M24‑3.00 DIN 439B Hex Jam Nut – Class 04, Coarse Thread, Plain Finish

The M24‑3.00 DIN 439B hex jam nut is a durable, low‑profile locking nut designed for coarse‑thread metric applications where space is limited and secure locking is required. Manufactured to DIN 439B standards with a Class 04 strength rating, this jam nut is intended for use against a standard hex nut to prevent loosening under load or vibration. The 3.00 coarse thread pitch allows for faster installation and reliable performance in general‑purpose industrial and structural assemblies. Finished in plain (uncoated) steel, it is well‑suited for controlled environments or secondary locking applications.
