How does the 80/20 rule work?

The 80-20 rule, also known as the Pareto Principle, is an aphorism which asserts that 80% of outcomes (or outputs) result from 20% of all causes (or inputs) for any given event.

What is the difference between a lag bolt and a lag screw?

Although these terms are used interchangeably, lags should technically be referred to as a screw and not as a bolt. A bolt is a fastener with machine thread that can accept a nut.

What is the strongest wood screw?

In the first group, trim head screws and bugle head screws have heads designed to automatically sink flush in all but the hardest materials (e.g., rosewood, ebony). Bugle head screws drive in quickly and have good holding power in most materials.

How do I choose a screw size?

The most important factor in screw selection is length. The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge. Screws come in gauges 2 through 16.

Why is it called cheese head screw?
