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.
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.
Order was complete and quality was great, thanks Fairwinds.
Never ordered from Rob at Fairwind fasteners before and I was so pleasantly thrilled with the extent of knowledge and fast service. Going straight here from now on and not even looking elsewhere. Thanks again, tremendously.
