Question:
I have Sumec SR004B 14 x 5 rv aluminum rims that I am putting on my boat trailer but not sure which lugs to use. I was going to purchase solid stainless steel 1/2 x 20 with 60 degree cone. Will these work or do I need something different. The trailer is a for Bass tracker 18 dlx pontoon boat if that means anything.

Hey Steve,
I wasn't able to find any info on wheels using the SR004B part number but it does look like these are conical so the # 12CLN you referenced would work if your wheel studs are 1/2'-20. If they're 9/16"-18 then you'll need the # TA76QR instead.
I'd love to add a picture of your boat and trailer to the page after you get your wheels installed if you'd like to email me a few?
