Works well but requires firm pressure

The product works, but you really need to push hard to get them started in denser insulation boards. Once in, they are solid. Just be prepared for some arm fatigue.

Good grip, easy install

Works exactly as described on standard drywall. I deducted one star only because the box labeling was a bit confusing, but the screws themselves are excellent quality.

Sturdy and reliable

Used these to hang heavy mirrors in a renovated office. No sagging after three months. The zinc coating looks durable too.

Best expansion screw I've tried

I have tried many different types of anchors for Eterboard, and these are by far the easiest to install. No cracked boards and no loose fittings.

Perfect for fiber cement boards

I was skeptical about using these on harder fiber boards without drilling, but they penetrated easily and provided a very secure anchor for my shelving brackets.

Huge time saver on big projects

I used these for a large commercial ceiling installation. The fact that I don't need to pre-drill saved us hours of labor. They drive in smoothly and hold tight.

5 FAQ

Q: Are these rust-proof for outdoor use?

A: They feature a yellow zinc plating which offers good corrosion resistance for indoor environments. However, they are not rated for direct exposure to rain or harsh outdoor weather conditions.

Q: What size drill bit do I need for installation?

A: You do not need any drill bit. These are 'drive-in' screws designed to be installed directly into the board using a Phillips head screwdriver or an impact driver with low torque settings.

Q: Can these be used on concrete walls?

A: No, these are specifically designed for gypsum, fiber cement, and insulation boards. They will not expand correctly or hold securely in solid concrete or brick.

Q: Do you offer bulk pricing for orders over 50 boxes?

A: Yes, we offer tiered wholesale discounts for bulk orders. Please contact our sales department directly through the 'Contact Seller' button for a custom quote.

Q: Is the 50mm length suitable for hanging a TV mount?

A: For a TV mount, we recommend checking the specific weight of your TV and the thickness of your wall board. While strong, we generally suggest distributing the load across multiple anchors or using studs for heavy electronics.
