The Types PF7M and PF7MF captive panel screws offer two distinct mounting styles for permanent installation into thin sheets. Both types feature small, compact, and low-profile designs employing patented MAThread anti-cross threading technology that corrects off-angle installations, aligns components, and slides through clogged internal threads. Their Phillips recess allows for tool or hand operation. Type PF7M captive panel screws integrate a self-clinching mounting design providing high pushout resistance while the Type PF7MF captive panel screws feature a flaring design, which allows them to be installed permanently into any panel hardness with minimal force. Both types feature a shoulder on the retainer portion of the fastener to help simplify installation. PENNENGINEERING, Danboro, PA. (800) 237-4736.
