Pentel 0.5 mm HB lead refills

These Pentel Super Hi-Polymer leads fit 0.5 mm mechanical pencils and come in tubes of twelve. The HB grade matches a standard No. 2 pencil for darkness and is guaranteed to scan on test sheets. A patented process makes each 60 mm lead stronger and smoother with minimal breakage.

Suited for exams and daily writing.

Students and professionals who need reliable scanning performance on standardised forms will appreciate the consistent dark line. The 0.5 mm size works well for fine detail and general note-taking. Users who prefer broader strokes or softer grades should consider other options.

0.5 mm diameter decides fit

The single specification that determines compatibility is the 0.5 mm lead diameter. Only mechanical pencils designed for this exact size will accept these refills. The HB hardness and black colour are fixed for every stick in the tube.

Questions about this item

Which mechanical pencils accept these 0.5 mm leads?

Any mechanical or automatic pencil designed for 0.5 mm diameter leads will accept these refills.

Will the HB darkness match the older #2 pencils I still use for exams?

Yes, the HB grade is equivalent to a #2 pencil and is guaranteed to scan on standardized tests.

How can I confirm the leads are feeding correctly after I load the tube?

Advance the lead; it should extend smoothly, write a dark consistent line, and resist snapping under normal pressure.
