I was wondering about the strength difference of Trailer Axle Spring Shackle Grease Type Eye wet Bolt 9/16 x3 vs regular shackle bolt 9/16 3, if any. Thank you.

Expert Reply:

A wet shackle bolt like the Redline # 126B2, the type that is hollow with a grease zerk fitting for lubrication, is just as strong as the dry (solid) type like # 166081. Neither variety of this part actually carries a weight capacity rating since the trailer weight is distributed across many of them.
