What It Is
This pack contains eight zinc-plated steel push nuts sized at 5/8 inch. They are designed for automotive and general hardware tasks where a threaded fastener is not required. The flanged teeth grip a smooth shaft when pressed or lightly tapped into position. Builders and mechanics can use them for quick, permanent retention.
Installation Limits
A push nut relies on inward-facing flanges rather than threads, so it cannot be adjusted or reused once seated. Removal requires cutting the nut off the shaft, which destroys the fastener. The zinc plating provides basic corrosion resistance but is not intended for prolonged exposure to harsh chemicals or marine environments. Alignment must be correct before the final tap.
Upgrade Context
These replace makeshift solutions such as cotter pins, E-clips or improvised washers that can loosen under vibration. The jump is worth it when a low-profile, tool-free fit is needed on a plain shaft and the assembly will not require future disassembly. They are not suited for applications that demand a threaded connection or repeated servicing.

Questions about this item
Which pack size should I choose for a job needing several push nuts?
The 8-pack supplies eight identical 5/8" zinc-plated steel washer cap push nuts, enough for multiple fastening points.
How does the push-nut design hold a panel once installed?
Inward-facing flanges act as teeth that grip the shaft when the nut is pushed or lightly tapped on, resisting pull-out without threads.
What shaft diameter does the 5/8" size fit?
The 5/8" designation matches a 5/8 inch shaft, so the push nut seats on that diameter and the zinc-plated steel washer cap distributes the load.
