I'm installing some Great Planes mechanical retracts, no screws are supplied to attatch them to the LG rails.

The holes in the mounting flanges on the gear are "countersunk" to accept a screw with the beveled head, so that the top of the screw is flush with the flange when installed. The only #4-1/2" screws with this type of head I've been able to find are Robertsons. Call me picky but I'd like to have everything on the plane serviceable with my set of ball drivers.

Anyone seen socket head screws with this type of head?

No problem, it's a flat head socket cap screw. You may have to go to a specialty screw distributor or mail order. If you live in a medium or larger town, someone probably has them on the shelf.

i just bought some screws similar to what you want for my son's r/c buggy...check your LHS in the car area...they use those for the undercarraige

Thanks guys!

Try microfasteners.com, they have them listed but I did not look to see if they have the size you wanted. I have purchased items from them several times and have gotten very good service.
