Good Value

Solid nuts for the price. The plastic case latch broke after a month, but the hardware is great.

Great Variety Pack

Having all these sizes in one box saves so much time. The washers are a nice addition.

Perfect for Automotive Work

I use these for non-critical engine bay components. They hold up well against vibration.

Excellent Quality Fasteners

Used these for a machinery repair project. The grade 8.8 strength is genuine and none of the nuts stripped during tightening.
