M5-0.8 X 25mm 圓柱頭螺絲 | 按鈕頭六角驅動 | 全螺紋 | 316 不鏽鋼 (300 入/包)

I've been through a lot of cheap screws for jigs and these 316 stainless ones are a different class entirely, the button head sits flush and doesn't strip after repeated tightening. The full threading grips the whole way down, which makes a real difference when you're clamping precision assemblies.

The hex socket drive bites cleanly without stripping, and the fully threaded 316 stainless finish has held up perfectly in my saltwater-adjacent shop. For the price, getting 300 of these precision-grade screws is a solid deal.

I’ve been using these for my jigs and precision assemblies, and the 316 stainless is holding up way better than the 303 stuff I’ve used before. The full threading makes them easy to seat, and the button head sits flush without snagging. Pack of 300 is solid value for the price.
