30 Pieces of M3 x 5.4mm H x 4.6mm OD Metric Brass Threaded Inserts

[Package Contents] - 30 Pieces x Heat-Sealed Flange Threaded Inserts. The threaded insert sets have the following dimensions: Thread Size: M3 x 0.5mm; Flange Outer Diameter: 5.5mm/0.22 inch; Overall Nut Size: 5.4x4.6mm / 0.21x0.18 inch (H*OD).
[Features] - Made of high-quality brass, these threaded insert nuts are corrosion-resistant, have excellent thermal conductivity, and are highly durable. They resist breakage and deformation, are strong and durable, do not rust, and can easily withstand the intense heat generated during plastic thermal forming processes.
[Function] - These natural brass threaded inserts are widely used in 3D printing, injection-molded plastic parts, automotive plastic housings, laptop cases, electronic products, PCB mounting, etc. They are commonly used threaded fasteners for thermoplastics (including PLA, PETG, ABS, PP, etc.) and are often used for 3D printing prototypes.
[Easy to Use] - These inserts come with a brass press tool with a soldering tip that allows you to easily press the insert into the 3D printed part using a soldering iron. You can use a regular soldering iron to heat it, then easily press it into the hole. Allow it to cool and solidify within the plastic material.
[Special Design] - These threaded inserts are precision machined; the external reverse spiral serrations significantly improve torque and tensile strength, ensuring a firm and stable connection to prevent loosening. The female thread is deep and clean, the force is evenly distributed, and the threaded connection is more secure.
