C.h. Hanson 21151O Steel Letter O Stamp 3/8 Inch

Product Description

The C.H. HANSON 21151O is an individual machine-made steel stamp used to mark the letter O onto metal, wood, plastic, and other hard surfaces. It is designed for permanent character impressions in fabrication, tooling, and parts-identification applications. The stamp features a 3/8-inch character size and a compact body measuring 3.13 inches in length, 0.56 inches in width, and 0.56 inches in height. At 0.26 pounds, it is light enough for single-hand use with a hammer or arbor press. Machinists, fabricators, welders, and maintenance technicians typically keep individual letter stamps on hand for custom marking tasks.

This stamp is suited for use in machine shops, fabrication facilities, maintenance departments, and light manufacturing environments. It performs well in applications that require clear, repeatable character impressions on workpiece surfaces. Individual stamps like this one are commonly used alongside full alphabet sets when a single character needs replacement or when only select letters are required for a specific marking job.

Installation Notes

Place the stamp character-side down on the target surface and strike the head with a ball-peen hammer or position it under an arbor press for uniform depth. Secure the workpiece before stamping to prevent movement and ensure a clean impression. Use appropriate eye protection when striking steel stamps. No special tools or certifications are required for standard hand-stamping operations.
