5/16-18×0.625 304 Stainless Steel Helical Coil Insert uxcell 25pcs

Description

Product Overview

The uxcell 5/16-18×0.625 304 stainless steel helical coil thread insert is engineered to provide a reliable, long‑lasting repair for damaged or stripped threads in a variety of applications. Constructed from premium 304 stainless steel, the insert offers excellent corrosion resistance, making it suitable for environments exposed to moisture, chemicals, or high temperatures. Each coil is precisely formed to a 0.625‑inch installed length, allowing it to fit within limited space while delivering a strong, permanent thread that matches the original specifications. The product comes in a convenient pack of 25 pieces, ensuring you have enough inserts for multiple repairs or large‑scale projects. Its silver‑tone finish not only adds a professional appearance but also helps identify the component quickly during installation.

Usage

These helical coil inserts are ideal for restoring threads in industrial machinery, electronic housings, lighting fixtures, radiators, and even 3D‑printed components where traditional repair methods may be impractical. To install, simply drill a hole to the specified diameter, tap the hole if necessary, and press the coil into place using a suitable installation tool. The insert expands slightly as it is driven in, creating a tight, secure fit that resists loosening under vibration or load. Because the material is 304 stainless steel, the repaired threads can withstand repeated assembly and disassembly without degrading, making them perfect for maintenance cycles in factories, workshops, or field service environments. Whether you are a professional technician, a hobbyist maker, or a DIY enthusiast, these inserts provide a straightforward solution to extend the life of your equipment.

FAQ

What size hole should I drill for this insert?

For the 5/16‑18×0.625 insert, drill a hole with a diameter of 9.8 mm (0.39 in). This size allows the coil to expand properly and create a secure thread when installed.

Can I use these inserts in plastic components?

Yes, the helical coil design works well in both metal and high‑strength plastic substrates. Ensure the drilled hole is clean and free of debris to achieve the best grip.

How many inserts are included in the package?

The package contains 25 individual helical coil inserts, providing ample quantity for multiple repairs or large‑scale maintenance projects.

Are the inserts reusable after removal?

While the inserts are designed for permanent installation, they can be removed with a proper extraction tool. However, reuse may reduce their holding strength, so it is recommended to replace them if a reliable repair is required.

What is the difference between this insert and a standard threaded insert?

Our helical coil insert expands as it is pressed into the hole, creating a self‑locking thread that resists loosening under vibration. Standard inserts often rely on external fasteners or adhesives, which may not provide the same level of durability in demanding environments.
