Hard 3H leads for very precise, light technical lines in 0.5mm mechanical pencils

The Staedtler Mars Micro Carbon 250 05-3H is a 0.5mm 3H (hard) lead refill for Mars Micro 775 and compatible 0.5mm mechanical pencils, providing a harder and lighter line than 2H for very precise technical layout work and construction lines that must be extremely light.

3H is three steps harder than HB, producing a very faint, precise mark. It sits between 2H (the most widely specified technical hard grade) and 4H (approaching the extreme hard range). Some architects and technical drawing professionals prefer 3H specifically for preliminary layout lines that must be barely visible and easily erased, while 2H is used for standard layout. The Mars Micro Carbon break-resistant compound maintains integrity even at this harder grade in the fine 0.5mm format. Compatible with the Mars Micro 775 0.5mm and any standard 0.5mm mechanical pencil.

  • 3H grade - harder and lighter than 2H for very faint layout lines
  • 0.5mm diameter for the finest mechanical pencil technical line
  • Mars Micro Carbon break-resistant compound for the 3H grade
  • For preliminary layout lines that must be barely visible and erase cleanly
  • Compatible with Mars Micro 775 0.5mm and all 0.5mm mechanical pencils
  • Refill tube for convenient lead loading and storage
  • Technical drawing preliminary lines barely visible and easy to erase
  • Architecture layout work where lines must be even lighter than 2H
  • Refilling 0.5mm mechanical pencils with 3H for precision work
  • Very fine technical detail lines in drafting and illustration
  • Completing a hard grade range in studio lead supply
