5/8" 3-1/4 ton Bolt, Nut, & Cotter Carbon Anchor Shackle

Of all shackle types, Bolt, Nut and Cotter Shackles provide the most secure pin 
arrangement, resisting axial and torsional loading. This type of shackle should 
be used in semi-permanent applications where the pin is removed infrequently or 
where cyclical loading occurs. This is the preferred type of shackle in areas that 
are difficult to reach or inspect. Recommended for overhead lifting, bolt, nut and 
cotter shackles are available in capacities up to 50 tons.
