BK Double Pins give accurate, repeatable die placement in sectioned models. Each die needs only one drill hole; the tapered pin fits narrow dies, a short friction zone lets the die lift out easily and reseat firmly, and the asymmetric pin cannot be put back the wrong way round.
Why labs choose it
- One drill hole per die – faster preparation with secure support
- No rocking or rattle
- Works with standard Pindex-style pinning drills and standard 16 mm model bases
- Rubber end caps are packed loose for quicker handling
Two sleeve types
- Plastic sleeves – corrosion-proof, protect the model base, the everyday choice
- Metal sleeves – added strength and long sleeve life for technicians who prefer metal
Details
- Each box: 1,000 double pins, 1,000 sleeves and 1,000 rubber end caps
