Frequently asked questions about the Dowels category
What are dowels?
Dowels — это plastic or two-component fastening elements designed to securely attach fixtures and structures to walls, ceilings and other substrates. The category includes universal dowels, for aerated concrete, brick, drywall and insulation from brands such as Fischer and Hilti.
Which dowels suit drywall (gypsum board)?
For drywall use winged/toggle dowels, metal expanding anchors or nail-type Driva fixings, typically 35–50 mm long with a wide expansion. The range includes drywall-specific items such as KIPSITÜÜBEL 4.5x50 for light shelves and picture frames.
Which dowels are for aerated concrete (gas concrete)?
Choose coarse-thread or two-component anchors designed for porous substrates, such as Fischer 6x50 SX Plus and other aerated-concrete specific dowels. They provide improved grip in soft, cellular blocks.
Which dowels to choose for brick?
For solid brick use universal plastic dowels 6x40 or 8x40 with sufficient expansion area; for hollow brick choose anchors with large expansion or chemical anchors. The range includes Fischer 8x50 and universal 6x35/6x40 options.
What are 6x40 mm dowels used for?
6x40 mm dowels are a universal size for light to medium loads such as shelves, rails and brackets. They are commonly used in solid brick, concrete and denser aerated blocks when paired with appropriate screws.
How do Fischer dowels differ from ordinary plastic dowels?
Fischer dowels typically feature improved geometry and two-component designs that provide better expansion and pull-out resistance than basic plastic dowels. The range includes universal SX Plus and two-component solutions for different substrates.
What are nail dowels (naulatüüpbel/dюбели гвозди)?
Nail dowels are plastic sleeves with a driven nail; they provide very quick installation for light fixings in brick and concrete. The catalogue includes 5–6 mm diameter nail-dowel variants in lengths from ~15 to 40 mm for fast mounting.
Which dowels for insulation fixing?
Use insulation fixings with wide heads (Ø 60–140 mm) and lengths from 100 mm upward for EPS or mineral wool. The range includes INSULATION FIXING 10x100 TM 100TK suitable for foam and mineral wool insulation.
Which dowel type for light shelves and brackets?
Use universal plastic dowels 6x35–6x40 with 4–5 mm screws for light shelves and brackets. For drywall, pick special expanding or metal anchors for reliable support.
How to choose dowel and screw length?
The dowel must be fully embedded: thickness of the fixture + embedment depth in the substrate = dowel length. The screw should engage the dowel by 10–15 mm; for a 6x40 dowel use screws around 4.0x40–4.2x45 mm.
