Pica Dry 4030 Black Lead Refill is a pack of graphite replacement leads for the Pica Dry automatic marker system. This is a mechanical pencil refill designed for marking on almost all common jobsite surfaces. Model Number: 4030. If you already rely on a Pica Dry marker for layout work, these refills are the part that keeps it useful instead of turning it into a dead holder in your pouch.

The big reason tradespeople buy this refill is surface versatility. Source data lists it for use on dry, wet, glossy, rough, oily, and dusty materials, including stone, concrete, metal, wood, wet and dry lumber, polyvinyl chloride pipe, glass, tile, rubber, and cardboard. That is the real value here. You are not swapping between a carpenter pencil, soapstone, and a paint marker every time the material changes.

The graphite formula is water soluble and removable with a damp cloth on glossy surfaces. That gives you a cleaner option for temporary layout lines where you need visibility during fitting or installation but do not want permanent marks left behind. For finish work, metal fabrication, tile fitting, or any install where cleanup matters, that is a practical advantage over standard pencil lead.

The 2.8 mm lead size is well suited to the Pica Dry system because it balances visibility and control. It is thick enough to survive real jobsite handling better than a thin drafting lead, while still giving you a usable line for layout and transfer marks. Since the pack includes pre-sharpened leads, you can load them quickly and get back to work without fussing around.

Compatibility is straightforward: these refill leads are made for use with the Pica Dry automatic pencil, listed in source data as for use with PA3030/SB. If you are running that marker body already, this is the correct consumable to keep on hand. That makes this a simple but important accessory for anyone who uses the Pica system daily.

Who should buy it? Carpenters, remodelers, metalworkers, tile installers, electricians, plumbers, and general contractors who mark a wide mix of materials. It also makes sense for serious DIY users who want one marking system that works beyond plain lumber. If your work moves between rough framing stock, finished surfaces, sheet metal, pipe, or masonry products, these Pica Dry refills solve a very common problem: making a mark that actually shows up where you need it.
