Top Features

With full thread and countersunk head.
Made of A2 stainless steel: particularly suitable in external areas and for wet rooms.
High safety due to ETA approval.
Faster bite due to unique PowerFast thread. This extends up to the screw tip.

Premium chipboard screw made of A2 stainless steel with countersunk head and full thread for assemblies in outdoor areas.

Advantages

The unique PowerFast thread reaches into the screw tip and ensures a fast bite. This makes your work noticeably easier with all wood materials.
The shank ribs (for screws with partial thread from 50 mm in length and up) substantially reduce drive-in resistance and thus enable greater power and battery conservation in your work.
The optimised head geometry enables an exact and splinter-free surface finish without the screw twisting off, even with connections close to the edge.
The underhead milled ribbing ensures an attractive surface finish.
The high-performance easy-glide coating reduces friction and accelerates the screwing process.

The fischer PowerFast FPF-ST A2F made of A2 stainless steel is a screw with a full thread and star recess. The countersunk head allows for surface flush installation in wood. The version with a partial thread enables the timber elements to be fastened together tightly. The screw is suitable for fixing load-bearing components in coated wood, hardwood, softwood, and timber connections. These include, for example, all timber connections in external areas, pergolas, fences, façades, play equipment, as well as door and metal fittings.
