Fischer Hammerscrew 8 x 100mm (Pack of 50)

FISCHER 50357 N8 X 100Z HAMMERFIX is a zinc-plated nail push-through fixing designed for a variety of applications. The fixing expands when the nail is hammered in, providing a secure hold through friction in the drill hole. It is suitable for concrete, natural stone with dense structures, solid brick, solid sand-lime brick, solid blocks made from lightweight concrete, aircrete, gypsum panels, vertical perforated brick, perforated sand-lime brick, hollow blocks made from lightweight concrete, and other common wall substrates. The system employs a countersunk screw head for a neat finish and a cross-slot recess that allows the thread of the nail screw to be removed for potential dismantling. An integrated hammer-in stop prevents premature expansion (jamming), enabling smooth installation and reliable performance in timber substructures, wall and plaster profiles, and related fastenings.
