TIMCO ZYP Multi-Fix Concrete Screw - 7.5 x 100 - Yellow - Box of 100

Used these to fix 2x3 CLS into brick and concrete walls of the outhouse of my no-fines concrete house to build heavy duty shelving. Used an Erbauer impact driver after drilling a 6 mm pilot hole, and they mostly bit down smooth and clean. In breeze block and standard brick they went in without any drama — solid grip, no spinning, no tearing. Old Victorian brickwork was harder going, but that’s just the nature of the material. On a couple of holes the dust compacted at the bottom and stopped me getting a fully tight fit, but that was user error rather than a problem with the screws. The fixings themselves performed exactly as expected. Despite driving them on max power, I didn’t chew a single T30 head. They held up perfectly and felt strong all the way in. A slightly larger pilot — 6.5 mm or even 7 mm — would probably have made the job smoother, but I didn’t have those sizes to hand. Even so, the screws still bit well and held firmly. For a box of 100, they’re very good value for money — especially compared to other brands that only sell packs of 10 or 20 at a higher price per screw. Good: Bites cleanly with correct pilot hole, strong hold, T30 heads don’t strip, excellent value in the 100‑pack Bad: Harder work in old Victorian brick (expected), needs proper dust clearing for best results

very good value Concrete Screw. they work well and are strong. thanks

I have now purchased several lengths (80mm, 100 and 120), these are superb fixings, have used them through concrete paving slabs and timber. Strong wrists are required where concrete is required, I found screwing clockwise then anti clockwise a bit a time to cut your way through worked best. In timber they are brilliant, just make sure you use a 6mm diameter (as indicated) sharp drill. Profiled screw driver bit for the head is supplied making tightening (and untightening) a doddle.

The 7.5mm diameter is perfect for most anchoring jobs, and the screws have a sharp thread that bites into concrete without much effort. The coating on the screws seems durable, offering some protection against rust and wear. Overall, they feel reliable and strong enough for a variety of heavy-duty tasks. Ease of Use: Installation was straightforward. I pre-drilled the holes in the concrete, and the screws went in easily, holding tight once they were in place. The multi-fix feature makes them versatile, and they stay secure without any wobbling. I used just a few for my shed, and they worked perfectly, but now I have loads left over for future projects! Performance: These concrete screws hold up well. After using them to anchor the shed, I haven’t had any issues with them loosening or shifting. They grip tightly, and the shed feels secure. They work exactly as expected, providing strong, reliable anchoring for concrete surfaces. Value for Money: For the price, this pack of screws is a great value. I only used a few for my shed, so now I have a ton left for future projects. They’re durable, reliable, and can be used for a wide range of tasks, making them worth the investment. If you’re looking for a solid anchoring solution, this is a good choice. Pros: Strong, durable screws that hold well in concrete Easy to install with a pre-drilled hole Versatile and can be used for a variety of tasks Good value for money, especially if you only need a few screws Cons: If you don’t need many, you might end up with extra screws left over May not be the best choice for tasks requiring larger anchors or heavier loads Final Thoughts: The TIMCO ZYP Multi-Fix Concrete Screws are perfect for anchoring my shed securely. They’re easy to use, strong, and provide reliable performance. While I only needed a few, now I have loads left over for future projects. If you’re doing a concrete anchoring job, these screws are a solid, affordable option.

So easy to use, drill a 6mm hole and screw in. Be careful if you need to screw in and out these as this will then make the screw have less grip. Good quality screws, come with a bit although I didn't use it so can't comment on if it was good.

Great Product

These are excellent screws for fixing into concrete and brickwork. Much easier to install and cheaper than using those expanding concrete anchors and bolts. These are also good for fixing things to the wall if you have insulated plasterboard lining the walls of your house, as they are sturdy, and long enough to get through to the brickwork behind. Just be aware these screws are 7mm thick so might not fit through predrilled holes on whatever you are trying to hang. This price was also better than screwfix or toolstation, good value.

I have used loads of these in the past handy to keep in the garage

Wir nutzen die Schrauben um eine Ungterkonstruktion für eine Vertäfelung an die Wand zu montieren. Bei diesen Schrauben spart man sich die Dübel. Einfach mit dem passenden Bohrer direkt durch die Dachlatten (odewr was man als Unterkontruktion nimmt) bohren und die Latte dann mit den Schrauben befestigen. Dafür sollte natürlich ein passender und Qualitativ hochwertiger Torx-Bit in einem starkem Akkuschrauber verwendet werden. als Heimwerker sollte das aber selbstverständlich sein. Für die Schrauben gibt es eine klare Kaufempfehlung.
