Stainless Steel SS304 Coiled Helical Thread Inserts M8 x 1.25 – 100pcs

Description

Product Overview

The FTVOGUE 100‑piece SS304 stainless steel helicoil set offers a premium solution for restoring stripped or damaged M8 screw holes. Each insert is fabricated from high‑grade SS304 coiled wire, providing exceptional corrosion resistance and tensile strength. The helical design mimics the original thread profile, ensuring a seamless fit that behaves like a factory‑installed thread. With a pitch of 1.25 mm and a length of 2 D, the inserts deliver optimal engagement depth while maintaining a low profile for compact assemblies. The package includes a full complement of 100 inserts, allowing for multiple repairs across a range of components, from automotive brackets to electronic enclosures. Dimensions of the individual inserts are engineered to meet industry standards, guaranteeing compatibility with standard M8 taps and tools. This product is ideal for technicians, maintenance engineers, and hobbyists seeking a reliable, repeatable method to extend the service life of their equipment.

Usage

These helicoil inserts excel in environments where frequent disassembly is required, such as machinery that undergoes regular maintenance, aerospace components subject to vibration, and consumer electronics that need periodic upgrades. The stainless steel construction tolerates exposure to moisture, chemicals, and temperature fluctuations, making it suitable for outdoor applications, marine equipment, and industrial machinery. Installation is straightforward: drill the damaged hole to the recommended size, tap the hole with an M8 × 1.25 tap, and use the supplied installation tool to press the helicoil into place. Once seated, the repaired thread can accept standard M8 bolts with the same torque specifications as the original design. This versatility means the inserts can be employed in low‑strength alloys, plastics, and even soft metals where traditional thread repair methods might cause further damage.

FAQ

Can these inserts be used in plastic components?

Yes, the helicoil design is well‑suited for low‑strength materials such as plastics. The coiled wire distributes load, preventing the plastic from cracking while providing a strong, reusable thread.

What tap size should I use before installing the helicoil?

Use an M8 × 1.25 tap that matches the insert’s pitch. The tap creates the proper internal profile for the helicoil to seat securely.

Is any special tool required for installation?

A standard helicoil installation tool is recommended. It aligns the insert and applies even pressure, ensuring the helicoil is fully seated without damaging the surrounding material.

How many times can a repaired thread be reused?

When installed correctly, the helicoil can withstand thousands of fastening cycles, far exceeding the lifespan of a typical repaired thread in comparable materials.

What warranty does FTVOGUE provide?

FTVOGUE offers a one‑year limited warranty covering material defects and manufacturing errors. Contact our support team for assistance with any issues.
