Grade 8 Nylon Insert Lock Nuts – Fine Thread – Yellow Zinc – 250 Piece Assortment Kit
About this item
Got a project that needs serious fastening?
This 250-piece kit from WARREN FASTENINGS SOUTH is packed with nylon insert lock nuts.
They're Grade 8 strength, so they're tough, and they have a fine thread pattern.
The yellow zinc finish adds corrosion resistance and gives them that classic industrial look.
They're external hex drive, so you can wrench them down tight.
The nylon insert inside prevents them from vibrating loose, making them perfect for automotive, machinery, or any application where things shake.
This kit gives you a variety of sizes to cover your bases—all fine thread, all Grade 8.
No more running to the hardware store mid-project.
Just open the box and grab what you need.
They're brand new, organized, and ready to work.
Stock up and be prepared for any job that needs a lock nut that stays put.
