If you want to use countersunk screws, you can use 100 degree aircraft c'sunk screws and use a stainless countersunk CSK) washer. It will give you the low profile of the CSK screw, and the washer will distribute the load so that the only force on the plexiglass is the clamping force. Both the CSK screws and washers are available from Aircraft Spruce and Specialty Company. 951-372-9555 (California) or 877-477-7823(Georgia) ----- Original Message ----- From: "Norm Lane" <[EMAIL PROTECTED]> To: "'For and about Montgomery Sailboats'" <[email protected]> Sent: Sunday, April 23, 2006 6:37 PM Subject: RE: M_Boats: Replacing M15 windows
