Pentel 0.5 mm 2H Lead Refills

These 0.5 mm, 2H black leads fit standard mechanical pencils and come in a tube of twelve. The Super Hi-Polymer formulation is engineered for consistent line quality and reliable scanning on test sheets. Suitable for students, engineers, and anyone who needs precise, dark marks without frequent breakage.

Tube packaging and 60 mm length

The protective tube keeps the twelve leads organised and prevents damage inside a bag or desk drawer. Each lead measures 60 mm, matching the feed mechanism of most common 0.5 mm mechanical pencils. The rigid container allows quick single-lead dispensing during exams or drafting sessions.

Stronger core reduces breakage

Proprietary polymer bonding yields a harder, smoother core that resists snapping under normal writing pressure. Users experience fewer interruptions and less lead waste during extended use. The dark, consistent imprint remains legible for scanning equipment and archival copies.

Questions about this item

What diameter mechanical pencils accept the 0.5 mm C505-2H leads?

Any mechanical or automatic pencil designed for 0.5 mm diameter leads will accept these refills; the tube contains twelve 60 mm long 2H black leads.

How long is each lead so I know it fits my pencil cassette?

Every lead in the tube measures 60 mm, the standard length for 0.5 mm mechanical pencil cassettes.

Do I just drop the whole tube into the pencil or load leads one by one?

Remove the tube cap, slide the 0.5 mm leads individually into the pencil’s lead reservoir, then replace the tube cap to store the remaining leads.
