*** Safety factor=2:1. Pins with grip lengths over 200mm (special) are not heat treated, in order to maintain straightness. Double shear strength will be reduced approximately 20-50%. Steel pins over 200mm long will may have a black oxide finish instead of plating. Pins in larger diameters than listed here are available as specials (may be made from alternate steels).
