Seachoice RP-MP1335SC Stainless Steel Nylon Insert Locknut 1/4"-20

The Seachoice RP-MP1335SC is a corrosion-resistant stainless steel locknut designed for marine and outdoor applications where vibration resistance is critical. This 1/4"-20 threaded fastener features a nylon insert that creates friction against bolt threads, preventing loosening from vibration and movement.

Key Features:

• Stainless steel construction resists rust and corrosion in marine environments
• Nylon insert provides secure locking action without requiring thread deformation
• 1/4"-20 thread size fits standard bolts and studs
• Reusable design allows for multiple installations
• Sold in convenient 6-piece bag for stocking common sizes

Nylon insert locknuts, also known as Nylock nuts, are ideal for securing hardware on boats, trailers, and marine equipment where exposure to moisture and vibration could cause standard nuts to loosen over time. The nylon ring maintains tension even in wet conditions, making it a reliable choice for critical fastening applications.
