Frequently asked questions about the Fastening devices category
What are Fastening devices and what are they used for?
Fastening devices are a range of products (anchors, dowels/plugs, screws, bolts, nuts, washers, etc.) for securely fixing structures to concrete, brick, wood and plasterboard. This category covers items for construction, renovation and installation tasks, including anchors for concrete and plugs for plasterboard.
How to choose the right anchor for concrete and brick?
Choose an anchor based on load, drill bit diameter and substrate: wedge and chemical anchors suit solid concrete, while expanding anchors are better for hollow blocks. Check the product's specified pull-out capacity and anchor diameter before buying.
Which dowels/plugs are suitable for plasterboard and how do they differ from wood plugs?
Plasterboard requires special plugs (expanding plasterboard anchors or metal 'butterfly' anchors) that spread load across the board. Wood plugs are usually plastic or conical and rely on solid material to grip, so they’re unsuitable for thin plasterboard without reinforcement.
Which screws to choose for outdoor use and terraces?
Choose corrosion-resistant screws with C4/C3 coating or stainless steel (A4/AISI316), such as terrace screws in sizes like 4.8x60–70. These have protective finishes and are designed for humid outdoor conditions.
How do NOVIPRO PP RUSPERT wood screws differ from ESSDRIVE?
NOVIPRO PP RUSPERT screws feature RUSPERT anti-corrosion coating and come in various sizes (e.g. 3–8 mm), while ESSDRIVE focuses on TX-drive design for faster driving and is available in PP/ZN finishes. Check the product listing for exact size and finish.
Which bolts and nuts are needed for joining metal structures indoors?
Use DIN 933/934 bolts and matching nuts, either zinc-plated or stainless A4, in the correct diameters (M5–M16) and lengths. Ensure bolt length leaves several threads beyond the nut for secure tightening.
What accessories are needed for concrete pouring and where to find them in the category?
You’ll need anchors for fixing formwork, assembly tape and other concrete pouring accessories found under "Concrete pouring accessories". Choose items rated for the working loads and compatible with your formwork dimensions.
How to choose rivets and the tools to work with them?
Choose rivets by material (aluminium/steel) and hole diameter matching your parts. Use manual or pneumatic riveters compatible with the rivet diameter — product descriptions typically state tool compatibility.
Which hooks and brackets suit hanging heavy items?
Choose steel or corrosion-resistant hooks and brackets with a specified load capacity. Check the recommended load in the product description and use anchors for concrete or suitable plugs for walls to ensure firm fixing.
