8020 Series Flanged Button Head Socket Cap Screws - 5/16-18 X 0.687 Inch (25 Pack)

About This Product

Hey DIYers and makers! If you're working with 8020 aluminum extrusions or any T-slot framing systems, these flanged button head socket cap screws are absolutely essential. This 25-pack gives you plenty of hardware to complete your projects without constantly running to the hardware store.

These are specifically designed for use with T-nuts in aluminum extrusion systems. The 5/16-18 thread size is super common in these applications, and the 0.687 inch length is perfect for mounting brackets, plates, and other components to your extrusions.

The flanged button head design is actually really smart - the low domed head looks clean and professional, while the wider flange provides better bearing surface and distributes pressure more evenly. You get that finished appearance without needing separate washers.

They're made from steel with a black zinc finish that not only looks good but provides decent corrosion resistance. The 3/16 inch Allen hex drive means you can get good torque on them without stripping, and the full threading allows for flexible positioning.

What's great about these is how reusable they are - unlike some fasteners that wear out, you can install and remove these multiple times without issues. Perfect for prototyping or projects that might need modifications down the road.

Whether you're building workbenches, CNC machines, 3D printer frames, or any project using aluminum extrusions, having a supply of these quality screws on hand will make your life so much easier. No more mixing and matching random hardware that doesn't quite work right.

At 25 pieces per pack, you've got enough for current projects and future repairs or expansions. The quality is solid - these aren't cheap imports that will strip or break when you need them most. Your extrusion projects deserve proper hardware, and these deliver exactly that!
