1. Oversize Pins: Traditional chain pins are 3mm in diameter. The Key Chain’s are 5mm, and they are available with a hollow or solid pin assembly. These oversized pins are 4-times stronger than traditional pins, and the chances of bending one, whether the pin is hollow or solid, are essentially zero. The 5mm riveted pins provide added strength, but they also provide a bigger contact surface with the chain’s plates, which makes them harder to push out or bend. The hollow pin assembly, by design, allows for a stronger rivet connection to form during manufacturing, resulting in a stronger chain overall.
2. Thicker, Lower Profile Side Plates: Each plate has a low profile and an extra narrow waist that makes it harder to catch the plates at unwanted times. At 1.4mm, the plates are substantially thicker than the plates of any other chain, and they’re also more than 50% harder to [...]
