okay, let's dive into the world of bolt sizes, thread mechanics, and the mathematics behind them. this guide will cover everything from understanding bolt sizing conventions to calculating thread engagement and using python code snippets to automate these calculations.

*part 1: understanding bolt sizing conventions*

bolts are essential fasteners used in countless applications, from structural engineering to electronics. understanding how they're sized is crucial for selecting the right bolt for the job. bolt sizing systems primarily fall into two categories: metric and imperial (also known as unified).

*1.1 metric bolts:*

*designation:* metric bolts are designated using the letter "m" followed by a number representing the nominal diameter in millimeters (mm). for instance, "m8" indicates a bolt with a nominal diameter of 8mm.
*thread pitch:* after the diameter, the thread pitch (the distance between adjacent threads) is specified in millimeters. for standard coarse threads, the pitch is often omitted as it's implied for common sizes. if the pitch is different from the standard, it's explicitly included. for example, "m8 x 1.25" denotes an 8mm diameter bolt with a 1.25mm thread pitch.
*strength class:* a strength class is indicated by two numbers separated by a decimal point (e.g., 8.8, 10.9, 12.9). the first number represents the tensile strength in mpa (megapascals) divided by 100. the second number, when multiplied by 10, gives the yield strength as a percentage of the tensile strength.
*tensile strength (uts):* the maximum tensile stress a bolt can withstand before breaking (measured in mpa or psi). for an 8.8 bolt, the tensile strength is 800 mpa.
*yield strength (ys):* the stress at which the bolt starts to deform permanently (measured in mpa or psi). for an 8.8 bolt, the yield strength is 0.8 * 800 = 640 mpa.
*example:* "m10 x 1.5 - 8.8" represents a metric bolt with:
nominal diameter: 10 mm
