Metal Threaded Star Insert 10pcs for 3/4″ Tubing – JJHXSM Spring Steel

Description

Product Overview

The JJHXSM Metal Threaded Star Insert set offers ten precision‑engineered components designed specifically for 3/4″ round tubing applications. Each insert features a star‑shaped thread profile that engages firmly with the inner wall of the tube, creating a secure, load‑bearing connection that can withstand repeated assembly and disassembly cycles. Constructed from high‑grade spring steel, the inserts provide exceptional elasticity, allowing the star‑type clamp to flex during installation and then snap back to lock in place. A robust galvanized coating protects the steel from corrosion, ensuring long‑term performance even in humid or outdoor environments.

Technical specifications include a 1/4‑20 thread size, compatible with standard hardware such as machine screws, bolts, and set screws. The outer diameter of the target tubing is 3/4″, with a recommended wall thickness of 16‑18 gauge to achieve optimal bite depth. The package dimensions are compact at 4.09 x 2.36 x 0.59 inches, weighing just 3.17 ounces, making storage and handling effortless for both professional installers and DIY enthusiasts.

Usage

These star‑type threaded inserts excel in a variety of settings where a reliable, threaded connection is required without compromising the structural integrity of the tubing. In furniture manufacturing, they enable quick attachment of legs, brackets, and decorative hardware, allowing designers to create modular pieces that can be easily reconfigured or repaired. Fitness equipment manufacturers rely on the strong grip of the star insert to secure adjustable components such as weight plates, resistance bands, and frame connectors, ensuring safety during high‑intensity workouts.

Display equipment, including exhibition stands, signage frames, and lighting rigs, benefits from the insert’s ability to hold heavy fixtures while maintaining a clean aesthetic. Because the inserts are made from spring steel, they absorb minor vibrations and shocks, reducing the risk of loosening over time. Additionally, the galvanized surface provides resistance to rust, making these inserts suitable for outdoor installations such as garden furniture, patio structures, and temporary event constructions.

FAQ

What tubing wall thickness is recommended for these inserts?

The inserts perform best with tubing wall thicknesses between 16 and 18 gauge, providing enough material for the star clamp to bite securely without deforming the tube.

Can these inserts be used with materials other than steel tubing?

Yes, they are compatible with aluminum and PVC round tubing as long as the outer diameter is 3/4″ and the wall thickness meets the recommended range. However, the grip strength may vary slightly depending on material hardness.

How do I install the star‑type insert correctly?

First, clean the interior of the tube to remove debris. Insert the star‑type clamp from the entry end; the clamp will flex outward as it passes through the tube. Once it reaches the desired depth, the clamp snaps back, and the star teeth bite into the inner wall, creating a threaded anchor. Tighten a compatible 1/4‑20 screw to test the hold.

Is there a warranty on these inserts?

JJHXSM provides a one‑year limited warranty covering material defects and coating failures. If you encounter any issues within this period, contact our support team for a replacement or refund.

Do you offer bulk pricing for large orders?
