## Can you put any size lead in a mechanical pencil?

Mechanical pencil mechanisms use only a single lead diameter. Some pencils, such as the Pentel Function 357, place several mechanisms within the same housing, so as to offer a range of thicknesses (in this case three: 0.3, 0.5 and 0.7 mm). 1.00 mm leads also exist, but they are very rare.

Mechanical lead pencils use standard #2 lead, which is made from graphite, so it’s able to be used for standardized tests and other uses that require this type of lead. Popular brands include BIC mechanical pencils and Pentel mechanical pencils.

### Can you use 0.5 lead in a 0.7 pencil?

Can you use 0.5 lead in a 0.7 pencil? No, you can’t. Since the 0.7 mm pencil was designed for a 0.7 mm lead, the 0.5 mm lead would slip through the tip. The lead wouldn’t stay in place if you tried to write anything, and it might even fall out of the pencil.

Which lead is darker HB or 2B?

With varying ranges, shades and hardness of the pencils, terms such as 9H and 9B are used, where 9H is the hardest lead and 9B is the softest lead used in pencils. The HB pencils come in the middle range of the shade chart….

HB 2B
Definition The term HB stands for “hard black”. The term 2B stands for “soft black leads”.

## What makes a #2 pencil so special?

Pencils numbered higher than 2 have harder leads and are often used by engineers, architects, and draftsmen because of their harder points. The underlying logic here is that the harder point gives the user greater control of the lead.

What is darker HB or 2B?

The 2B pencil has a higher blackness, and the marks drawn are relatively black, while the HB pencil has a lower blackness, and the color of the marks drawn is relatively light, which is very different. 2B pencil is darker in color and lower in hardness.

### Which is the best lead to use for a pencil?

0.5 mm and 0.7 mm leads are the most popular, and they’re available in the widest selection of brands and lead grades, too. If you’re not sure which lead size to pick, these two are a good place to start. Here are our recommended uses for each lead size:

What’s the best size for a mechanical pencil?

0.5 and 0.7 mm are the most common sizes of mechanical pencil leads. They’re often used for general writing, but they’re also small enough to draw details. Both of these sizes are thick enough to have good break resistance, but you may prefer a 0.7 mm lead if you tend to press hard.

## What kind of lead should I use for a drawing?

You might use 0.5mm lead for writing or drawing. Overall, it’s still a versatile size that might be just right for your writing needs. 0.7 mm lead is a thicker variety, which makes it suited to sketching and non-detailed work. You may also find this lead useful if you do long-hand drafting.
