Anchor Conical Plastic - For Sale in South Africa at Communica

Conical Plastic Anchors - The Fastener Standard for SA Installers

Anchor conical plastics are a staple for electricians, DIYers, engineers, and installers across South Africa. These expansion fasteners are designed for quick, secure, and low-cost mounting of items to brick, block, plaster, or drywall. With their flared design, conical plastic anchors grip the substrate as the screw is driven in, preventing spin or pullout. That's why they're trusted for mounting electrical boxes, shelving, lighting, signage, and more.

What Are Conical Plastic Anchors?

Conical plastic anchors-sometimes called plug anchors or wall plugs-are pre-formed fasteners that expand against the sides of a drilled hole when a threaded screw is inserted. They're widely compatible with a range of screw sizes and are valued for:

• Quick, mess-free installation
• Suitability for brick, plaster, concrete block, and drywall
• Cost-effective bulk pack availability
• Resistant to corrosion and rot (unlike metal variants)

Sizes, Materials, and Applications

*Typical load capacities are for solid brick. Reduce for hollow or weak substrates.

Where Are Conical Anchors Used?

• Wall-mounting enclosures, conduit, and DB boards
• Fixing shelves, brackets, cable trays
• Securing signs, access points, monitors
• Educational workshops & maker spaces

Choosing the Right Plastic Anchor for Your Project

Selecting the right size anchor conical plastic is crucial for a safe and long-lasting installation. Key factors to consider:

• Wall Material: Solid brick or block provides better holding versus hollow substrate-use longer/fatter anchors for weaker walls.
• Required Load: Heavier items (e.g., UPS brackets, large power strips) call for 8mm or 10mm plugs.
• Screw Compatibility: Match the anchor size to your screw diameter and length for full engagement.

Installation Guide (Step-by-Step)

1. Drill a hole of matching diameter and sufficient depth for the anchor.
2. Clean out dust with air or a brush to ensure full expansion.
3. Insert the anchor flush to the surface.
4. Drive in the screw-do not overtighten, as this may split the plastic or wall.

Example Calculation: Load Safety Factor

If your bracket weighs 12 kg and you want a 3x safety margin, aim for an anchor with at least 36 kg rated load. For brick walls, two 8x40mm anchors (~22 kg each) provide a safe setup for most household items.
