Product description
Fischer PA 4 M6/7.5 sold individually – single brass fixing with M6 thread
If you only need one fixing for a bracket, lamp, furniture fitting or a small repair, this offer allows you to buy 1 piece of Fischer PA 4 M6/7.5 without purchasing the complete box of 200 pieces.
This is a single fixing taken from the original Fischer art. 50484 pack. The individual 1-piece sales unit does not have its own manufacturer EAN.
When is it worth buying PA 4 M6/7.5 individually?
Individual sale is practical for repairs, service work and small installations where only one or a few fixing points are required. It allows you to order exactly the number of fixings you need without purchasing a complete box of 200 pieces.
For series installation or projects requiring a larger number of identical fixing points, a separate product page for the complete original pack is available.
What is Fischer PA 4 M6/7.5 used for?
Fischer PA 4 is a brass expansion fixing with a metric internal thread. Typical applications indicated by the manufacturer include brackets, angle brackets, furniture fittings and lamps.
It can be used in suitable thin building panels, wood-based and plastic panels as well as solid building materials such as concrete, solid brick, solid sand-lime brick and natural stone with a dense structure.
Why is the M6/7.5 version so short?
The M6/7.5 version has a body length of only 7.5 mm. Its short design requires little anchoring depth and can therefore be useful where the amount of material available behind the mounted component is limited.
The fixing has an M6 internal thread and is designed for use with a standard M6 metric screw selected for the particular application.
How does the PA 4 fixing work?
PA 4 is intended for pre-positioned installation. The fixing is first inserted into the prepared hole. The component to be fixed is then positioned and a suitably selected metric screw is installed.
When the screw is tightened, the front section of the brass fixing expands in the substrate and creates a mechanical anchorage. The profiled external surface helps prevent the fixing from rotating inside the hole.
How should the hole be prepared?
For Fischer PA 4 M6/7.5 art. 50484, the nominal drill diameter is 8 mm. The minimum hole depth and fixing length are 7.5 mm.
Installation parameters must always be matched to the actual substrate and the manufacturer's current recommendations.
How to select the M6 screw?
The fixing has an M6 internal thread. The screw length must be selected according to the thickness of the component being fixed and the required screw-in depth.
For flush installation, the manufacturer's principle can be applied: the fixing length plus the thickness of the component being mounted determines the minimum required screw length.

Important when selecting a PA 4 variant
PA 4 is available in different lengths and thread sizes. The M6/7.5 version is particularly short and should not automatically be replaced with a longer fixing simply because it has the same M6 thread.
Before ordering, check the required fixing length, the available space in the substrate and the required screw diameter.
