Product Details
Stainless Steel Lock Nuts are also known as nylon lock nuts, self-locking nuts, nylon insert lock nuts and Nyloc nuts. Nylon lock nuts are designed to increase the locking force and prevent the nut from working loose. The internal nylon ring has no threads cut into it; it is forced to deform around the threads as the nut is twisted on, ensuring a tight grip on the thread.
For sizes 1/4-20 and larger, anti-seize thread lubricant is needed to prevent galling and breaking fastener.

I use these with s/s bolts on my boats. They work great with not having bolts loosening up.

Mike- Something wrong here - can't finis

Mike- This product was fine but I was disappointed not to be given a back order date for the balance of my order, extra shipping charges on some of the back ordered parts and finally the inability to fill the last item of my order. These were small items but still they were important to my production.

Tiny Lock Nuts Hold Tight
16 years ago
Needed to secure a bolt in a fan used for dance. The hinge got heavy use and the regular nut would come loose and fall off. Using two nuts together wouldn't do the trick so I went looking for a lock nut. Finding the size I needed was a challenge. Not everyone stocks a #4-40. Found this site and waited for a backorder to come in and couldn't be happier with what I received. I'll use this little gem in my woodworking projects, too.

Q: Hello, I am looking for a 33C throttle cable with 5 16 thread for my diesel engine on my 1975 sailboat. What can I use to adapt the standard cable with 10 32 thread to 5 16 thread? Thanks for any help you may provide. Christine Urquhart

A: I am not aware of an adaptor but you can reach out to Seastar at 610-495-4011. I think what you need is a 6400 series cable. They have 5/16 thread.

A: Back in ""the day"" these guys would ship individual quantities. It was a sad day for me when they changed that policy, though their prices were still low enough that a box of 25 was often cheaper than 10pc at the hardware store. I still have quite an inventory of extra fasteners I accumulated back in those days. Back in those days, they also stated the ALLOY in the listings, and most everything was available in 316SST. Sigh...
