For roofing applications, the SPIKE® is a one-piece, vibration resistant anchor available in 3/16" and 1/4" diameters for use in fastening insulation, single-ply membrane, wood, and metal to structural concrete roof decks. This version of the SPIKE® has a Perma-Seal™ coating a proprietary fluoropolymer which meets the corrosion resistance requirements of FMRC Standard 4470. It is designed for use in conjunction with Powers insulation or membrane stress plates.

The Powerlite™ is a fastener used to mechanically attach rigid insulation board and single-ply membrane to structural cement wood fiber, gypsum, and lightweight insulating concrete roof decks. The fastener is used in conjunction with insulation and membrane stress plates. The plates are manufactured with four barbs on the underside that grip the insulation board or single-ply membrane preventing rotation.

Stress Plates are designed for use with Deck Screws and Spike anchors. For Powerlite specially designed stress plates are listed in the applicable product sections. Stress plates are used when attaching insulation and single ply materials to distribute load and prevent the material being fastened from pulling over the head of the fastener. In addition to the stress plates, a sealing washer and a plastic bearing washer are available for use with flashing and termination systems.

Stainless Steel Sealing and Plastic Washers are typically used with 1/4" diameter anchors for roof flashing, termination bar and dissimilar metal applications.
