DIN Compliant Locking nut

For general machinery and equipment, DIN Compliant Locking nuts are a must—they keep bolts from coming loose when there’s constant vibration. Most are hexagonal, and some have a nylon ring or a deformed thread to make sure they fit tight. We can offer good prices because we make them in large quantities. If you order more than 20,000 units, you get a 5% discount. These nuts usually come in natural finish or zinc-plated. We ship them by ground freight because it’s cost-effective. They’re packed in strong, sealed cartons so moisture doesn’t damage them. We check their quality with torque and vibration tests, and we provide ISO 9001 certification.

For the auto industry, DIN Compliant Locking nuts are used in important parts like wheel hubs and engines. They keep the clamp load steady when the car is moving and under dynamic forces. Most of these nuts are hexagonal and have a metal locking part that holds up well. We offer good prices for auto suppliers. If you order more than 50,000 pieces, you get a 7% discount. The common finishes are zinc with yellow chromate or clear chromate. We have regional warehouses, so we can deliver quickly. The packaging is waterproof and can stand shocks. All the parts meet the relevant auto standards.

Q: What is the fundamental principle that allows a DIN Compliant Locking nut to resist loosening under vibration?

A:It utilizes design features that create a persistent friction force against the bolt threads. This is achieved through various methods, such as a deformed top section, an integrated non-metallic collar (nylon insert), or a free-spinning washer that bites into the bearing surface. This constant resistance ensures the nut maintains its clamp load and prevents the rotational loosening that plagues standard nuts in dynamic environments.
