Lock Nuts M4-M12 Nyloc Steel Nylon Insert Set 100pc

A 100 piece lock nuts set covering M4 to M12, made for jobs where a more secure fixing is needed. These steel nyloc nuts use a nylon insert to help resist loosening, making them a practical choice for general fastening and repair work.

Used for garage work, workshop use, vehicle maintenance and DIY repairs, this assortment suits anyone replacing worn lock nuts or keeping common sizes ready for routine jobs. They are particularly useful on applications exposed to movement or vibration, where standard nuts can work loose over time. For servicing, fitting and general assembly tasks, having a mixed size selection close to hand makes it easier to match the right nut to the job without delaying the work.

The set includes six common metric sizes: M4, M5, M6, M8, M10 and M12. The nylon insert removes the need for a separate lock washer in suitable applications, which can help simplify fastening when working through maintenance jobs or small repairs. A 100 piece assortment also gives you a useful stock of everyday sizes for repeat use in the garage or workshop, while helping keep small fasteners organised and easier to find when needed.
