Hole Sizes for Cut Tapping

After tapping, the hole size should fall within the Spiralock recommended minor diameter range for cut threads. • If the ﬁnal minor diameter is below the range for a cut thread, use a larger drill. Do the opposite for a ﬁnal minor diameter that is larger than the recommended range for cut taps. Fractional Thread Size Minor Dia. Min. (in)

Spiralock Thread Form Taps | Cutting Tool Engineering

The Spiralock thread form solves thread loosening and joint integrity issues by changing the physics of how the threads interact. In traditional 60-degree threads, the gap between the upper edges of the male and threads can lead to vibration-caused thread loosening. Stress concentration and fatigue at the first few engaged threads is ...

Anyone tapping Spiralock threads?

This thread profile is unique to Stanley Spiralock and requires their very expensive taps/thread gages. We don't have any experience with this thread profile and are limited to the few different styles of taps they produce, due to the volume of holes we were leaning towards a cut tap vs thread mill.

Spiralock® Thread Turning

Spiralock ® Thread Turning Carbide Inserts. Thread turning is another option for making internal threads when tapping conditions are not optimal, such as parts with large diameters or in difficult-to-cut materials. Thread turning is most often performed on a lathe with a cylindrical workpiece and uses an indexable carbide insert with a boring bar.

Different Types of Threaded Locking Methods for Secure Connections

Spiralock threading puts a shoulder which is ground to a slightly different angle on the entire screw thread so the entire bolt or screw gets compressive loading along its shaft, locking it in place by friction when the screw is tightened, while still permitting easy turning until it is tightened.
