Dykem 40001 Oil-based Broad Point Marker Blue

Product Description

The DYKEM 40001 is an oil-based layout and marking marker with a broad tip, designed for use on metal, glass, wood, and other hard surfaces common in trade and industrial environments. The oil-based ink formula resists wiping and provides high-visibility blue marks that hold up during fabrication, inspection, and layout work. The broad point delivers bold, easy-to-see lines suited for marking stock, labeling components, or scribing reference points on the shop floor or in the field. This marker is a standard hand tool for machinists, pipefitters, ironworkers, and general tradespeople who need a reliable surface marker.

The DYKEM 40001 is used across a wide range of trade applications including metal fabrication shops, mechanical rooms, plumbing rough-in, structural steel work, and HVAC equipment staging areas. It is suited for any environment where permanent or semi-permanent surface identification is needed on parts, fittings, pipe, conduit, or equipment housings. The oil-based ink makes it appropriate for use on both dry and lightly oiled metal surfaces.
