YC607 Combination Steel Stamps
YC607 is a 36-piece letter + number combination set — 27 letters and 9 numbers. Mix letters and numbers freely to stamp serial numbers, lot numbers, dates and model codes — clear, permanent industrial marking and part traceability.
Suitable materials: General metals, stainless steel, aluminum, brass, nameplates, tools and leather.
Core Features
Made of CR-V (6150) chrome-vanadium steel.
The character head reaches HRC 58–62 for lasting, clear marks; the striking end is tempered to HRC 38–46 to absorb impact and prevent cracking.
One set replaces separate letter and number sets — stamp any alphanumeric code, from serial numbers to date codes.
A double-bevel design makes visual alignment and precise striking easy.
Font and size are marked on the side of the stamp for fast identification during work.
The surface is sandblasted for a better anti-slip grip and greater durability.
Slotted PP box · a home for every stamp
A slotted PP box keeps all 36 stamps neatly organized and easy to reach:
Every stamp has its own slot — nothing scatters or gets mixed up, and each returns to its place.
Letters and numbers are arranged in order so you find the character you need fast.
Smooth to take out and put back, for higher working efficiency.
One box holds all 36 letters and numbers, easy to keep and carry.
