Questions about this product
- Will these stainless flange screws rust outdoors or near saltwater?
- They're A2-304 stainless steel, so they hold up well against rust, water, and mild chemicals. That makes them a good fit for outdoor, marine, and food-processing setups. For constant heavy salt spray, A4-316 stainless would resist corrosion even better.
- What does the serrated washer under the head actually do?
- The serrations bite into the mating surface as you tighten, so the bolt resists loosening from vibration. It acts as a self-locking fastener and skips the need for a separate lock washer. That's handy for trailer parts and automotive joints that shake a lot.
- What sizes come in the 10-piece set?
- The assorted set spans M4, M5, M6, M8, M10, and M12 metric threads, all fully threaded. You get 10 pieces total across those sizes. Each one has the integrated concave serrated washer built into the hex head.
