Midwest Fasteners 08205 1/4-20 Grade 8 Nylon Insert Lock Nut

Midwest Fasteners 08205 1/4-20 Grade 8 Nylon Insert Lock Nut

The Midwest Fasteners 08205 is a 1/4-20 Grade 8 nylon insert lock nut built from steel with a yellow zinc finish for added corrosion resistance. The nylon collar grips the mating bolt threads to resist loosening from vibration, making this nut a reliable choice anywhere a standard hex nut would back off over time. Sold Each, it is sized to match standard 1/4-20 coarse thread fasteners and is rated Grade 8 for use on higher-strength assemblies.
