I am wondering what type of screws people use for their rear magnesium wheels for high HP drag cars? I already know a lot of people don't use them but my wheels were already drilled prior to my ownership so I am planning on using them. I've heard different metals can have a reaction with magnesium causing the magnesium to corrode. Stainless?
Yeah, I saw that thread already. I didn't really see any recommendations in it though for the specific type of screws to use and/or discussion on the best type of material for them that won't cause corrosion to the magnesium.
Do you actually need the bead bolted? Or are you just wanting to fill the hole? Magnesium bolts Aluminum bolts They even make plastic bolts If it’s just for looks and to fill the hole ho with one of these in the shortest length possible ( ie: just ad thick as the bead) If your actually needing them to hold the bead in place a cad coated bead lock bolt with anti-seaize? And stainless corrodeds magnesium but I guess if you remove them frequently and clean them and recote with some grease etc. Would be ok. Seems messy and time consuming to me
Here's some helpful info. about fasteners that don't react with magnesium. https://www.arboristsite.com/commun...asteners-do-they-react-with-magnesium.122317/ and also browse here: https://www.google.com/search?q=bes...69i57j69i60.6163j0j4&sourceid=chrome&ie=UTF-8 Coating the fastener with sealer(Permatex) will also prevent corrosion
The grade 8 hex head screws that Moroso sells, use a touch of oil before inserting them and just tighten till the base touches the rim and no more
I agree on the moroso screws. They are far better than any hardware store screws. Dont cut corners you will be sorry. You are screwing into a steel braded bead. The aluminum and stainless screws are too soft. The wheels will corrode regardless of what is used. Moisture is the wheels biggest enemy. Make sure the holes are the correct size. If they are too small the screws will shear. You want them to bite into the rim just a little bit. It helps pull the screws in. I always inflate the tires ten pounds over before i put them in. If the holes are too big pre drill the tire. Tape the bit to create a stop so you don't go too far. If a hand held ratchet doesnt allow the screw to bite i then use my 3/8 battery powered impact. It turns faster. So you get the description correct rim screws are not bead locks. A bead lock rim is something completely different. It uses bolts.
Me? Since the wheels are already drilled, I would goop glue in some too short, too thin screws on the outside just for cosmetic/ol' school reasons. If you toss one at the track or at a show, a 1/4" screw won't ruin anyone's day. Then get a bumper sticker that says "Save the Whales, Save the Mags"
what is old school about faking wheel screws? back then the cars were real and the screws served a purpose. YOU SAY IF YOU TOSS ONE AT THE TRACK ITS NO BIG DEAL. ARE YOU F IN KIDDING ME? the next car down the track could get a punctured tire and crash. today is a first for me after a lot of posts on the hamb when I reply saying that was a very stupid comment. congrats.
If you are going to fill the holes, do it right, another vote for the Moroso fasteners. They were chosen to fill this task "properly". Otherwise...there's no shame in leaving the holes "unfilled". As another poster mentioned, you don't want fake screws coming out for someone else to run over. Mike
