Mechanical pencil leads GEKO 2.8 mm, 120 mm length, pack of 6

GEKO mechanical pencil leads with a 2.8 mm diameter and 120 mm length are replacement leads intended for thick-lead mechanical or propelling pencils. Supplied as a pack of 6 pieces, these robust leads are suitable for technical drawing, sketching and general marking where a wider, durable line is required. The leads are compatible with automatic pencils designed to accept 2.8 mm cores and provide consistent line width during use.

Advantages

These 2.8 mm leads offer increased strength and reduced breakage compared with finer leads, making them practical for heavy-duty marking and shading. Their 120 mm length extends working time between replacements, and the standardized diameter ensures compatibility with a range of thick-lead mechanical pencils. Supplied in a compact pack of six, the set offers straightforward replacement and storage for workshop, studio or classroom use.

Suitable for

• Technical drawing and drafting that require stable, wide lines
• Sketching and shading in art and design work
• General marking on paper, cardboard or templates
• Workshops, classrooms and field use where rugged leads are needed

Key specifications

• Lead diameter: 2.8 mm
• Lead length: 120 mm
• Quantity in pack: 6 pieces
• Lead type: solid graphite core suitable for thick-lead mechanical pencils
• Typical applications: drawing, sketching, marking

How to use

Ensure your mechanical or propelling pencil accepts 2.8 mm leads before inserting. Remove the pencil's cap or advance mechanism as required and insert a lead gently into the chamber until it seats. Advance the lead according to the pencil's design and adjust pressure and angle for desired line thickness and darkness. Replace the lead when it becomes too short or worn for stable marking.

Usage recommendations

Store leads in a dry place and handle them carefully to avoid snapping during insertion. For fine detail, reduce hand pressure or choose a finer lead type; for broader shading or heavy marking, use firmer strokes. Keep spare leads in the original pack to protect the ends and maintain consistent performance.
