tool life and maximum material removal rates, these Nplus coated high performance end mills excel in High Efficiency Milling (HEM) of aerospace aluminum alloys with excellent performance in other non-ferrous alloys.

Using 20 thread-per-inch thread as an example, the screw must turn 20 revolutions to advance 1” in the part. A 1/4-20 double-start thread has the same number of threads per inch, but with two starting points, 180° apart, needs just ten revolutions to advance 1”. A triple-start thread, with starts 120° apart, will advance 3 times faster than a single lead thread. The result continues to change appropriately as additional starts are added.

Multiple start thread: a screw thread with two or more threads where the pitch is equal to the thread lead divided by the number of thread starts.  Also called multiple lead thread.

Helical designs and manufactures industry-leading products at competitive prices so you don’t have to settle for ordinary cutting tools.

Thread lead can be described as the linear screw travel accomplished in one revolution. Thread pitch is the distance from any point on a screw thread to the corresponding point on the next thread, measured parallel to the axis. With a single-start thread, lead and pitch are equal. A double-start thread's lead is twice the pitch measurement.
