Self-Locking Nut Low Standard Hex Lock Nuts Safety Nut Carbon Steel Nut Hex Nuts for Fasteners (10Pcs, M3)

• ✅【Standard Low Self Lock Nut】The lock nut, also known as stop nut or self-locking nut, has a plastic fastening piece made of plastic on the internal thread. The plastic deformation of the plastic part, which occurs when tightening the nut, prevents the threaded joint from loosening on its own and makes other machine elements or machining of the screw shank unnecessary.
• ✅【Wide Applications】Our hex nuts are very strong and suitable for both indoor and outdoor use. For mechanical engineering, automobiles, motorcycles, models, fence construction, furniture, etc.
• ✅【Excellent Workmanship】When using high-quality stainless carbon steel, the lock nut can be used not only in dry rooms but also in wet rooms and outdoors.The high hardness ensures a long service life.
• ✅【Hex Nuts】Lock nuts are a new type of anti-vibration anti-elastic parts used in folding beds, cabinets, miners, cutters, textile machines, etc.
• ✅【Self-Locking Nut】Lock nuts are disposable. Once such a connection is loosened, the locknut becomes unusable and must be replaced. So there is no longer any protection against independent loosening.
