Hey DIYers and workshop folks! Need some tough, reliable screws? Grab this pack of 100 M4 x 10mm countersunk bolts from uxcell. They're made from 10.9 alloy steel, which is super strong and hard-wearing. The black finish helps with corrosion resistance, so they won't rust up on you. They've got a hex socket head (that's the star-shaped hole), so you just need a matching hex key to drive them in. They're flat-headed, so they sit flush with the surface for a clean look. The thread pitch is 0.7mm, total length is 10mm (about 0.4 inches), and the head size is 8mm across. They come with all the specs you need: head size, drive type, everything. Perfect for metalwork, machinery, furniture, or any project where you need a solid, low-profile fastener. At 100 pieces, it's a great value pack that'll last you through plenty of jobs. No more searching for that one screw – you'll have a whole bunch ready to go.
