60 Pcs Wire Thread Inserts kit, M3 M4 M5 M6 M8 M10 Stainless Steel Wire Screw Sleeve Thread Repair Kit for Helical Repair, Eliminate Screw Hole Deviation

Description

Product Overview

The Ejoyous 60‑piece wire thread insert kit is engineered for precision repair of damaged or stripped screw holes across a wide range of industrial applications. Constructed from high‑grade stainless steel, each helicoil offers exceptional hardness, corrosion resistance, and wear durability, ensuring a long‑lasting threaded interface. The kit includes 10 pieces each of M3, M4, M5, M6, and M8 inserts, as well as 5 pieces each of M10 and a set of installation tools, providing a complete solution for thread restoration without increasing the original hole diameter. Detailed specifications such as item weight (3.67 oz), dimensions (2.76 × 1.97 × 0.39 in), and compatibility with standard metric threads are listed to help engineers select the right size quickly.

Usage

These wire thread inserts are ideal for maintenance technicians, machinists, and field engineers who need reliable thread repair in demanding environments. Whether you are servicing automotive engines, aerospace components, turbine assemblies, or heavy‑duty machinery, the kit’s anti‑loose locking design secures fasteners against vibration, shock, and repeated disassembly. Installation requires only a simple tap and insertion process: drill the damaged hole to the recommended size, tap the thread using the supplied tap set, and press the helicoil into place with the insertion tool. The result is a restored thread that matches original specifications, allowing original fasteners to be reused without compromising structural integrity.

FAQ

What sizes are included in the kit?

The kit contains ten pieces each of M3, M4, M5, M6, and M8 inserts, and five pieces each of M10 inserts, providing a total of 60 helicoils ready for a broad range of metric thread repairs.

Can the inserts be used on non‑metallic substrates?

While the helicoils are optimized for metal applications, they can also be employed on hardened plastics or composite materials when the substrate can accommodate the required tap depth and provides sufficient support for the inserted thread.

How does the anti‑loose feature work?

The locking mechanism is achieved by a slight deformation of the helicoil’s outer coil during installation, creating a compressive force that grips the surrounding material. This prevents the fastener from backing out under dynamic loads or repeated tightening cycles.

Is special equipment needed for installation?

No additional equipment is required beyond the taps and insertion tool included in the kit. The process follows standard helicoil installation procedures: drill, tap, insert, and snap the excess coil.

What warranty does Ejoyous provide?

Ejoyous offers a one‑year limited warranty covering material defects and manufacturing errors. Our support team is available to assist with any installation questions or concerns throughout the warranty period.
