Accurate marking is essential in metal fabrication, welding, machining, and layout work. Tech Team’s #00943 Round Soapstone Pen Refills provide crisp, heat-resistant, non-permanent lines that stay visible through high-temperature operations. Whether you’re laying out cuts on steel plate, marking bend lines, or creating reference marks for machining, these soapstone sticks offer clean, reliable performance for professional shops and field crews. Soapstone is naturally heat-resistant, allowing marks to remain visible during welding, brazing, grinding, plasma cutting, and oxy-acetylene operations. Unlike ink markers or chalk, soapstone will not burn away, smear, contaminate welds, or damage the surface. It produces bright, legible lines that help guide cutting tools and ensure precise fabrication. Each stick measures 5" (125 mm) long and 1/4" (6.4 mm) in diameter, fitting almost all standard round soapstone holders and welding markers. These marking sticks glide smoothly across steel, stainless, aluminum, cast iron, and galvanized surfaces—even when they are rough, dirty, or oily. Because soapstone is non-toxic and non-abrasive, it is also safe for use on glass, ceramics, textiles, and other materials requiring temporary, easily removable markings. The 36-piece bulk pack provides long-lasting supply for fabrication shops, welding classrooms, maintenance departments, and on-site mechanical crews. Keeping extra refills available ensures that welders and machinists always have reliable marking tools ready when working in high-heat, fast-paced environments. Whether you’re cutting plate steel, prepping welding joints, laying out machine work, or guiding torch paths, Tech Team #00943 Round Soapstone Refills deliver consistently visible, heat-stable marking performance you can trust.
