come and create a waterproofing on an IPN to screw a cross joist for 4x30 stainless steel wood screws on IPN steel
Allows us to ensure the sealing of steel trays, formed by a folded cassette with two returns and a bottom sheet. The bottom sheet is fixed by screws entering threaded inserts placed on the cassette. An EPDM seal goes all the way around the contact points between the sheet and the cassette, but the M4 screws are on the side of this seal. Hence the use of rubber washers. The screws are M4x16, in order to take into account all thicknesses (rubber washer, bottom sheet, EPDM seal, head of the insert, sheet of the cassette and part of the insert passing from the latter D)
