Pentel PEN502HBX 0.7mm 2H Lead Refill Box of 12

Product Description

The PENTEL PEN502HBX is a Super Hi-Polymer lead refill for mechanical pencils, offered in a box of 12 tubes with 12 pieces per tube. Each refill measures 0.7 millimeters in diameter and carries a 2H hardness rating, producing crisp, consistent lines suited to precise writing and drafting work. The polymer compound delivers smooth laydown with enough density to remain legible without excessive pressure. Individual leads are engineered for break resistance during normal use, reducing interruptions on the job or at the drafting table.

These lead refills are a practical supply choice for professionals and technical users who rely on mechanical pencils for field notes, blueprints, schematics, or general documentation. The 2H hardness produces finer, lighter lines than softer grades, making it well-suited for detailed linework where smearing and smudging need to be minimized. Each tube contains 12 leads, and the box unit holds 12 tubes, providing a volume supply appropriate for shop use, office stocking, or resale.

Installation Notes

Loading mechanical pencil leads requires no tools. Retract the existing lead or advance it fully through the tip before inserting a new lead into the magazine. Do not force leads into a jammed mechanism, as breakage inside the barrel can damage the advance assembly. Dispose of spent or broken leads safely to avoid contact injury.
