254 SMO Fasteners
254 SMO (1.4547) fasteners are made of a high-end stainless steel alloy that was developed for resistance to saltwater and chloride corrosion. This 6-Moly (6% Molybdenum) alloy has good localized corrosion resistance and 254 SMO provides much higher strength than other austenitic stainless steels. 254 SMO bolts are an ideal choice for high chloride environments including brackish water, seawater and other applications that demand heavy use of chlorines and chlorides. Compared to sister 6-Moly alloy AL6XN, 254 SMO fasteners offer slightly less high temperature stability corrosion resistance and strength.

254 SMO Screws
12 Point Screws254 SMO 12 point screws are ideal when you need higher torque than socket head cap screws offer. These screws are available in 1/4" diameter or larger. The only drawback is 12 point screws are less economical and require a higher minimum quantity due to the complexity of production.• IFI-115
