Speaker 1: Today, we're gonna take a look at the replacement zinc plated 1/2" diameter U-bolt with the nuts for 2 3/8" round trailer axles. Now this replacement U-bolt will act as part of your trailer suspension system. It's designed to be used with another U-bolt and a U-bolt plate, which we do sell separately, to secure one side of your axle to a leaf spring, which is mounted to your trailer's frame. This round bolt will fit 2 3/8" round trailer axles. It is a zinc plated steel construction. It's heavy duty and corrosion resistant.

It's ideal for use on boat or snowmobile trailers. The part includes everything shown here. The one U-bolt, the two nuts are included. The specs again, the applicant is for 2 3/8" diameter round axles. The inner width here, that's your 2 3/8".

That's where it'll go over your axle. The total length, which would be measured from the inside here to the very end, will be right at 5 1/2" long. Now the thread portion is 2 1/2" long. The bolt size is a 1/2" diameter and the nut size that goes on this is a 1/2" by 20 threads per inch.That would just go on to attach it and this uses a socket or a head size of 3/4". But that should do it for the review on the replacement zinc plated 1/2" diameter U bolt with nuts for 2 3/8" round trailer axles..
