Picking the right material for wave Single coil spring lock washers depends on what you need them for. Carbon steel (like SAE 1074) is strong and works for most everyday uses. 316 stainless steel can be used in salty marine environments or chemical environments, and copper alloys can be used in electrical devices to help prevent bolts from sticking together in electrical devices.For high-temperature situations, like in aerospace, Inconel 718 is the go-to. If you need non-magnetic options, such as for medical imaging devices, titanium is a good choice.

The hardness of the material (measured as HRC 40-52) matters too,it balances how much the washer can flex and how well it resists wear. Certifications like RoHS or REACH make sure the materials meet environmental rules, so choosing the right one is important for both how they work and safety.

Maintenance

Taking care of wave Single coil spring lock washers means checking them regularly for dents, cracks, or rust. If any look worn out, replace them right away to keep the joint from failing. Don’t tighten them too much,over-tightening can flatten the washer and make the spring action weaker.

If you’re using the wave Single coil spring lock washers in a rusty environment, go for coated or stainless steel versions. When cleaning, use gentle solvents (not abrasive ones) to get rid of dirt, and store them in dry places to prevent rust before use.In most cases, there is no need to add lubricant, some coatings are inherently lubricating, so check first. Follow our advice on how tight to tighten and when to retighten, especially on components that are important to keeping them functioning properly.

Size selection

Q: How do I choose the right size and thickness for wave Single coil spring lock washers in heavy-load applications?

A: When picking wave Single coil spring lock washers for heavy loads, you need to balance how much weight they can hold, the bolt size, and how thick the washer is. Thicker spring washers (like those following the DIN 128 standard) have more springiness, so they can handle bigger forces without getting flattened. Make sure the washer’s inner diameter matches the bolt shaft,if it’s too loose, it won’t grip well, and if it’s too tight, it might line up wrong.

You should calculate the axial loads you expect. For example, M12 bolts with 12mm spring washers usually handle up to 150N/mm² of stress. Check engineering tables or use software to choose the right size. Don’t go too small,they might fail under load or too big,it’s a waste of materials.
