Triangle Fastener Corporation (TFC) announces that the company’s ¼-14 DP3 Concealor Pancake Head Screw is now FM approved for wall fastening per FM Approval Standard 4881 — Class 1 Exterior Wall Systems.
TFC developed the ¼-14 DP3 Concealor Pancake Head Screw specifically to attach Insualted Metal Panels (IMPs). According to the company, the screw’s unthreaded section eliminates jacking of the insulated panel during face fastening. The screw has a #3 square recess drive that provides stability during installation, and its large diameter pancake head is designed to increase pullover strength compared to smaller diameter heads. The screws are TRI-SEAL coated for superior corrosion protection.
