C.h. Hanson 21400 Heavy-duty Number Stamp Set 9 Piece

Product Description

The C.H. HANSON 21400 is a heavy-duty steel number stamp set designed for permanently marking metal, wood, plastic, and other hard surfaces. The set includes 9 individual number stamps, each with a 3/16 inch character size suited for legible, precise impressions on parts, tooling, and equipment. Each stamp measures 2.75 inches in length with a 3/8 inch shank, making them compatible with standard hammer striking. The stamps are stored in a plastic case for organized access on the job site or in the shop. Licensed tradespeople and industrial maintenance technicians rely on this set for part identification, date coding, and traceability marking.

This stamp set is used across a range of trade and industrial applications including HVAC equipment tagging, plumbing pipe identification, electrical panel labeling on metal surfaces, and general metal fabrication. The heavy-duty construction handles repeated hammer strikes without deforming, making it a practical choice for both shop use and field service work where permanent marking is required.

Installation Notes

Number stamps are driven by a hammer or mallet onto the target surface. Secure the workpiece firmly before striking to ensure clean, consistent impressions. Use appropriate personal protective equipment including eye protection when operating hand stamps. Stamps should not be used on hardened steel surfaces harder than the stamp material, as this may damage the character faces.
