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.
All of the silicon bronze fasteners that I have purchased are outstanding. I have placed three orders and received each within four days. I have recommended Fair Winds Fasteners to Herbie from "sailing Wisdom." Great service and my go to from here on.
these guys are great. just that simple
Fast ship, organized packaging.
I generally buy my fasteners from local sources but I had a project requiring bronze. My order was small so I added a driver bit to meet minimum billing. Items shipped quickly and the shipping fee very reasonable. I am very satisfied with my small order.
