3/8″ Push on Pushnut Caps by TAHULIK – Spring Steel, 6‑Piece Set

Description

Product Overview

The TAHULIK 3/8″ push‑on pushnut caps are precision‑engineered components designed to replace traditional split pins and provide a permanent, secure fastening solution for a wide range of industrial and consumer equipment. Each cap is fabricated from high‑grade spring steel that has been zinc‑plated to resist corrosion, ensuring long‑term durability even in harsh outdoor environments. The caps measure 0.8 x 0.8 x 0.34 inches and weigh just 0.93 ounces, making them lightweight yet robust. The internal flange design creates a tight interference fit on 3/8‑inch shafts, eliminating any play and reducing vibration that can lead to premature wear. The package includes six caps, offering enough inventory for multiple repairs or for stocking spare parts in a maintenance workshop.

Usage

These pushnut caps are ideal for a variety of applications where a reliable, permanent connection is required without the need for drilling or welding. Common uses include hand trucks, push wagons, rolling bins, lawn mower decks, pressure washer frames, and any equipment that utilizes a 3/8‑inch axle or shaft. The caps can be quickly installed by aligning the flange with the shaft end and delivering a firm tap with a hammer; the spring steel flexes slightly to lock in place, providing a secure fit that resists loosening under vibration or load. Because the caps are permanent, they are especially suited for high‑frequency use environments such as warehouse logistics, landscaping services, and outdoor recreation equipment maintenance.

FAQ

Can these caps be used on shafts larger than 3/8 inch?

No. The internal flange is sized specifically for 3/8‑inch shafts. Using them on larger diameters may result in an insecure fit and could cause damage to the equipment.

Do I need any special tools to install the caps?

Only a standard hammer is required. Align the cap with the shaft end and tap firmly until the cap seats securely. No additional tools or fasteners are needed.

Are the caps reusable if I need to replace them?

The caps are designed as permanent fasteners. While they can be removed with a pry tool, re‑installation is not recommended because the interference fit may be compromised.

What warranty does TAHULIK provide for these caps?

TAHULIK offers a one‑year limited warranty covering manufacturing defects. If you encounter any issues, contact our support team for a replacement or refund.

How do these caps compare to traditional split pins?

Compared to soft‑metal split pins, the spring‑steel pushnut caps provide greater tensile strength, superior vibration resistance, and a permanent connection that does not require periodic tightening.
