JIS (Japanese Industrial Standard)

• Core pin diameters: 1.0-20.0mm
• Head style: 90 degree countersunk or flat
• Tolerance: m6 (shank)
• Common in: Japanese and Asian mold shops

DIN/ISO 6751 (European Standard)

• Core pin diameters: 1.0-25.0mm
• Head style: Flat with 15 degree chamfer
• Tolerance: f7 or m6
• Common in: European mold builders

HASCO (German Standard)

• Core pin diameters: 1.0-32.0mm
• Lengths: 100-630mm
• Material: HSS, nitrided 1.2343, or through-hardened
• Common in: European and growing Asian markets

DME (North American Standard)

• Core pin diameters: 1/32 to 1 inch (imperial)
• Material: H-13, M-2 HSS

Practical tip: If you export molds, specify pin standards upfront. A mold built to HASCO standards is serviceable in Europe immediately. A DME mold requires DME-stocked spares.

Cross-reference charts are available from most pin suppliers.
