20Pcs M4 X 20mm Hex Button Head Screws - 304 Stainless Steel Socket Cap Bolts With Nuts

About This Product

For all the DIYers and repair folks out there, this set of M4 x 20mm hex button head screws is one of those things you don't realize you need until you have them, then you find uses for them everywhere! The 304 stainless steel construction means they're corrosion-resistant and won't rust, which is huge for outdoor projects or anything in damp environments. The button head design sits flush when installed, giving things a clean, professional look while the hex socket drive allows for higher torque without stripping. Each screw is 20mm long with M4 threading (that's about 0.79 inches for those who think in imperial), with a 7.5mm head diameter. The package includes 20 pieces, which is enough for multiple projects without leaving you with just one or two extras. The threads are clean and precise, so they start easily without cross-threading, and the finish is smooth without burrs that can damage your materials. You'll need a 3mm hex key to install them (not included), but once you start using these, you'll appreciate how much better they work than Phillips head screws that always seem to strip out. Perfect for furniture assembly, machinery repairs, electronics projects, automotive work, or any situation where you need a strong, reliable fastener that looks good too. The 304 stainless steel has that nice balance of strength and corrosion resistance without the premium price of marine-grade hardware. Seriously, having a set of these on hand saves so many trips to the hardware store for 'just one specific screw'!
