Seachoice RP-SC3552 Stainless Steel Nylon Insert Lock Nut - M6-1.0

The Seachoice RP-SC3552 is a metric M6-1.0 nylon insert lock nut manufactured from corrosion-resistant stainless steel. This fastener features a nylon insert ring that creates friction against the bolt threads, preventing the nut from loosening due to vibration or dynamic loads—making it ideal for marine, automotive, and outdoor applications where reliability is critical.

Key Features:

• M6 x 1.0mm metric thread size for compatibility with standard metric bolts
• Stainless steel construction provides excellent corrosion resistance in saltwater and harsh environments
• Nylon insert locking mechanism prevents self-loosening without requiring additional lock washers
• Reusable design allows for multiple installations while maintaining locking performance
• Sold in convenient 100-piece bags for stocking and larger projects

Nylon insert lock nuts (also called Nylock nuts or elastic stop nuts) are essential hardware for boat rigging, trailer assemblies, deck hardware mounting, and anywhere a secure, vibration-resistant fastening solution is required. The stainless steel material ensures long-lasting performance even in challenging marine conditions.
