The C.H. HANSON 25150 is a 27-piece reverse stamp set designed for marking steel, aluminum, and other metals with permanently readable impressions. Each steel stamp produces a mirror-image character that reads correctly when transferred through a stamping or printing process. The set covers the full alphabet plus common symbols, with each stamp measuring 2.75 inches in length and a 0.375-inch shank diameter. The 0.125-inch character size suits applications requiring precise, legible marks in tight spaces. Stamps are stored in a plastic case that keeps the set organized and protects individual pieces between uses.
Reverse stamp sets are used in metalworking shops, manufacturing facilities, and fabrication environments where parts require permanent identification, date codes, or traceability markings. The reverse orientation is standard for die-making, embossing, and transfer marking operations where the finished impression must read forward. This set is appropriate for use by tool-and-die makers, machinists, quality control technicians, and maintenance professionals who need consistent character depth and alignment across repeated stamping operations.
Designed as an OEM-style replacement or supplemental set for use with standard 0.375-inch shank stamp holders and alignment fixtures common in metalworking and fabrication applications.
Reverse stamps are driven by hammer strike or arbor press and should be used on a solid, flat backing surface to ensure consistent impression depth. Secure the workpiece before stamping to prevent movement and uneven character depth. Inspect shank condition before use and replace any stamp with a mushroomed or cracked shank. Personal protective equipment including safety glasses is required during all stamping operations.
