uxcell #8-32×0.328 304 Stainless Steel Helical Coil Wire Thread Insert 25pcs

Description

Product Overview

The uxcell #8-32×0.328 helical coil thread insert is engineered from premium 304 stainless steel, delivering exceptional corrosion resistance and long‑term durability in demanding environments. Each insert features a precise 0.328‑inch (8‑32) inner thread that mates seamlessly with standard machine screws, while the outer diameter of 5.3 mm (0.21 in) provides a robust engagement with the host material. The coil design creates a self‑tapping, reinforcing thread that distributes load evenly, reducing stress concentrations and preventing material stripping. Packaged in a convenient 25‑piece box, this product offers a ready supply for batch production, maintenance inventories, or hobbyist projects. The inserts are pre‑finished with a smooth, polished surface that minimizes friction during installation, ensuring a consistent and repeatable fit across a wide range of substrates, including aluminum, steel, and high‑strength plastics.

Usage

Designed for versatility, these helical coil inserts excel in applications where a strong, permanent thread is required but the base material cannot accommodate traditional tapping. Common use cases include automotive engine components, electronic enclosures, aerospace brackets, and consumer appliance housings. The insert’s 2‑D installed length provides sufficient thread engagement for high‑torque fastening, making it ideal for securing circuit board mounts, motor housings, and structural panels. Installation is straightforward: drill a pilot hole to the specified diameter, tap the hole with a standard 8‑32 tap, and screw the insert in using a compatible driver. The self‑locking nature of the coil ensures the insert remains firmly seated even under vibration or thermal cycling, delivering reliable performance in both static and dynamic conditions.

FAQ

What materials can these inserts be used with?

They are compatible with a wide range of metals such as aluminum, steel, and brass, as well as high‑strength engineering plastics like polycarbonate and nylon.

Do I need special tools to install the inserts?

No special tools are required. A standard 8‑32 tap and a screwdriver or hex driver that matches the insert’s outer diameter are sufficient for installation.

How does the coil design improve thread strength?

The helical coil expands the thread engagement area, distributing load across a larger surface and reducing the risk of thread stripping or material fatigue.

Are these inserts suitable for high‑temperature applications?

Yes, 304 stainless steel maintains its mechanical properties up to 870 °C (1600 °F), making the inserts suitable for many high‑temperature environments.

Can I reuse the inserts after removal?

While the inserts are designed for permanent installation, they can be removed with care using a suitable extractor. Re‑installation is possible if the original hole remains undamaged.
