## Description

DYKEM TUFF GUY 44401 is a yellow heavy-duty industrial permanent marker designed for harsh industrial conditions. It features a reliable valve-action ink system paired with a medium felt tip to produce striking, high-contrast yellow marks. Widely used for part identification, batch traceability and QC marking on machining parts, automotive components, aerospace workpieces and tooling gauges. Standard packaging: 48 markers per case.

## Features

Excellent chemical resistance and solvent resistance: The ink is highly resistant to most industrial coolants, cutting fluids, degreasing baths and common solvents. Markings will not be easily wiped away or dissolved in harsh machining environments.

Ultra-fast drying for higher efficiency: The fast-drying formula achieves touch-dry within 25~35 seconds on most smooth surfaces, greatly reducing waiting time and smudging on production lines.

Wide material compatibility: It works not only on various metals (steel, aluminum, iron), but also leaves clear, durable permanent marks on smooth surfaces such as plastic, rubber, glass, wood and composite materials.

Heavy-duty durability with replaceable tip: Robust barrel construction withstands rough workshop use. The valve-action dispensing design delivers consistent ink flow, and the felt tip is interchangeable and replaceable to extend service life.

Safer eco-friendly formula: Non-xylene based formula with relatively mild odor, meeting modern industrial requirements for operator health and environmental protection.
