Which Nut Rivet Tool for OEM Mudflaps?

Recommended Posts

Hi All,


I'm looking to install the OEM mudflaps on my 2015 Sierra. Looking for some input about which tool to purchase. I've basically got 2 options:


This tool from Ebay for $29.99:



Of course I would order the Metric version


Or this tool from Amazon: http://www.amazon.com/dp/B004KLVJAA/ref=wl_it_dp_o_pd_nS_ttl?_encoding=UTF8&colid=37GY8NV8QZYTA&coliid=I3A2BUXRF5LZLD#productDetails


I'm leaning towards the Amazon tool but am concerned it won't be able to handle the rivnuts that come supplied with the mudflaps. The OEM rivnuts appear to be zinc or the like versus aluminum.


Any thoughts / advice would be most apprciated :)


Thanks in advance!

I tried using the factory zinc nutserts and couldn't get them to work at all.


Borrowed a rivet tool from a friend and used the aluminum inserts that came with the tool. Still holding on tight still and I only installed one in the front instead of the 2 they recommend. I'll take them off this spring and do the second one and probably put some inserts in the rear flap as well.


This is the tool I used:



They aren't really rivets per se.

I ordered the GM factory nut insert tool and all went well. Not sure if electrolysis would be an issue with the aluminum insert to steel; I also utilized the recommended grease to hopefully avoid any corrosion issues.

I, also, got the OEM mud flaps with the large riv-nuts. After drilling for the 1st, scrapped the riv-nut thing and used stainless steel sheet metal screws with countersunk stainless washers. IMHO, those screws and riv-nuts are total overkill for the mudflaps. I was thereafter, done in about 15 minutes.

you can also just use a 6x1.o mm bolt and a same thread nut and some spacer .....it will do the same job and cost about nothing
