Au-ve-co Products 8665 Push Nut Zinc-plated 1/2 in

Product Description

The AU-VE-CO PRODUCTS 8665 is a zinc-plated push nut designed for use with non-threaded fasteners on 1/2-inch diameter shafts. Push nuts seat by pressing onto a shaft, creating a secure, vibration-resistant hold without threads, clips, or additional hardware. The zinc plating provides corrosion resistance suitable for light-duty indoor and covered mechanical applications. At 0.01 pounds, this fastener is a small but essential hardware component used across HVAC, plumbing, and general mechanical assembly work wherever a quick, reliable shaft retention solution is needed.

This push nut is used in a wide range of trade and light industrial applications where non-threaded shaft retention is required. Common install scenarios include securing blower wheel hubs, motor shaft components, linkage assemblies, and similar light-load mechanical connections in HVAC equipment and plumbing fixture assemblies. The 1/2-inch shaft diameter fit makes it a standard size found in residential and light commercial mechanical systems. Technicians often keep this fastener on hand as a replacement item during service calls.

Key Features

• Zinc-plated finish for corrosion resistance in covered mechanical environments
• Designed for 1/2-inch diameter non-threaded shafts
• Press-on installation requires no threading or special tools
• Lightweight at 0.01 pounds - minimal added load to shaft assemblies
• Suitable for use as a replacement retention fastener during field service

Compatibility

Designed for use with non-threaded fasteners on shafts with a 1/2-inch diameter. Suitable as a general-purpose push nut replacement in HVAC, plumbing, and light mechanical assemblies requiring shaft retention without threads.

Installation Notes

Push nuts are typically installed by HVAC technicians, plumbers, or general mechanical tradespeople using hand pressure or a flat-faced press tool aligned squarely with the shaft end. Power down or de-energize any equipment and relieve system pressure before servicing shaft assemblies. Do not reuse a push nut that has been removed, as the retention tabs may be deformed and will not hold reliably on reinstallation.
