Tandem Taps - Where You Lead, I Will Follow

Tandem Taps - Where You Lead, I Will Follow

Tandem, originates from the Latin meaning “at length”, first seen in modern language in the late 18th Century to describe any two things working together, “in tandem”.

 

Close your eyes and say the word “Tandem”. What do you see? A bicycle built for two? A stroller made for two children? What about a semi-truck pulling two trailers down the highway? The more adventurous might envision a tandem sky-dive or a 2-person kayak.

 

For this blog, I will concentrate on Tandem Taps. This may not sound as fascinating as the examples already shared, but some knowledge is worth the pain. Tandem taps are a special type of tap that includes two or more threaded sections for creating internal threads.

Acme vs. Trapezoidal Threads - What's the Difference?

Acme vs. Trapezoidal Threads - What's the Difference?

Acme threads appeared sometime in the late 1800's, as an improvement on the square thread form. Square threads were the first choice for motion transfer and heavy loads. But, square threads were difficult to produce with available cutter technology. Although the square form was relatively efficient for the purposes required, it was inherently weak at the base of the thread due to the sharp 90-degree angle of the flank. Modifying the included-angle to 29-degrees widened the base of the thread making it stronger. Over time, standards in Acme diameters and pitches were established, all with Imperial Inches in diameter and Threads-per-Inch units of description.
