## What does #3 pencil mean?

## What does #3 pencil mean?

The hardness of the graphite core is often marked on the pencil — look for a number (such as “2” “2-1/2” or “3”) — and the higher the number, the harder the writing core and the lighter the mark left on the paper.

## Is there a number 1 or 3 pencil?

Lead pencils are graded on a scale from No. 1 to No. 4 based on how much graphite is inside the core. The #1 pencils are the softest, while the #4 pencils are the hardest.

**What is a #2 pencil?**

Pencils above number two are filled with harder graphite and tend to have lighter markings and are frequently used in draughting pencils, often used by architects and designers. A number two pencil on the numeric scale is roughly equivalent to an HB pencil on the international scale.

**What is the darkest pencil number?**

B9 is the softest and darkest. 9H is the lightest and hardest graphite pencil. So a B6 is softer and darker than a B2. An 6H is harder and lighter than a 2H and much harder and lighter than a HB or a B pencil.

### What is a 4B pencil?

“B” pencils feature softer graphite. (The “B” stands for “black”.) The number found in front of the letter reveals just how soft or hard the pencil is. In other words, a “4H” pencil is harder than a “2H” pencil while a “4B” pencil is softer than a “2B” pencil.

### What is a 3B pencil used for?

A 3B provides both wider, blacker text, and that smoothness that allows the pencil to glide on the page. Darker pencils glide even more – at least most of them; this depends on the brand – but they wear out very quickly, and need to be sharpened every couple of minutes.

**What size lead is a #2 pencil?**

Generally, an HB grade about the middle of the scale is considered to be equivalent to a #2 pencil using the U.S. numbering system.

**What is the difference of 2B and 3B?**

The 2B Thread has wide application, accommodates plating, finishes, and coating to a limited extent and, therefore, has fair tolerance allowances. Class 3B Thread means a 3A screw in a 3B nut or threaded hole for applications that are close to tolerance limits.
