sun visor bracket screws - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Tom Vogel** · 01-27-2009, 02:18 AM

Near as I can tell, the machine screws that should be used to mount the sun visors to the inside of the windshied frame are 5/16 18 X 3/4" long. That size taper head screw wont seat all the way in the countersunk hole in the bracket. A 1/4 20 will seat in the bracket, but it of course is the wrong size to seat in the winshield frame nut.
Wha am I missing here?

1/4-28? Didn't put a tap on it, but could check...anti-sieze and studs worked for my hardtop mount

I'm new to the boards but I do know that some have different tappers on the countersink of the head have you tried a different angle on the countersink?

A member on here a few years ago turned replacment screws out of stainless steel. I can't find the post and I don't remember the username, just that the member had their own website and was repairing some serious bedside accident damage on a nice red Blazer.

Good news: I found the board member who made these and the post where they were for sale: http://67-72chevytrucks.com/vboard/s...ad.php?t=83233

Bad news: this member hasn't been active in over a year and their website doesn't work anymore
