Introducing the C.H. Hanson 21628 Heavy Duty Stamp Set — a precision 1/4" letter and number stamping kit built for hand-held, hammer-struck marking in real-world shop conditions. Designed for moderate industrial applications, this set delivers clear, durable characters when you need fast, reliable labeling right on the workpiece.

What makes this set stand out

• 36-character collection — digits 0–9 (with 6 used as 9), A–Z, and an ampersand (&), giving you instant capability for part IDs, serials, batch codes, and naming conventions.
• Crowned striking surface — directs every hammer strike to the center for consistently legible marks, reducing mis-stamps even after repeated use.
• Oversized shank — improves grip and stamping control, helping you align characters quickly and accurately.
• Tempered shanks — engineered for safety and longer tool life in demanding hand-stamped labeling workflows.
• Balanced 1/4" stamping diameter — optimal readability on metal tag, nameplates, and other markable surfaces without overwhelming the work area.
• Versatile for a range of substrates — excels in moderate industrial labeling scenarios, from metal fabrication to inventory tagging and equipment marking.

Practical uses in the shop

• Label machined parts, tool chests, and inventory with clear, transferable codes.
• Apply batch or date identifiers to fixtures and electrical panels for easy traceability.
• Create personal initials or department identifiers on leather, wood, or metal tags used in workshop workflows.
• Maintain consistent branding across labels and tags by using the full alphabet and numbers in a single kit.

Why this kit fits your workflow

• Designed for durability and repeatable results, so you can stamp confidently during routine labeling tasks without swapping to a different tool.
• All characters you need in one compact set, eliminating the need to mix and match with separate stamps.
• Ideal for shops, makerspaces, fabrication facilities, and maintenance teams that require fast, legible identification on a variety of surfaces.

Tips for best results

• Clean the stamping surface to ensure sharp, clear impressions; debris can dull marks.
• Center the stamp on the mark area and maintain a steady, controlled hammer strike for consistency.
• Test on a scrap piece before applying to the final workpiece to confirm depth and legibility.
• Store the set in a secure holder to preserve character integrity and prevent misalignment between uses.
