M24‑2.00 DIN 439B Hex Jam Nut – Class 04, Fine Thread, Plain Finish

The M24‑2.00 DIN 439B hex jam nut is a precision‑made, low‑profile locking nut designed for fine‑thread metric fastening applications where space is limited and secure locking is critical. Manufactured to DIN 439B specifications with a Class 04 strength rating, this jam nut is used in conjunction with a standard hex nut to prevent loosening caused by vibration or dynamic loads. The 2.00 mm fine thread pitch provides increased thread engagement, improved clamping control, and enhanced resistance to back‑off. Supplied with a plain (uncoated) steel finish, it is ideal for controlled environments, machinery assemblies, and secondary locking applications.
