Hard to find silicon bronze nylon insert lock nuts, commonly called nyloc nuts are found right here at Fair Wind Fasteners.
Made of a guaranteed 655 silicon bronze alloy, with a nylon insert that has an inner diameter that is slightly smaller than the major diameter of your bolt's threads, locking this nut in to place and securing your fastener against coming undone due to vibration. Nyloc (nylock) nuts are known to be far more secure than lock washers.

Fast ship, great packaging and service.

FWF had what I needed
The service was prompt
the hardware came in individual envelopes to keep it organized. they were neatly labeled and of great quality. the bolts came in this vintage vibe packaging and as someone who is used to opening packaging and seeing items just thrown in, i really appreciated the attention to detail!
On the ocean, always do it right. Quality materials and quality workmanship.
Silicon Bronze from a trusted source mounting underwater hardware is critical to me. Grateful to have found Fairwinds on advice of other professionals.
