Rated 4.8 out of 5 stars.
Need nuts that won't vibrate loose?
This pack of 25 nylon insert lock nuts is perfect.
They're size #12-24, which fits a standard #12-24 bolt or screw.
The magic is in the nylon ring inside the top of the nut – when you screw it onto a bolt, the nylon grips the threads, creating friction that prevents the nut from backing off on its own.
They're made from 18-8 (304 / A2) stainless steel, which is highly corrosion and rust resistant, making them great for both indoor and outdoor projects.
The hex shape is standard for use with a wrench or socket.
These are also called prevailing torque nuts or elastic stop nuts.
They're reusable for a few times before the nylon insert wears out.
A versatile, high-quality fastener to have in your workshop for automotive, machinery, furniture, or any assembly where vibration is a concern.
Packaged in the USA.
