Metric Hex Nuts & Nylon Insert Lock Nuts Assortment — 276Pcs M2–M12 for Every Fastening Need

Whether you're assembling flat-pack furniture, servicing a vehicle engine bay, securing machinery panels, or tackling a home renovation, this set delivers the metric hex nut and locknut sizes you reach for most — sorted, labeled, and ready to use.

Frequently Asked Questions

What is the difference between the hex nuts and the lock nuts in this kit?
The hex nuts are standard metric fasteners used for general clamping and assembly. The nylon insert lock nuts (also called nyloc nuts) have a blue nylon ring at the top that grips the bolt thread under friction, preventing the nut from loosening due to vibration or dynamic loads.
Are these nuts compatible with standard metric bolts and screws?
Yes. All nuts in this kit follow ISO metric thread standards and are compatible with standard metric bolts, screws, and threaded rods in the corresponding size (M2–M12).
Can the nylon insert lock nuts be reused after removal?
Yes, they can be reused multiple times. The nylon insert retains sufficient elasticity for repeated use, though locking performance may gradually reduce after many cycles. For critical safety applications, replacing with a new nut is recommended.
Are these nuts suitable for outdoor or marine use?
304 stainless steel offers good corrosion resistance in most outdoor environments and is suitable for general outdoor use. For highly corrosive marine or coastal environments, 316 stainless steel is typically recommended for maximum protection.
What tools do I need to install these nuts?
A standard metric spanner or socket set is all you need. The hex profile fits any standard open-end, ring, or socket wrench in the corresponding metric size. No special tools are required.
How are the nuts organized in the storage case?
The clear plastic case has multiple labeled compartments, with each size stored separately. This makes it easy to identify and retrieve the correct nut quickly without sorting through a mixed pile.
Is this kit suitable for children or beginners?
This kit is not suitable for children under 5 years old due to small parts. It is well-suited for adult beginners — the organized case and broad size range make it easy to find the right nut without prior fastener knowledge.
276 metric nuts. Two types. One organized kit. Add to cart and have the right fastener ready for every job.
