We had a batch come through last month for a rail fastening system where teh custmer needed M24 in 316, and the ±0.1mm inner diameter tolerance was only thing that kept their assembly form binding under thermal cycling—pretty much every other suplier they’d tried was running ±0.15mm or worse.
Hardness sits at HRC 38-45 for all three grades, which is actually tighter than most DIN spec washers we’ve tested, and the thickness tolerance is ±0.05mm across the board from M1.6 up to M48, but you’ll want to note that the outer diameter tolerance is ±0.15mm (usually not critical unless you’re stacking them in a tight bore).
These work fine in most industiral fastening systems—think automotive subframes, valve covers, or light structural bolting—but they’re not suited for anything above 120°C continuous, because the carbon steel loses its spring temper past that point, so don’t try them on exhaust manifolds or turbine housings; we usually have stock on M8 through M20 in 304, but confirm lead time for 316 or anything below M3.
MOQ is 5000 pieces, lead time runs 15-30 days depending on the size and material mix, and our company can do custom thicknesses or odd inner diameters if you need them, but the ±0.05mm tolerance stays locked.
Our MOQ is 5000 pieces regardless of size or material, so M6 in 304 would need at least 5000 pieces.
Yes, we can supply a mill test certificate for 316 material on request. Just let us know when you place the order.
Custom sizes outside that range typically add 5-10 days to the standard 15-30 day lead time, depending on tooling needs.
The temperature range is fine for most outdoor conditions, but for corrosion resistance outdoors, we'd recommend 304 or 316 over carbon steel.
We default to plastic boxes for moisture protection, but paper boxes are available if you specify that. Just mention it in your order notes.
