Thin Nylon Insert Nuts 3/4-10 10pk

The Thin Nylon Insert Nuts 3/4-10 10pk from ALLSTAR PERFORMANCE are essential fastening hardware designed for marine applications where vibration resistance and reliable hold-fast performance are critical. These nuts are particularly useful for securing deck hardware, engine manifolds, and structural components on boats or trailers.

Constructed with a 3/4-10 thread specification, these nuts feature a nylon insert (also known as a nyloc feature) that creates friction against the bolt threads, effectively locking the fastener in place without needing a secondary lock washer or threadlocker compound. The thin profile design allows for installation in tight spaces common to marine engine bays and transom assemblies, where standard full-height lock nuts may not fit.

Engine builders, boat fabricators, and maintenance-focused anglers will benefit from these dependable vibration-locking hardware solutions. They are particularly effective for securing trim tabs, prop shaft hardware, fuel system fittings, and electrical connections, where loosening could lead to significant issues.
