Pushnut Bolt Retainer 1/2-Inch by Hard-to-Find Fastener 25-Piece

Description

Product Overview

The 014973294793 Pushnut Bolt Retainer is engineered for precision and durability. Constructed from high‑grade alloy steel, each retainer nut is zinc plated to resist corrosion and extend service life. The 1/2‑inch diameter provides a standard fit for a wide range of fastener applications, while the 3.75‑inch length offers ample engagement depth for secure attachment. The round head style and smooth surface allow easy insertion and removal without damaging surrounding components.

Designed with a swage fastener type, the retainer nut locks in place by deforming slightly under torque, creating a permanent yet reliable connection. This mechanism eliminates the need for additional locking devices, simplifying assembly processes and reducing overall part count. The product is supplied in a box of 25 pieces, making it a cost‑effective solution for bulk projects and repeat‑order inventory.

All dimensions are measured in inches, ensuring compatibility with standard U.S. hardware specifications. The lightweight design, at just 0.32 ounces per piece, minimizes added weight while maintaining structural integrity. Whether used in industrial machinery, automotive systems, or home improvement tasks, the Pushnut Bolt Retainer delivers consistent performance across diverse environments.

Usage

These retainer nuts excel in applications where a secure, vibration‑resistant connection is required. In industrial settings, they are commonly employed to fasten panels, brackets, and housings on equipment that experiences frequent motion or thermal cycling. The zinc finish provides an extra layer of protection against moisture and chemical exposure, making the nuts suitable for outdoor installations and harsh chemical environments.

Automotive technicians appreciate the ease of installation, as the round head allows for quick hand‑tool engagement. The 1/2‑inch thread size aligns with many standard bolts and screws, facilitating seamless integration into existing assemblies. For DIY enthusiasts, the retainer nuts are perfect for building custom furniture, securing electrical enclosures, or reinforcing structural joints in home projects.

Because the retainer does not require additional locking components, it reduces the time spent on each assembly step. This efficiency translates into lower labor costs and faster turnaround for production lines. The product’s versatility also means it can be used by hobbyists, engineers, and maintenance crews alike, providing a universal solution for fastening challenges.

FAQ

What thread size does the retainer nut accept?

The retainer nut is designed for a #0 thread size with a 1/2‑inch inside diameter, matching common bolt specifications.

Is the zinc coating suitable for marine environments?

While the zinc finish offers good corrosion resistance, for prolonged exposure to saltwater we recommend additional protective measures such as sealants or marine‑grade coatings.

Can these nuts be reused after removal?

Because the swage mechanism deforms slightly to lock the nut in place, reuse is not recommended for critical applications. For non‑critical uses, they may be reinstalled, but performance cannot be guaranteed.

Do you offer larger quantity packs?

Yes, bulk packaging options are available. Contact our sales team for pricing and availability of larger volume orders.

What is the weight of each individual nut?

Each retainer nut weighs approximately 0.32 ounces, making them lightweight while still providing strong holding power.
