Stainless steel bumper bolts for front wings

[redmonty]

I have been bugged for many years by the old rusty chrome front wing bolts on my 1985 Marlin LWB roadster. Why I have never changed them I never know, so now before I start doing major mechanical work to get it back on the road, I thought I would do a nice easy cosmetic job to replace the front wing bolts with something that will never rust again (the area around the bolt head has sunk in slightly into the wings now, making a nice water trap to encourage more rust). I have been looking at various listings on Ebay and none of them give the thread diameter, square size under the head or the domed head diameter!

These are the dimensions of the existing chrome bumper bolts I have:
The threaded bolt diameter is just over 6mm (probably 1/4"), the square bit at the top is fractionally over 6mm wide and the head is 14mm and their length is about 3/4" in total including top of head. So are these bolts Escort M1/MK2? If they are fractionally longer that isn't a problem, but the bolt threaded diameter and square bit at the top is important.

Has anyone else used polished stainless bumper bolts from ebay?

Take a look at Westfield Fasteners website under the coach bolt section - you'll find all the relevant information you're after for the various bolt sizes. Just replaced those on son's Roadster with 8mm stainless button heads. And good luck getting the nuts undone as there is nothing to prevent the bolt spinning so in all likely hood you'll need to cut nuts with a dremel or similar.

Thanks for the info... I looked and found something that was a close match, but they don't seem to be highly polished. What was the finish like?

Button heads finish I considered good , but maybe more of a satin than what you would get with Chrome.

Thanks for letting me know. I think I'll get some and then polish them to see if I can get them to look like they are chromed. Cheers!
