#9 x 2-1/2 in. External Hex Washer Head Sharp Point Roofing Screws with Washer (60-per Pack)

I selected these number 10 metal screws made by tech to attach some metal roofing and siding to our barn. Our barn is a Morton building which has metal that is quite a bit thicker than your average metal roofing. I was surprised at how well the screws worked. The tip is very sharp and I did not have to pre-drill any of the screws because the self-tapping feature worked great. The only problem I had was torquing the screws down too far and displacing the neoprene washer by squeezing it too hard between the screw head and the metal. I set the clutch on my drill driver to a lighter setting and that fixed the problem. I believe these will last for a long time as the zinc coating should protect them from corrosion. Highly recommend the screws.

I've used similar self-drilling washer head hex screws before to fix loose corrugated fiberglass and metal roofs on our chicken shed. These Teks Coated Steel Hex Head Washer Sharp Point Screws appear to be as good or better than those I've used before. The sharp self-drilling point eliminates the need for pilot holes in all but the most extreme circumstances. The coating on the screws both protects from rusting and eases penetration into the substrate. Of course, the hex head makes them drivable with any appropriately sized socket, but an impact driver often works best with a torque limiter to prevent over-tightening which can damage the rubber washer. The rubber washer makes the screw self-sealing against leaks. I recently discovered that the rubber seal under my motorhome slide-out which was attached with a flat metal plate to the motorhome structure had come loose and was allowing mice to enter the motorhome where they made a big mess. The original 4 screws were only 1-inch #8 Phillips Head screws that had pulled out completely. I replaced those with 8 of these #10 x 1-1/2 inch roofing screws and they worked great!

As ALWAYS, Teks self-tapping fasteners are the only fastener in my experience that TRULY self-taps through the hardened steel body of Bluebird buses. All the other so-called “self tapping” screws need to be pre-drilled” - or they don’t penetrate.

We were adding a roof over our shop door as the shops roof sends all wet precipitation straight down over the entry doors and your head when entering. We used the Teks #10 roofing screw with self piercing point to attach the corrugated metal to the wooden frame. They went in one handed based on the penetrating point drilling the hole as the screw drives in. The neoprene washer sealed tightly to the roofing material and has allowed no water to leak through, as they are stated they do. They are beefy and I will use again for future projects of this nature. Highly recommend.

BACKGROUND: I have several steel sheds and want to put corrugated metal roofing over the (thin) existing roof. The Teks #10 Hex Washer drill screws looked perfect for the job. FIT AND FINISH: I have used other Teks fasteners before and these were the same high-quality appearance and feel. FEATURES: From the Teks product page with my comments as appliable. • Teks Elite sharp point roofing screws (300-pack) are designed with stronger holding power and improved waterproofing. o A great idea in a roofing screw. • The Maxi seal washer provides improved coverage of the screw aiding in better waterproofing, even when fasteners are driven at an angle. o The washers are thick enough and soft enough to provide a good seal. • The Hi-Grip threading help secure the fastener with stronger holding power, minimizing the need for rework down the road. o Not sure how well this works with corrugated roofing, but it’s there if you need it. • The new Shank guard feature reams out the hole during install, protecting the fastener's shaft and washer from sharp metal frays that could strip the protective Climaseal coating. o This is handy as it de-burs the hole in the roofing. But you do need to make sure none of the drill and reaming chips are under the neoprene washer when driving the screw down. • The Type 17 tip eliminates the need to pre-drill with a 1-step installation for secure metal-to-wood fastening. Overall, Teks Elite fasteners are designed for the Pro. Less rework. More productivity. o The type 17 is a type of drill point. IT is a sharp pointed design with a cut out flute to help capture and remove the waste allowing a self-drilling type function similar to a drill bit. • Premium finish provides exceptional corrosion resistance in harsh outdoor environments o Also good in a roofing screw INSTALLATION AND USE: The screws use a 5/16” hex head driver. They held snugly in my cheap magnetic driver bit. The Type 17 point was better for corrugated roofing as it was less likely to wander of the ridge of the corregation.. Once started they drilled, tapped, reamed, and snugged down easily. SUMMARY: Great for corrugated roofing work. PROS: Hex head easy to drive. Weather resistant coating. Good seal washer. CONS: None PHOTO CAPTIONS: 1. 300 count in this bucket. 2. Nice configuration for roofing. 3. Drove in easy and snugged down well.

INSTALLATION AND USE: The screws use a 5/16” hex head driver. They held snugly in my cheap magnetic driver bit. I did have to be careful when starting the screws as the blunter drill point would walk off the top of the corrugation. Once started they drilled, tapped, reamed, and snugged down easily.

I used the Teks #10 x 1-1/2” Steel Hex Head Elite Roofing Screws to attach some flat steel roofing material to my garage roof. They worked well. I like that they are self drilling, must faster installation. The attached washer also is a huge plus as I had no leaks, even with the strong rain that happened just after the installation. The screws also have a grey coating that makes them rust resistant. They also come in a nice plastic container that is easy to open and reseal, so I can keep my spare screws for later. Excellent product.

For my potting shed/greenhouse I had considered metal roofing but couldn’t find an installer, so decided to shingle it. I could have used these screws then. I used a similar product for the polycarbonate roof on the greenhouse, but these are better. They are thicker, #10 size, which will split narrow wood, but is fine going into 2x stock. The quick drilling tip is effective at going through the plastic material without pre-drilling. The other screws I used I had to predrill holes. They are grey in color, which will blend well with many roofing colors. They do require. 5/16 hex driver to install.

Although these specifically say "roofing screws" they also work for metal siding. We had some storm damage on the side of our pole barn and had to remove a section for repair. The existing screws were showing some wear after being exposed to weather for 15 years. Teks hex head screws with washers worked very well. Granted, the old screws were powder coated to match pole barn siding, but that's aesthetics rather than performance. When a flush-mount screw isn't needed, I can't say enough good about hex head screws: they are easier to screw down with no risk of stripping out a screw head.

Great quality screw that will attach your roofing material to the beams with little effort. The screws come with a gasket so that you don't have to stumble to put it together. The gasket will make a wonderful seal and stop any leaks from happening. This screw will penetrate many materials without having to predrill any holes. If you are going through metal you may want to use the screws that have a drill point on them. Love these screws and they made my job easy.
