Natalie X. ★★★★★

For a full box of 2500, every single screw has come out of the package with clean threads and a consistent hex broach—no duds so far. The low head profile is a lifesaver in tight jig setups where standard caps won't clear. Just wish the box had a resealable lid, but that's on me for buying in bulk.

Julian ★★★★★

These are exactly what I needed for a tooling fixture rebuild, and the 8.8 alloy steel gives me confidence they'll hold up under repeated torque. The low head profile is a nice touch for tight clearance spots, and at 2500 per pack I won't be running out anytime soon.

Abigail ★★★★☆

The hex socket drive on these M4 bolts engages nicely without stripping. They’re a solid choice for mounting jigs, though I wish the threads had a bit more lubricant out of the box. Still, at this price for 2500 pieces, you can’t beat the value.
