Are the quill stem bolt and wedge steel, or aluminum on this example?

How about the bar wedge and accompanying bolt?

(I inquire as a recently acquired rider came equipped with a 1R stem featuring a (seized and now drilled out) aluminum stem bolt. The conical wedge is aluminum too, as are the bar wedge and its bolt. The threading for the aluminum stem bolt seems to be "Fine" as opposed to not, as it does not match up with other Cinelli steel stem bolts, and they don't thread into the aluminum conical expander. I only have the one 1R so don't know if the steel version of the stem bolt is finely, like 26tpi, threaded or not. So I seek some data, if you don't mind, please?
Also, you might want to specify in your posting whether those bolts are steel or aluminum, and perhaps the weight of the 1R?)

Quill expander and bolt are aluminum. They are 8mm diameter, 1mm pitch.

You know, maybe this quill expander bolt is an OMAS. It doesn't say anything, but its size and shape and pitch and hex are consistent with what I have seen for OMAS bolts.

The bar clamper thingy is aluminum or some type of pot metal. The wedge and bolt are some flavor of stainless: very slightly magnetic. They are 7mm diameter. The threads are very fine - 0.75mm pitch. This is consistent with good practices for stainless, as coarse threads have more of a tendency to gall.

Maybe the aluminum bar clamp wedge bolt you had was also an OMAS replacement. Interestingly, the hexes on both bolts of this stem are 6mm. This is thoughtful of Cinelli. you don't have to carry a weird or large size allen wrench. The weight is 287g. Remember it's a 130mm so it's gonna be heavy. More than the 1A with Arnold Industries or OMAS bolts, but less than the stock 1A.

I have a set of Arnold Industries bolts for the 1A and they are also fine threaded, I believe. I've seen fine threads on the steel wedge and clamp bolt on some 3ttt stems. And with the Whitworth and British Association threads on my Taylor and the SI threads on my French stuff, I guess nothing surprises me anymore.
