FAQS on knock in anchor

Q: What is a knock in anchor used for?

A: A knock in anchor is a mechanical fastener designed to secure objects to concrete, masonry, or brick. It is installed by hammering it into a pre-drilled hole and expanding when a bolt is threaded into it. This provides a strong, reliable hold for fixtures or equipment.

Q: How do I install an anchor bolt M12 size in concrete?

A: Drill a hole matching the M12 anchor bolt’s diameter and depth in the concrete. Insert the bolt, then tighten the nut to expand the anchor and create a secure fit. Ensure the hole is clean for optimal grip.

Q: Can an M16 size anchor bolt handle heavier loads than an M12?

A: Yes, an M16 anchor bolt typically has a higher load capacity due to its larger diameter and expanded surface area. Always check the manufacturer’s specifications for exact weight limits and application guidelines.

Q: What materials are suitable for knock in anchors?

A: Knock in anchors work best in solid materials like concrete, brick, or stone. Avoid using them in hollow or crumbling substrates, as they may fail to expand properly. Always verify compatibility with the base material before installation.

Q: Do I need special tools to install a knock in anchor?

A: Basic tools like a hammer, drill, and wrench are sufficient. Drill a hole to the required depth, hammer the anchor into place, and tighten the bolt to activate expansion. No specialized equipment is typically needed.
