Lug Nut Tech Description

[turbo79]

I'm looking to get some replacement lug nuts. I have aftermarket wheels with no hub covers. I now have a set of chromed closed end lug nuts. They rust!

All this to get to the question I need help with: what is the actual thread pitch and stud diameter on Taurus hubs?

There's a company called Skunk2 in Cali that makes a lot of aftermarket performance parts for Hondas and Acuras, and they sell hardened metric aluminum/magnesium lug nuts in sets of 20 for Acuras and Accords. Anyone know where I can look up any comparison data showing if the lug nuts on an Accord are the same spec. as on a Taurus?

Thanks in advance!

i think its M12x1.5 for the taurus

^^^^ this is correct.
If you don't have your heart set on one manufacturer, check RockAuto, they have about 30 different lug nuts you can choose from.

If you are stumped in the future about a thread size, a lot of the box stores have a thread checker in the hardware department and often they have metric as well. For a nut, it is simply a whole series of studs on a display rack that you try to thread on your nut.

12x1.5 with a 60 degree conical seat.

I would not even consider installing aluminum lug nuts on any vehicle that I or any family members drive. Even hardened al has half the strength of steel.

The company - Skunk 2 - makes this claim on their web site:

Product Description
Forged from ultra-strong 7075 aluminum, Skunk2’s Lug Nuts for most Hondas and Acuras, Mitsubishis, Scions, and Toyotas feature knurled ends for maximum grip, hard anodizing for superior corrosion resistance, and an attractive finish. Skunk2’s lightweight Lug Nuts have also been proven on the race track for nearly a decade so you can be assured of both quality and longevity. Weighing in at a lightweight, industry-leading 23.5g, Skunk2 Lug Nuts help reduce unsprung weight but without compromising strength. Each lug nut also features a perfectly tapered end for maximum wheel-to-lug contact as well as durable threads for added longevity.

I do note that aftermarket custom and even racing wheels are often made out of aluminum. Aluminum Cragars date back to early Mustang days.

I'll keep looking up info. on lug nuts and safety, but I definitely want to get away from lug nuts that rust. Saving on unsprung weight would be a positive bonus, as I remember the criticality of that when calculating details on race cars and motorcycles from back when I road raced motorcycles.

7075 aluminum is new to me, so I spoke slightly out of school. The yield strength of heat treated 7075 at 73kpsi is similar to that of grade 2 steel (from which nearly all lug nuts are made) at 74kpsi.

However, the modulus of elasticity of steel is still 3X that of aluminum (which means the aluminum nuts will flex 3 times as much) and the impact resistance appears to be around 50% of the steel nuts.

Not to mention the issue of galvanic corrosion between the steel studs and the aluminum nuts.

So, I stand by my statement that I would never use them.

matches what i learned in my materials class.

the lightweight pro is not enough to offset the other factors.
including a much shorter service live.
