Anchor Conical Plastic for Sale in South Africa - Secure Your Installations with Confidence

Why Choose Conical Plastic Anchors?

Conical plastic anchors are a staple fastening solution for mounting items to concrete, brick, drywall, and block materials where direct screwing is not advisable. Their expanding, wedge-shaped design provides secure grip in drilled holes, preventing pull-out and damage to the surface. At Communica, you'll find a range of sizes ideal for electricians, students, facilities teams, builders, and hobbyists needing reliable everyday fixings.

Key Features and Material Specifications

• Made from strong polypropylene or nylon for long-term durability and non-corrosive performance.
• Grip ribs or wings resist rotation and slip inside the hole even in crumbly substrates.
• Accept standard metric or wood screws for simple installation using basic hand tools.
• Colour options (usually grey or red) to differentiate anchor grades and improve visibility in builds.

The table below compares some common conical anchor variants available at Communica branches. Check packaging for manufacturer specifications and safe working loads (range: 10-80N, not suitable for heavy or structural loads):

For most projects, keep a variety of anchor sizes on hand to suit both small electrical work and medium-duty wall fixing. Communica provides VAT invoices for business purchases and stocks both single packs and bulk bags for larger trade requirements.

Selecting the Right Anchor Size and Quantity

To ensure strong mounting, match the anchor type and size to:

• The thickness/type of wall material (e.g., plaster, brick, lightweight block).
• The weight and nature of the object being mounted.
• Screw diameter and expected load per anchor point (always err on the side of larger anchors for medium-duty applications).

Estimate your project needs - measure the number of mounting points, and add extras for errors and spares. Anchor conical plastic packs at Communica typically range from 12 to 100+ units per bag, with larger packs offering better value for repeat jobs.

Installation Guide: Steps for Reliable Fixing

1. Mark fixing points accurately with a pencil or marker.
2. Use the correct masonry drill bit (per anchor size) to create a clean, perpendicular hole to depth. Clear all dust before proceeding.
3. Insert the plastic anchor flush with the wall. Tap gently if required, ensuring the grip flanges do not buckle.
4. Drive the screw through the fixture into the anchor until secure. Avoid overtightening, as excess force can split the anchor or fracture the plaster.

Troubleshooting & Advice

• If an anchor spins in the hole, it indicates too wide a hole or crumbly substrate - use a larger anchor or chemical fixing if critical.
• For hollow walls (gypsum/drywall), consider specialist cavity anchors or toggle bolts from the same category.
• Always verify load requirements. For loads >5kg per anchor, choose longer, thicker grades or switch to nylon expansion anchors if suitable.
• If re-using existing holes, inspect for wear or loose fit. Replace with a wider anchor if in doubt.
