Milwaukee 86697 Thermomelt Temp Indicating Stick 350F

Product Description

The MILWAUKEE 86697 is a Thermomelt temperature indicating stick used to measure surface temperatures quickly and accurately without electronic instruments. Rated to a maximum of 350 degrees F, it is accurate to within plus or minus 1 percent of the rated Fahrenheit temperature. When applied to a surface, the mark appears dull and chalky. Once the target temperature is reached, the mark melts to a glossy, transparent liquid, giving a clear visual confirmation. The larger-format stick design extends service life compared to previous generations while maintaining the same proven reliability. Made in the USA.

This temperature indicating stick is suited for industrial and trade applications including annealing, forging, welding, bending, and forming operations. Any situation requiring a fast, low-cost surface temperature check is a valid use case. HVAC technicians, welders, pipefitters, and sheet metal workers commonly use heat sticks during fabrication, heat treatment, and material forming processes where surface temperature control is critical to part quality or code compliance.

Key Features

• Maximum rated temperature of 350 degrees F with accuracy to within plus or minus 1 percent of rated Fahrenheit temperature
• Visual confirmation: mark transitions from dull and chalky to glossy and transparent at target temperature
• 33 percent larger and stronger construction compared to prior design for extended service life
• Low-cost, no-power surface temperature measurement with no calibration required
• Suitable for annealing, forging, welding, bending, and forming applications
• Made in the USA

Compatibility

Designed for general surface temperature indication across metal fabrication, welding, and heat treatment applications where a maximum temperature threshold of 350 degrees F must be confirmed.

Installation Notes

Temperature indicating sticks are applied directly to the work surface before or during heating. Allow the marked surface to reach temperature gradually and observe the mark for the phase change from chalky to glossy. Do not apply the stick inside open flames or directly to energized electrical components. Welders and fabricators should follow applicable workplace safety standards when working near heated materials.
