10-Piece Magnetic Pentagon Head Screwdriver Bit Set Metric Sizes 1/4 Inch Hex Shank 5 Sided Security Tamper Proof Screw Driver Drill Bits, 50mm/2inch Length for Power Drills and Impact Drivers

I get it, companies don't want you messing inside of some of the stuff they sell. That could be fine if the devices worked and they din't charge an arm-an-a-leg to fix (plus shipping and handling). So, security screws gotta go. The Saipe 10 piece did the job. I actually tried a bunch of other hacks to get the security screws off, but they were in too well. Glad we found these. Fit perfectly. Certainly seem sturdy and long enough for what they need to be doing.

I use it to remove security bolts.

I've not used them yet but I'm giving 5 stars just because they match up with my pentagon head screws (these bits are almost impossible to find). I'll update my review once I find out how well they actually perform.

I was working on a project and couldn't find a tool to fit, upon further inspection, found the screw to be pentagon 🤔 now I have 2 sets for 10 bucks. Probably never need them again, but I got em now 😊

Why would you have a 10-piece set without all the sizes, it's just multitudes of the sizes they think you'll need the most it's a tamper proof bit set, they're going to use weird sizes, you need them all, what a waste of time

NiceGood product

Exactly what I needed

Like others have said, this is the same 2 of the same 5 bits. Unnecessary for most and I would avoid if you don't really need it. They seemed sturdy and durable though but did not work for my application
