Heavy Duty Metal Fence Spikes-Anti Climb Security Spikes for Fence and Wall-Intruder and Animal Deterrent（Size74 inches）

So I had to build a 10 foot security pole to watch over our neighborhood mail box due to break-ins recently. I added the Spikes to it to deter vandals and thieves from trying to climb up and steal the lights or cam. They are really sharp and strong. Easy to install.

I know I would avoid a house like this if I had to climb a fence. It's a little hard to know if they're working. We were burglarized previously but not since. Little bit like Homer Simpson and the Bear repeller. Seems to be working.

These are very sturdy metal spikes! They are heavy duty and heavy. These are not easily bent. They will deter humans and animals from climbing your fence. The spikes are very sharp.

These spikes are well made. Quite sharp so, will need care while fixing them on fence. As mentioned in few other reviews the screws provided in each box are lesser than the holes in the spikes. So, if you buy this product, either get extra screws separately or just use the screws for the end holes of the spikes to fix. For this price of the product they could have included more screws.

Item is overall good and serves the purpose. The annoying thing is that only half the self-tapping screws were included. This now means that I have to make a trip to a distant hardware store to purchase 10 screws. I was hoping for a rapid DIY project that has now turned into a hassle due to missing screws. There does not seem to be a way to contact the vendor about this and I don't want to to deal with a return based on these screws.Addendum: I bought the screws but it was difficult. The screws are self-tapping and have a little rubber washer attached to them. I had to find #10 screws (1") and then buy the rubber washers separately. Without those rubber washers it doesn't grip as satisfactorily. I actually had to go to two different harware stores to find both those items. An extremely annoying experience for something that should have been done properly in the first place. An otherwise good product whose reputation is damaged by a silly omission.

These things are hardcore. The washers could be bigger, but besides that, these things definitely do the trick of making our fence uninviting to intruders.

I had trouble installing them but I used cement to hold them down and it seems to be fine.

2 stars because so far the spikes seem to be strong and good quality however the screws/ washers were all too small that they fit right through the hole making it impossible to install. Had to go to Home Depot to get bigger screws and washers to actually install it.
