This Zinc Plated Leaf spring trailer bolt is used to mount different types of leaf springs on the trailers suspension. This is a 1/2 inch x 3 1/2 Zinc Plated leaf spring bolts that comes with a nylock nut. With boat trailers, 1/2" diameter bolts are much more common. For land trailers, 9/16" diameter bolts are more common. However, their is some cross over depending upon the trailer manufacture, so it is best to confirm your leaf spring bolts diameter before order. Zinc Plated bolts offer corrosion resistance and strength that is crucial in your trailers suspension. To increase the life of your spring bolts, apply corrosion protection spray such as Boeshields T-9 Rust and Corrosion Protection Waterproof Lubrication Spray. This spray will drastically increase the life of all your non stainless steel trailer components. Zinc Plated Bolts can be installed with either an impact gun or hand tools.

Common Single Axle Double Eye Leaf Spring Suspensions will have (3) of these Bolts per side. Tandem Axle versions of the double eye suspension will have (7) of these bolts per side. 
For Reverse Curve Leaf Springs, if they are using 1/2" Bolts, they will have (2) Per side on a single axle suspension, and usually (4) per side on a tandem axle suspension. (Reverse Curve Springs more commonly use 9/16" hardware)

High Quality and Good Price
Replacing my rusty leaf springs and bolts. Found these here for a good price. The zinc plating is nice and will prevent rust for a long time. The quality of these is much better than what you find in the big box hardware stores. Make sure to get the Trailer Leaf Spring Bushing 1/2" ID, 11/16" OD for boat trailers, as recommended. I thought the graphics on the sample photo were pretty cool. unfortunately, the shipped items are plain. no big deal... just thought I'd mention it.
