Stainless Steel Spinners

Force is lb / in2 so add up the surface rea of the five lug nuts where they contact the wheel then do the same for the spinner. I bet the surface areas are pretty close if not the spinner id more. Soooo if we have more surface area you need less force for the same clamping force. 80lb on the spinner is adequate.

Think about it, you daily driver has Qty 5 lug nuts, each with 90 ft-lb. This is a single nut - ONE. What is really the kicker is the clamping force a bolt/nut combination produces DECREASES linearly as the 'bolt' diameter gets larger. So a single 1/2 inch lug nut at 90 ft-lb produces way, way more clamping force than a knock-off at 90 ft-lb. From there don't forget most cars have 5 lug nuts. The point of the lug nut or knock off is to hold the wheel to the hub. Do you really want to hold you Cobra wheels on with less force than a single lug nut from you daily driver?

Tap-rotate, tap-rotate, tap-rotate. Sometimes it looks like nothing is happening but in minute or two, they start to loosen.
