MP015406

Achieve strong, reliable threading in plastic components with this MP015406 100-pack of M4 Press-In Thru Threaded Brass Inserts. Made from durable brass and treated with a passivated finish, these inserts provide excellent corrosion resistance and long-term mechanical strength. Designed for lightweight designs, these inserts are a lead-free alternative to stainless steel, making them ideal for environmentally responsible and RoHS-compliant applications. The blind-end design effectively prevents plastic intrusion into the threads during installation, ensuring clean, precise fastening every time.

• Offers excellent durability, thermal conductivity, and resistance to wear and deformation.
• A safe, RoHS-compliant alternative to stainless steel — ideal for sustainable manufacturing.
• Improves surface corrosion resistance for longer service life, even in harsh environments.
• Prevents plastic flow into threads during installation, preserving internal thread integrity.
• Allows bolts or screws to pass completely through when needed — suitable for multi-part assemblies.
• Perfect for use in plastics where minimizing weight while maximizing fastening strength is key.
• Simple post-mould insertion process — no need for heat or ultrasonic welding.
• Ideal for plastic enclosures, electronics, consumer devices, 3D printed parts, and light industrial components.
