Pentel PEN50HB Lead Refill 0.7mm Hb Black 12 Count

Product Description

The PENTEL PEN50HB is a Super Hi-Polymer lead refill designed for mechanical pencils. Available in 0.7 mm diameter with HB hardness, these refills produce consistent, dark, and smooth lines suited for writing, drafting, and detailed drawing. Each tube contains 12 individual lead pieces, with the total writing length equivalent to 12 standard wooden pencils. The formula is engineered for high density and uniform line quality, reducing skip and breakage during use. This product is sold as a tube of 12 refills and is well suited for office, field, or workshop environments where reliable mechanical pencil performance is required.

These lead refills are appropriate for general writing, note-taking, sketching, and precision drawing applications. The 0.7 mm diameter is a widely used size in standard mechanical pencils found across professional and educational settings. The HB hardness rating places the lead at the midpoint of the hardness scale, making it versatile for both light notation and darker line work. Suitable for use by estimators, project managers, inspectors, and technicians who rely on mechanical pencils for field documentation and plan markup.

Installation Notes

Loading lead refills requires no tools. Follow the mechanical pencil manufacturer's loading procedure, which typically involves retracting the tip and inserting the lead into the lead magazine or feed tube. Avoid forcing or bending the lead during insertion, as this may cause breakage. Dispose of empty tubes and lead fragments according to local waste guidelines.
