C.h. Hanson 26141 Low Stress Number Stamp Set 1/4 Inch 9 Pc

Product Description

The C.H. HANSON 26141 is a 9-piece low stress round face full number stamp set designed for marking metal parts, tooling, and fabricated components without inducing stress fractures or surface cracking. Each stamp features a 1/4 inch character size and a 1/2 inch shank, making them compatible with standard stamp holders and suitable for use on hardened and semi-hardened steel surfaces. At 3 inches in length, the stamps provide solid control during impact. The set is stored in a plastic container for organized storage and retrieval. Machinists, fabricators, tool and die makers, and maintenance technicians working in industrial and manufacturing environments rely on this style of stamp for part identification and traceability work.

Low stress stamps are specified when standard V-groove stamps would create stress risers in critical components such as shafts, bearing races, molds, and aerospace or medical parts. The round face full design distributes impact force evenly, reducing the risk of micro-cracking on finished or heat-treated steel surfaces. This set covers the full numeric sequence, making it suitable for serial number stamping, date coding, and part marking applications across job shop, production floor, and MRO environments. The plastic storage case keeps the set intact between uses and prevents tip damage during handling.

Installation Notes

Number stamps are used by machinists, fabricators, and tool and die technicians. Secure the workpiece firmly before stamping to ensure clean, consistent impressions. Use a ball-peen or dead-blow hammer appropriate for the stamp shank size. Inspect stamp tips before each use and avoid striking stamps at an angle, which can damage the character face or cause uneven marks.
