[100 PKG] Hex Lock Nuts Nylon Insert Grade C Medium Carbon Phosphate Oil 1/4-20

Hex Lock Nuts Nylon Insert Grade C Medium Carbon Phosphate Oil 1/4-20 are high-precision, vibration-resistant fasteners designed to secure assemblies with confidence. This nylon insert lock nut, commonly known as a Nylock nut, integrates a durable nylon element that creates friction against the bolt threads to resist loosening under shock and vibration. Finished with a phosphate oil coating, these nuts offer added corrosion protection and smoother operation in a range of environments.

• Material: Grade C medium carbon steel for strength and durability
• Locking Mechanism: Nylon insert provides reliable resistance to loosening
• Thread Size: 1/4-20
• Finish: Phosphate oil coating for lubrication and corrosion protection
