Hillman 3760 8 x 1/2 in. Aluminum Hex Washer Head Sheet Metal Screw (25-Pack)

I use these with my Vibram soled Simms G3 fishing boots instead of the larger and much more expensive ($30-$40) Simms Alumibite cleats. 10 screws per boot really helps me with grip when wading. I just screw them into the tread blocks of my boots. Never lost a screw so far. You do need to keep an eye on the wear to the screw heads after several outings to ensure you can remove them as they wear down, but for me it's been a good trade-off considering the value here ($12.50 for 25 aluminum screws). I get around 7 outings or so with these, each outing being around 2-4 hours in total, with hikes of 2-5 miles roundtrip over dirt, rocks, asphalt parking lots, roads, etc.

I bought these Hillman 3760 screws specifically because they’re aluminum, and they’ve performed as expected. If you’re using them in environments where corrosion is a concern—like HVAC work, aluminum trim, or light-duty outdoor projects—these are a great fit.They thread cleanly and the integrated washer head offers good holding power without the need for a separate washer. Perfect for joining soft metals, plastics, or light wood without worrying about rust down the line.Why not 5 stars?Only because aluminum has its limitations—these will snap if over-torqued or used in structural applications. That’s not a flaw, just something to be aware of. I’d also recommend hand-tightening or using a driver with a clutch to avoid stripping the head.If you're looking for strength, go with steel. If you need rust-free fasteners that are easy to work with and play nice with other non-ferrous materials, these do the job well.

Over priced and incorrect.

I bought these to secure my solar panels to the aluminum frames of my system. They work great as I'm not able to use steel or other screws due the metallurgical issues. I drilled pilot holes just to prevent any chance of the screws breaking. Happy to say, they all worked without any snapping off. Definitely recommend.
