The C.H. HANSON 21051F is a machine-made individual steel stamp used to permanently mark a capital letter F onto metal, wood, plastic, and other hard surfaces. The stamp features a 1/4-inch (6.4 mm) character size, making it well-suited for part identification, tooling marks, and traceability applications in manufacturing, fabrication, and industrial maintenance environments. Constructed from hardened steel, it delivers consistent, clean impressions strike after strike. This is a single-character stamp sold individually, designed for use with a standard hammer or pneumatic impact tool.
This stamp is used in industrial and trade settings where permanent character marking is required. Typical applications include stamping part numbers, serial numbers, and inspection marks on metal components, castings, and finished assemblies. It is commonly used by machinists, fabricators, tool-and-die workers, and maintenance technicians who need a durable, reliable individual letter stamp.
Designed as an individual replacement character stamp compatible with standard 1/4-inch steel stamp sets used in industrial marking and identification applications.
Steel stamps are installed by hand or with a stamp holder fixture to ensure straight, consistent impressions. Always secure the workpiece before striking to prevent movement. Use appropriate personal protective equipment, including safety glasses, when operating impact stamps. For best results, strike firmly and squarely with a ball-peen or machinist hammer to achieve full character depth in a single blow.
