Prime-Line 9078488 Axle Hat Push Nuts 1/4 in Zinc 100 Pack

Product identity

The Prime-Line 9078488 Axle Hat Push Nuts are 1/4 inch zinc-plated steel fasteners supplied in a 100-piece pack. They are designed for maintenance technicians and equipment owners who need to secure wheels or rotating components on light-duty machinery. The push-on design suits quick field repairs on hand trucks, dollies, pressure washers and air compressors.

Installation limits

Each nut installs by tapping gently into place with a hammer or mallet, relying on inward-facing contact points that bite the shaft. Because the nuts are not threaded, they cannot be adjusted or torqued to a precise preload. They are unsuitable for applications that require a removable, reusable or high-tension fastener, and they will not hold on shafts that are undersized, oversized or heavily corroded.

Capacity and headroom

The 100-count pack provides ample supply for fleets of carts or multiple service calls, reducing re-order frequency. The zinc plating offers basic corrosion resistance for indoor or sheltered outdoor use, but it is not a substitute for stainless or coated hardware in continuous wet or chemical exposure. The 1/4 inch bore fits only shafts of that nominal diameter; larger axles will require a different size.
