From the maker · Johns Manville’s description

Johns Manville Lite-Deck fasteners and plates fasten insulation in both multi-ply and single ply systems, installing into cementitious wood fiber decks without pre-drilling. Each #3 square-drive steel fastener pairs with a 3 in. round galvalume-coated steel plate, in black fasteners and gray plates. Available boxed in 3 in., 4 in. and 6 in. lengths with 250 or 500 pieces per box by size.

Coverage & How Much You Need

Coverage depends on the fastening pattern specified for your JM roof system; divide the roof area by the required fastener density to determine how many boxes to order per square.

Fit and Compatibility

Designed for insulation fastening in Johns Manville multi-ply and single ply roof systems on gypsum and cementitious wood fiber decks. Select fastener length for insulation thickness plus required penetration into the deck per the JM specification.
