C.E. Smith 9/16-18 x 3-1/2 Shackle Bolts [11031A]

Shackle Bolts & Lock Nuts, 3-1/2'. Ideal for use with heavy - duty 9/16' eye springs and spring hanger brackets. The fluted shank stops the bolt from turning in the bracket, reducing bracket wear. Sold in pairs.

To use these shackle bolts, first pair them up. They work great with heavy - duty 9/16' eye springs and spring hanger brackets. Just fit them into place. Make sure they're properly tightened. When it comes to maintenance, regularly check for any signs of wear. If you notice the fluted shank getting too worn, it might be time to replace them. Keep them clean to prevent rust and ensure they keep working well. Remember, they're sold in pairs, so always use both for best results.
