C.h. Hanson 25521 Reverse Number Stamp Set 9 Pc

Product Description

The C.H. HANSON 25521 is a 9-piece reverse number stamp set designed for marking metal, plastic, and other hard surfaces where a raised or mirror-image impression is required. Each stamp is machined from steel and features a 5/16-inch shank, making them compatible with standard stamp holders and fixtures. The character size is 1/16 inch, suited for fine, precise marking applications. The set comes in a plastic storage container that keeps the stamps organized and protected between uses. Licensed trades and industrial professionals use these stamps for part identification, die work, and metal fabrication.

Reverse stamps produce a mirror-image character impression, which transfers as a readable, forward-facing mark when pressed into soft material or used in casting and forging applications. This set is commonly used in tool-and-die shops, machine shops, and metalworking environments where standard forward stamps would produce a backward result in the final product. The 1/16-inch character size is appropriate for tight-tolerance marking on small parts or in areas where space is limited.

Installation Notes

Stamp sets of this type are used by machinists, tool-and-die makers, and metal fabricators. Secure the workpiece firmly before striking to prevent movement and ensure a clean impression. Use a hammer or mallet appropriate to the workpiece material and stamp size. Inspect stamps for mushrooming or deformation on the strike end before use and dress or replace as needed to prevent injury.
