Hanging a heavy object and securing it securely to a hollow surface is not an easy task. It becomes impracticable if the wrong fasteners are used. Soft and porous materials such as brick, aerated concrete and concrete require special fasteners. For this, the Fischer dowel was developed, which in some cases simply cannot be done without.

Working with specific fasteners requires compliance with all installation rules and operating conditions, and the scope of their application is quite extensive - use even at home. The innovative technology has made their installation simple and affordable, providing a super strong connection.

Peculiarities

The Fischer dowel is designed to ensure high mechanical strength and withstand dynamic loads … Manufacturing materials provided it with high resistance to chemical and weathering. The unique solution prevents the formation of condensation on the surface of the dowel, which extends its service life up to several decades.

Fischer universal dowels They are used for the installation of many types of structures, both having a relatively low weight: shelves, wall cabinets, mirrors, and quite large and heavy ones . In addition, some types of universal anchors are used for working with drywall and drywall, while others are suitable for concrete, hollow and solid bricks.

They have an edge that limits the insertion of the dowel into the hole during installation. Experts advise inexperienced builders or amateurs to make repairs with their own hands, who have a very poor understanding of the physical properties of materials.

Types and models

Fischer dowels are parts designed to connect parts of a structure. They are presented in several varieties.

• Dowel for hollow bricks . For fasteners in concrete and concrete slabs with voids, for solid material and wild stone, expansion anchors are used.
• Double-space anchor bolts used in work with solid concrete composition and bricks.
• Chemical anchors for increased loads, they are used for external and internal installation work. They work with all types of concrete.
• Average anchors work in all types of concrete. Frame, front ones are of a spacer type, made of polyamide nylon. Hexagonal screws are made from galvanized and stainless steel.
• Dowel-nails used for mounting objects to materials made of solid bricks, concrete or stone materials. They can be hammered into a dowel or used as an independent fastening element. When working with them, they use a construction and assembly gun. The dowel-nail can be with or without a thread, sometimes it has a centering washer at the end. The nail itself is made of steel and has a zinc coating, the dowel is made of high quality plastic.
• Steel types used in work with heavy hollow materials. May have a ring or hook at the end. Such a dowel can withstand high mechanical stress in materials of small thickness. The sleeve is made of steel or brass, a self-tapping screw, nail or hot-dip galvanized steel screw is inserted inside. Fasteners for thermal insulation are a dowel with a plastic, steel, fiberglass nail, with an impact-resistant head. There are disc types for roofing. Frame anchor dowels are used for mounting doors and windows.

Model range of Fischer dowels

Universal dowel Fischer DUOPOWER suitable for installation with all types of materials. It has a large functionality - knot tying and a spreader allows you to use it in an array of undefined type. The sleeve of such a dowel makes a spacer in solid materials, and when working with hollow materials, they are tied into a knot.

DUOPOWER S - its functionality is similar to the first one.

Fischer DUOTEC originally designed for heavy construction, building panels. It has two types of fasteners: a dowel and a sleeve with a hole for a screw to enter. The fasteners are interconnected with a special ribbed tape, which makes the fastener elastic and allows you to change the distance between the main elements. The product is made of combined plastic, reinforced with fiberglass during the manufacturing process. Fiberglass does not affect the flexibility of the dowel, but it increases its strength.

Dowel for aerated concrete Fischer GB nylon - fasteners for installation in aerated concrete material. The device has a spiral shape, it is quite easy to assemble with a hammer. Its undemandingness to special tools gives a good saving of time for the installation of fasteners. If using stainless steel screws, the dowels can be used for outdoor use. Due to the spiral ribs, the dowel evenly distributes the pressure and guarantees reliable adhesion to the material. A large selection is offered - up to 280 mm. The product is classified as a preliminary installation type.

Dowel without edge Fischer UX is a versatile tool. It is used in all kinds of materials, has locking teeth and notches. Equipped with eye bolts, hooks and rings, bolts.

Product Fischer UX GREEN defined as an environmentally friendly dowel. Has a universal purpose, angular notches, works in any materials.

Scope of use

Fischer products are widely used in the construction industry, during minor repairs. The materials for which this fastener is suitable are quite diverse:

• concrete;
• concrete slabs with voids inside and for steps;
• lightweight concrete;
• hollow and solid brick;
• foam concrete.

Spacer types are made of high quality nylon and steel. They can easily withstand large temperature changes, so they are used at construction sites in Siberia and the Far East. Their high bearing capacity made it possible to work with them on oil and gas platforms. Expansionless anchors are used in installation under conditions of small distances between the axis and the edge.
