C.h. Hanson 21151AT Steel at Sign Stamp 3/8 Inch

Product Description

The C.H. HANSON 21151AT is a machine-made individual steel stamp used to mark the at sign character onto metal, wood, plastic, and other hard surfaces. The stamp measures 3.13 inches in length with a 0.56-inch by 0.56-inch face and produces a 3/8-inch (9.5 mm) character impression. Constructed from hardened steel, it is built to withstand repeated hammer strikes in production marking, part identification, and quality control applications. This is a single-character stamp intended for use with a hammer and compatible stamp holder or by hand for light marking tasks. Machinists, fabricators, and maintenance technicians are the primary users.

This stamp is suited for metal fabrication shops, machine shops, maintenance and repair operations, and industrial production environments. It is used wherever permanent character marking is required on raw stock, finished parts, tooling, or equipment. The at sign stamp is typically paired with other individual character stamps from the same series to build out a complete alphanumeric set. It works on flat and mildly curved surfaces and is commonly used for traceability stamping and part serialization.
