Brass fixing PA 4

The brass fixing for thin board building materials and solid building materials

The fischer brass fixing PA 4 PA 4 is a special plug for fixing metric screws in thin panel building materials. The special fixing is ideal for fixing handles, angle brackets or lamps in wooden board building materials, plastic boards, but also in concrete, solid brick and sand-lime solid brick. The brass fixing is set in a pre-positioned installation. When screwing in the screw, the plug expands and anchors itself in the building material. The special surface structure of the PA 4 prevents the fixing from rotating in the drill hole. This increases installation safety.

Product Description

  • The short brass fixing PA 4 only requires a very low anchorage depth and is therefore the solution for thin board building materials.
  • The special surface structure of the PA 4 prevents the fixing from rotating in the drill hole. This provides increased installation safety.
  • The internal thread allows for the use of standard metric screws and enables the ideal adaptation to suit the intended use.
