Seachoice RP-SC1335 Stainless Steel Nylon Insert Lock Nut 1/4-20

The Seachoice RP-SC1335 is a 1/4-20 nylon insert lock nut constructed from corrosion-resistant stainless steel, ideal for marine, automotive, and general fastening applications. The nylon insert provides secure locking action that resists loosening from vibration, shock, and thermal expansion without requiring additional locking washers or thread-locking compounds.

Key Features:

• Stainless steel construction resists corrosion in harsh marine environments
• 1/4-20 thread size for standard SAE applications
• Nylon insert creates friction to prevent self-loosening
• Reusable design maintains locking effectiveness through multiple installations
• Sold in convenient 100-piece bags for bulk projects and maintenance

Nylon insert lock nuts, also known as nyloc nuts or elastic stop nuts, are essential hardware for any application where fastener security is critical. The nylon insert grips the mating threads to create a prevailing torque that keeps the nut securely fastened even under continuous vibration.
