C.h. Hanson 21201AT at Sign Steel Hand Stamp

Product Description

The C.H. HANSON 21201AT is a machine-made individual steel hand stamp designed to strike the at sign (@) character onto metal, wood, plastic, and other hard surfaces. Built from hardened steel, this stamp produces clean, consistent impressions with each strike. The character face measures 0.5 inches (12.7 mm), making it well-suited for marking parts, tooling, dies, and fabricated components where a legible mid-size character is required. The overall stamp body measures 3.75 inches in length, providing a solid grip surface for use with a hammer or mallet. It is sold individually, allowing technicians and machinists to replace or expand a set one character at a time.

This stamp is used in fabrication shops, machine shops, maintenance facilities, and light industrial environments. It is well-matched for part identification, serial number marking, fixture labeling, and traceability applications on ferrous and non-ferrous metals. The 0.5-inch character size is a common choice for structural steel, pipe, and plate marking where marks need to remain readable after coating or surface treatment.

Installation Notes

Steel hand stamps are used by machinists, fabricators, and maintenance technicians. Place the stamp character-face-down on the workpiece surface, hold the shank firmly, and strike the top face squarely with a ball-peen or cross-peen hammer. Ensure the workpiece is secured before striking to prevent movement and misalignment. Inspect the stamp tip periodically for chipping or deformation, and retire the stamp if the character face shows damage that would compromise impression quality.
