Replacement Leads for Automatic Mechanical Pencil Högert Technik HT3B783 — HB

Replacement HB leads for automatic mechanical pencils designed for everyday writing, sketching and technical drawing. These spare refill leads are compatible with standard automatic/mechanical pencil systems and provide a medium hardness that balances darkness and durability. Packaged as refill sticks, the leads restore pencil performance and are suitable for school, office and workshop use where reliable, consistent line quality is required.

Advantages

The HB formulation offers a balanced combination of smooth writing and reasonable wear resistance, producing consistent lines without excessive smudging. The leads are manufactured to uniform thickness and straightness for trouble-free feeding in automatic mechanical pencils, reducing the risk of jamming or breakage. Their neutral grade makes them versatile across writing, note-taking, sketching and light technical drawing applications.

• Everyday writing and note-taking in school or office
• Sketching and preliminary drawings
• Technical drawing and drafting at a general level
• Replacing worn or broken leads in automatic mechanical pencils

How to use

Open the refill container and insert a single lead stick into the barrel of a compatible automatic mechanical pencil according to the pencil manufacturer's instructions.

Replace leads as they wear down or break to maintain consistent line width and quality.

Usage recommendations

Store leads in a dry place away from extreme temperatures to prevent warping or breakage. Use moderate hand pressure when writing to extend lead life, and consider a softer grade for darker shading or a harder grade for finer, longer-lasting lines if needed.
