Product description
Fischer FH II 10/25 H – heavy-duty sleeve anchor with cap nut 50 pieces
Fischer FH II 10/25 H is a steel heavy-duty sleeve anchor designed for secure fixings in concrete. The H version is equipped with a cap nut, providing a protected and aesthetically finished connection after installation.
Variant 503140 is intended for through installation. It requires a 10 mm drill bit, the minimum drill-hole depth is 80 mm and the maximum fixture thickness is 25 mm. The pack contains 50 pieces.
What is Fischer FH II 10/25 H used for?
The FH II-H anchor is designed for fixing structural components and equipment in cracked and non-cracked concrete. Fischer indicates the FH II-H series for applications including railings, brackets, steel structures, ladders, cable trays, machines, gates, façades and grilles.
The anchor is covered by a European Technical Assessment for use in concrete classes C20/25 to C50/60, both cracked and non-cracked. The manufacturer also indicates possible use in C12/15 concrete and natural stone with a dense structure, provided the fixing is properly selected for the specific substrate and load.
How does the FH II sleeve anchor work?
Fischer FH II is an expansion anchor designed for through installation. After placing the anchor in the drilled hole and tightening it to the required torque, the cone is drawn into the expansion sleeve. The sleeve presses against the wall of the drill hole, creating a mechanical anchorage in the concrete.
The black plastic ring helps prevent the anchor from rotating during tightening and acts as a movement compensation zone. This helps pull the fixture firmly against the substrate.

Selecting the correct FH II variant
The designation 10/25 identifies this specific FH II-H variant: the drill diameter is 10 mm and the maximum fixture thickness is 25 mm. The letter H indicates the version with a cap nut. Other sizes and head types are available in the FH II family, so the correct variant should be selected according to fixture thickness, substrate and expected loads.
Note: the current Fischer variant table for article 503140 does not show seismic approval C1/C2. Therefore, this specific FH II 10/25 H variant should not be described as having confirmed C1/C2 seismic approval.
