We've been running these through salt spray for 500+ hours and they hold up pretty well under heavy vibration—65Mn spring steel at HRC 45-48 gives them that bite.
Basically, the wedge locks against bolt loosening when you've got loads shaking everything, and the Dacromet coating handles the -196°C to +800°C range so heat cycles aren't an issue.
One thing to know: they won't suit precision instrument assemblies where you need near-zero height tolerance—these are more for heavy machinery maintenance.
tempearture range is that wide (check our COA on specific batches), and your M3 through M80 sizes are covered in bags of 1000.
But we usually have stock on most sizes, though teh M10 might run 20 days or so for larger orders over 50 units.
Actual handling detail—the wedge face tends to pick up oil sediment, so give them a quick degrease before insallation.
Our standard MOQ is 5000 pieces per size, but we can negotiate smaller quantities for first-time orders or custom projects—just reach out to our sales team.
Lead time is usually 15-20 working days for standard sizes after order confirmation, plus shipping time. For rush orders, we can sometimes expedite to 10 days.
Yes, we can provide a third-party salt spray test report confirming 500+ hours resistance, along with material certificates for the 65Mn spring steel and hardness test reports.
We can manufacture sizes outside M3-M80 range, but it requires custom tooling and slightly longer lead time. Just share your exact dimensions, and we'll quote you.
Keep them in the original packaging, in a dry, indoor environment with temperatures between 0°C and 40°C. Avoid exposure to moisture or chemicals to preserve the Dacromet coating.
