Top Features

Product Description

The fischer Power-Fast FPF-SZ A2P made of A2 stainless steel is a screw with a partial thread and cross-slot 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. This is the case for car port fixings and when erecting balconies.
  • The unique Power-Fast 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 ETA approval guarantees the high safety and premium quality of fischer Power-Fast screws in soft and hard woods.
