Example (inch, coarse): For size 7 ⁄ 16 (this is the diameter of the intended screw in fraction form)-14 (this is the number of threads per inch; 14 is considered coarse), 0.437 in × 0.85 = 0.371 in. Therefore, a size 7 ⁄ 16 screw (7 ⁄ 16 ≈ 0.437) with 14 threads per inch (coarse) needs a tap drill with a diameter of about 0.371 inches.
On the Drill and tap size chart, the chart shows a 10-24 tap uses a #25 drill. I am using a 10-23NF tap and both the tap and drill indes and a drill and tap set I bought from Home Depot made by Irvin use a #21 dirll. Is the difference because of the threading??? Robert Heard <email removed> Yes. See here--Coolhandscot 07:36, 19 August 2006 (UTC)
The major river in Ethiopia is the Blue Nile. However, most drinking water in Ethiopia comes from ground water, not rivers. Ethiopia has 12 river basins with an annual runoff volume of 122 billion m 3 of water and an estimated 2.6–6.5 billion m 3 of ground water potential.
One aspect of this method of sizing is that the size increment between drill bits becomes larger as bit sizes get smaller: 100% for the step from 1/64 to 1/32, but a much smaller percentage between 1 47/64 and 1 3/4. Drill bit sizes are written as irreducible fractions. So, instead of 78/64 inch, or 1 14/64 inch, the size is noted as 1 7/32 inch.
To calculate the major diameter of "aught" size screws count the number of extra zeroes and multiply this number by 0.013 in and subtract from 0.060 in. For example, the major diameter of a #0000 screw is 0.060 in − (3 × 0.013 in) = 0.060 in − 0.039 in = 0.021 in.
The success of Kana TV, was largely built on the fact there was a large untapped market for foreign content, particularly Turkish dramas, in Ethiopia. [ 4 ] In March 2017, Kana TV released its first independent TV market study which found that since its launch a year earlier, Kana TV had gained a 34% market share and had 8 of the top 10 highest ...
Walta TV was launched on April 7, 2017. [1] As of 2017, it was one of five channels in Ethiopia to be officially licensed by the Ethiopian Broadcasting Authority. [2] Before the launch of its own channel, Walta mostly provided its locally produced news and documentaries for the national broadcaster EBC (formerly ETV).
