C.h. Hanson 25661 Reverse Number Stamp Set 9 Pc

Product Description

The C.H. HANSON 25661 is a 9-piece reverse number stamp set designed for marking metal, plastic, and other hard surfaces where a raised impression is required in the finished workpiece. Each stamp produces a mirror-image number so that the resulting mark reads correctly when transferred or pressed into a mold or die. The set covers digits 0 through 9 and is built from steel for durability under repeated hammer strikes. Characters measure 3/8 inch in height, and each stamp body measures 3-1/8 inches in length with a 5/8-inch shank. The full set weighs 3.23 pounds and ships in a plastic storage container.

Reverse stamp sets are used in tooling, mold making, foundry work, and metal fabrication where a conventional forward stamp would produce a backwards character in the finished cast or forged part. Machinists, tool-and-die makers, and metal fabricators reach for this set when marking cavity molds, date codes on dies, or identification numbers on parts that will be pressed or stamped. The plastic case keeps all nine pieces organized at the bench or in a field kit.

Key Features

• Reverse (mirror-image) character orientation for correct impression transfer into molds and dies
• 3/8 inch character height for clearly legible markings on finished parts
• Steel construction withstands repeated hammer impact without deforming stamp face
• 5/8 inch shank diameter provides a stable grip and positive seating in a holder or by hand
• 3-1/8 inch overall length gives adequate hand clearance during striking
• 9-piece set covers all digits 0 through 9 in a plastic storage container

Compatibility

Designed as an OEM-style replacement and standard-fitment reverse stamp set suitable for use with 5/8 inch stamp holders and typical bench-strike workflows in metal fabrication and tooling applications.

Installation Notes

Reverse stamp sets are installed by hand or in a compatible stamp holder and struck with a ball-peen or hammer appropriate for the workpiece material. Secure the workpiece firmly before striking to prevent movement and ensure a clean impression. Inspect stamp faces periodically for mushrooming on the strike end and dress with a file if needed before continued use. Always wear appropriate eye protection when using hand stamps.
