Need nuts that won't shake loose? This 80-pack of nylon insert lock nuts is your solution. They're the standard hex style, but with a special nylon ring (or collar) inside the top. When you screw them onto a bolt, the nylon creates friction against the threads, 'locking' the nut in place to resist vibration and loosening over time – way more reliable than a regular nut and washer. They're made from quality 304 Stainless Steel, which offers excellent corrosion and rust resistance, making them ideal for outdoor projects, automotive use, marine applications, or anywhere moisture is a concern. The thread is 1/4-20 UNC (coarse thread), a super common size for all sorts of DIY, automotive, and industrial projects. This bulk pack is fantastic for mechanics, hobbyists, or anyone who does a lot of repairs. Keep a bunch in your toolbox so you always have them on hand. Just remember, they're considered a one-time-use item in critical applications because the nylon can wear after removal. For trailers, ATVs, furniture assembly, or general shop use, they're incredibly handy and reliable.
