What Tool For This Screw?

Hey Larry,
NAPA will have the bit for your screw drivers for those screws. I forgot what they are called by name but they are kinda shaped like bow ties. I got my two bits for them at NAPA but I'm sure other tool places might have them. They were kind of hard to find though. Lowes, Autozone, Advance, Fastenall, Farm & Fleet all didn't have them. Get one out with a smaller common slot screwdriver and take it with you on your trip to NAPA. I think 2 or 3 bits were less than $7.00 there.

I always seem to got those bits in the Christmas cheapo tool kits. Always were handy in the old mobile home I used to live in as there were screws with this head all over. Maybe Harbor Freight worth a look too.

Yup just found em on Napa online www.napaonline.com/Catalog/CatalogItemDetail.aspx/Insert-Bits-Clutch-3-16-x-1-/_/R-BK_7755921_0006392984

Sorry Larry.
I don't know about the gasket. (we are supposed to be learning from your mistakes so we don't have to make them ourselves!)
I do know that the pic above that gonekayaking posted from NAPA is a Phillips bit. NAPA website has the wrong pic posted!
See pic of bit and diagram of shape of tip;

Just because your retired now doesn't mean you can stop making our videos!

Window assembly needs to be removed, then you will be able to see what your working on better. Make sure you pry off the two inside covers that go between the center and the small outer windows to gain access to the center screws/nuts. Make sure you replace the screens while you have it all apart. The only screen material you want to use is actual galvanized steel screen (or maybe copper or bronze if your bucks up, LOL). Fiberglass and aluminum screen will not work on the early windows. You can buy steel screen from VTS, or McMaster Carr.

An actual clutch head screw driver will be shaped just like the hole in the screw head and like Phillips heads they come in different sizes. Three sizes if I remember right. They were a production screw very popular in the trailer industry.
