Marine Fasteners RP-1333 Nylon Insert Lock Nut 10-32 100-Pack

The Marine Fasteners RP-1333 is a 100-piece pack of #10-32 nylon insert lock nuts (nylock nuts) engineered for reliable fastening in marine, powersports, and high-vibration applications. These hex-style lock nuts feature an integrated nylon collar that deforms as the mating bolt passes through, creating a secure friction fit that resists loosening caused by vibration, shock, and thermal cycling.

Key Features:

• Thread Size: #10-32 UNF (Unified Fine Thread)
• Type: Nylon insert lock nut (nylock / prevailing torque nut)
• Quantity: 100 pieces per pack
• Nylon insert grips mating threads to prevent unintentional loosening
• Hex profile for easy installation with standard wrenches or sockets
• Suitable for use with machine screws, bolts, studs, and threaded rods
• Ideal for marine hardware, engine compartments, deck fittings, and equipment mounts
• Reusable in low-vibration applications; replace if nylon insert shows wear

Packaged in a convenient 100-piece quantity, the RP-1333 lock nuts are a practical bulk supply for boatbuilders, marine technicians, and DIY enthusiasts. Their prevailing-torque design eliminates the need for additional thread-locking compounds or locking washers in most applications, simplifying assembly and reducing hardware costs.
