0.7mm 2H Lead Refills, 144 Pack

These Pentel 502HBX refills supply 144 pieces of 0.7mm 2H graphite in a single pack. The Super Hi-Polymer formulation is engineered for extra strength and reduced breakage during writing or drafting. They fit standard mechanical pencils that accept 0.7mm leads. The 2H grade produces a lighter, precise line suited to technical work.

Super Hi-Polymer formulation and 2H grade

The patented Super Hi-Polymer process minimises breakage and smudging, so fewer leads snap while advancing. A 2H hardness leaves a lighter imprint than HB or B grades, keeping drawings clean and lines sharp. Each lead measures 2.40 inches in length, giving extended use per stick. The medium point type maintains consistent width across the pack.

Suited to technical drawing and frequent writers

Ideal for drafters, engineers, students and anyone who prefers a hard, fine line that resists smudging. The 144-count pack reduces reorder frequency for heavy users. Not intended for artists seeking softer, darker strokes or for pencils that require a different lead diameter. Buyers who want more storage or a broader grade range should look at other assortments.

Questions about this item

How often will I need to replace the 0.7mm 2H leads in this 144-count pack?

Each pack contains 144 leads at 2.40 inches long. Replacement frequency depends on your writing pressure and daily volume; heavy users may go through a pack faster than occasional writers.

What is the first limitation I will hit when writing continuously with these 2H leads?

The 2H grade produces a lighter imprint, so very dark or bold lines require more passes. The Super Hi-Polymer formulation resists breakage, but the harder grade can feel scratchy on rough paper.

Do the 0.7mm leads generate any dust or heat during all-day writing sessions?

No heat is produced. The patented Super Hi-Polymer process minimises breakage and smudging, so dust is minimal compared with standard polymer leads.
