Jobsite-Ready Design A quiver cap and built-in sharpener make this industrial marker easier to carry, protect, and keep writing clean lines without digging around for extra accessories.

Overview

Pica Gel Signalmarker Black 8083/SB is a highly permanent industrial marker made for clear marking on hard-to-mark jobsite and shop surfaces. This is a paint crayon style marker designed for layout marking on metal, stone, concrete, wood, tile, glass, rubber, cardboard, and PVC pipe. Model Number: 8083/SB. If you need a black marker that keeps working when the surface is wet, oily, glossy, rough, or cold, this is the kind of marker you keep in your pocket instead of in the truck.

The big reason this marker matters is surface versatility. Source data calls out use on most surfaces, including dry, wet, glossy, rough, and oily materials. That makes it useful for fabrication, concrete work, mechanical trades, and general construction where clean conditions are the exception, not the rule. Instead of switching between different marking tools depending on the material, this marker is built to handle a wide spread of common jobsite surfaces with one tool.

The marking material is a solid paint-style gel that delivers bold, opaque marks. That matters when you’re working on dark materials or when layout lines need to stay visible after handling. The listed tip size of 2 to 8 mm gives you flexibility for broader marks and more visible layout work, especially on rough stock or uneven material where a fine marker line can disappear fast.

Pica also built this one with real-world practicality in mind. The quiver cap makes it easier to clip onto clothing or a pouch so the marker stays close instead of ending up at the bottom of a toolbox. A built-in sharpener helps keep the tip usable when you need a cleaner edge or more controlled marking. That is a small feature, but on the job it saves time and keeps you from treating the marker like a disposable item the second the tip gets rounded over.

Another strong point is durability under demanding conditions. Source data states the marking material can withstand temperatures up to 1832F and is low chloride. For users in metalworking and industrial environments, that is more than a throwaway spec. It means marks are suited for applications where heat resistance matters and where material compatibility can be important.

At 6.06 inches overall length, this Pica industrial marker is easy to carry and large enough to use with gloves on. It is a straightforward hand tool, but it is clearly aimed at people who need dependable performance rather than office-supply convenience. Contractors, welders, steel fabricators, masons, mechanics, plumbers, and serious DIY users will all understand where this kind of marker earns its keep. If you regularly mark dirty material, damp stock, or slick surfaces, this is a smarter choice than a standard shop marker.

Built to Mark Where Regular Markers Fail

This marker is made for the materials that usually ruin ordinary pens and markers. When the surface is slick, rough, damp, or dirty, the solid paint-style formula gives you a visible mark you can actually work from.

• Works on metal, stone, concrete, wood, PVC pipe, glass, tile, rubber, and cardboard
• Designed for dry, wet, glossy, rough, and oily surfaces

Visible Marks on Dark and Rough Material

On dark material, thin ink lines tend to disappear. The bold opaque marking style is easier to see, which helps when you are laying out cuts, part locations, or reference marks in poor lighting or on textured stock.

• Bold point type with a 2 to 8 mm tip size range
• Black ink color in a highly permanent gel signal marker format

Made for Pockets, Pouches, and Daily Carry

Small jobsite details matter. The quiver cap helps keep the marker accessible, and the built-in sharpener gives you a way to tune the tip instead of tossing the marker aside once the edge gets blunt.

• Includes quiver cap for carry and protection
• Built-in sharpener supports cleaner, more controlled marks
