C.h. Hanson 21500 Steel Number Stamp Set 1/2 in 9 Pc

Product Description

The C.H. HANSON 21500 is a 9-piece heavy-duty steel number stamp set designed for permanent marking on metal, wood, and other hard materials. Each stamp produces a 1/2 inch character impression and features a 3/4 inch shank for solid grip in a hammer or press setup. The stamps measure 3-3/4 inches in length, giving technicians and tradespeople adequate clearance during use. This set is built for shop floors, fabrication environments, and field marking tasks where clear, durable identification is required. A licensed tradesperson, machinist, or maintenance technician typically keeps a set like this in regular rotation.

The 21500 stamp set is suited for metal fabrication shops, HVAC equipment tagging, plumbing system component identification, electrical panel labeling on conduit or enclosures, and general industrial marking applications. The heavy-duty construction handles repeated impact without mushrooming or deforming the shank. Stamps are stored in an included plastic container that keeps the set organized and protects the striking faces between uses.

Key Features

Compatibility

Designed as a general-purpose heavy-duty number stamp set compatible with standard manual hammer striking and bench press marking applications across metalworking, HVAC, plumbing, and electrical trades.

Installation Notes

Secure the workpiece firmly before striking to prevent movement and ensure a clean impression. Use a ball-peen or cross-peen hammer appropriate to the material hardness. Wear safety glasses during all stamping operations. Inspect stamp faces periodically for wear or chipping and replace individual stamps as needed to maintain legible marks.
