Now, if we have the pitch and we want to know the diameter of the screw, then from the previous formula we must have the diameter (D), like this:
Let’s apply the above data to check if it is correct:What diameter (D) should I turn the screw with if I need the pitch (P) to be of 7 mm.?
Since 2020, the investing legend has dumped many financial, drug and airline stocks — not long after buying them for the first time.
Between 1965 and 2023, Berkshire Hathaway's stock portfolio posted a 19.8% compound annual gain. That is nearly double the 10.2% return of the S&P 500 index, with dividends included.
However, Buffett continues to prioritize finding and buying quality stocks at a fair price — and holding them for the long term. He patiently builds those stock positions over time.

D’ is the diameter to turning the nut, it is equal to d+ 0.125Pe’ is the thickness of the span of the nut, it is equal to e + 0.05 to 0.1
In the prior Q2, Berkshire chopped its position in Apple nearly in half, also cutting stakes in Chevron (CVX) and several other stocks. It added to Occidental Petroleum (OXY), while exiting Paramount Global (PARA) and Snowflake (SNOW).
Now let’s assume that the screw is a two start screw, then:Tan α =(Pn)/(πMd)Tan α = 5(2)/(3.1416(22.5))Tan α = 10/(70,686)Tan α = 0.141470729α = tan ¯¹ (0.141470729)α = 8.052240379α = 8° 3’ 8’

In the third quarter of 2024, Buffett's Berkshire further slashed its massive Apple (AAPL) position, the company's 10-Q filing revealed on Saturday. Despite a 25% position cut in Q3, Apple stock remains one of the largest holdings in Berkshire's closely watched investment portfolio.
In this way, the two cutting tools have an angle α that allows the cutting tool not to damage the fillet of the screw when it passes through it. To calculate this angle we will take into consideration the following:

You need to keep up on Warren Buffett stocks, because while the Berkshire Hathaway (BRKB) chief sticks to a winning investing formula, that doesn't mean sitting still.
Apple stock is among the top five holdings in Berkshire Hathaway's portfolio by number of shares. But it is easily No. 1 by market value.
Calculate the angle of the cutting tool so that it does not damage the fillet of a single start screw, pitch 5 mm, outside diameter 25 mm and inside diameter of the screw 20 mm.

As of October, these are the top stocks in Berkshire's portfolio by number of shares, based on regulatory filings tracked by whalewisdom.com:
D, the outside diameter of the screw, is equal to P/0.2P, is the pitch of the screw, is equal to 0.2De, is the thickness of the thread, in the screw is equal to 0.5Ph, is the height of the thread, in the screw it is equal to 0.5Pd, is the inside diameter of the screw or bottom diameter, it is equal to D-2h
All told, Buffett and his team oversee around 50 stocks in Berkshire's equity portfolio, which is valued at more than $300 billion.

There is a type of thread called power transmission or high strength, its main feature is the profile of the tooth and its pitch, its main advantage: the low wear, strength and durability. Between this type of threads the most common is the Square Thread.
Find the angle α of the thread’s helix like this:If the thread is a single start, the following formula is used:Tan α = P/(πMd)
To avoid making screws of small diameter and big pitches or on the contrary, screws of big diameter and small pitches, this relation has been normalized or standardized and it was established that to keep a proportion between the diameter of the screw and the pitch, the latter is calculated based on the screw, and the formula to find the pitch is the following:

Apple now makes up 31% of Berkshire's total equity portfolio. That is down from 41% before the Q2 2024 cuts, but up from 6% in 2016.
