    Squeeze these pins into holes and they expand slightly, creating tension to hold parts in place. They are often used as hinge pins and as fasteners for springs and power transmission components. An alternative to dowel pins, they're lighter in weight with a hollow center and don’t need a precise hole. Also known as roll pins.
    Breaking strength is measured as double shear, which is the amount of force required to break a pin into three pieces.
    Spring Steel—These pins won't deform from stress and vibration. Although they're stronger than stainless steel, they're best for dry environments since moisture will cause them to rust.
    Zinc-Plated Spring Steel—These pins withstand occasional exposure to moisture. However, since friction from moving parts can wear away the finish, they're not ideal for wet environments. While not nearly as corrosion resistant as stainless steel, they are stronger and won’t deform under stress.
    Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.
    Wear-Resistant 400 Series Stainless Steel—Our most wear-resistant stainless steel pins, these are good for pivoting parts that create a lot of friction. They hold up in environments that experience occasional moisture, but they're not as corrosion resistant as 18-8 and 316 stainless steel.
