Core Advantages

• Segmented diagonal knurling: Multiple knurled bands along the body increase the contact area with the plastic and provide several engagement zones.
• Herringbone pattern: The angled knurl direction engages the plastic in both rotational and axial directions, supporting torque and pull-out resistance.
• Anti-pull-out geometry: The knurled sections create mechanical interlock with the plastic after molding or heat staking.
• Brass construction: Brass offers thermal conductivity and corrosion resistance in typical indoor environments, and is compatible with common molding and heat-staking processes.
• Cleaned surface: The cleaning treatment removes machining residue and prepares the surface for consistent insertion behavior.
• M5 internal thread: Suits fasteners used in medium-size housings and plastic parts.
• Customizable segment layout: The number and spacing of knurl segments can be adjusted to match specific boss designs.

Product Features

• Prototype and low-volume molded assemblies
• Thermoplastic parts requiring repeated fastening and disassembly

FAQ and Solutions

Q1: What is the purpose of the segmented herringbone knurling?
A: Multiple knurled segments provide several engagement zones within the plastic, and the angled knurl direction engages the material in both rotational and axial directions. This can improve torque and pull-out resistance compared with a single knurled band.

Q2: How is this insert installed?
A: It can be installed by insert molding, heat staking, ultrasonic insertion, or press-fit, depending on the plastic type and wall thickness. Heat staking is commonly used for thermoplastics because the melted plastic flows into the knurl and resets around it.

Q3: Can the outer diameter, length, or thread be customized?
A: Yes. Outer diameter, total length, thread size, knurl pattern, and segment layout can be produced to customer drawings or samples.

Q4: What information is needed for a custom quote?
A: Please provide outer diameter, total length, thread size, knurl type, segment layout, material, surface treatment, quantity, and any drawing or tolerance requirements.

Precautions

• Confirm the molded hole diameter and boss wall thickness before installation.
• Use installation parameters recommended for the specific plastic material.
• Avoid excessive heat during heat staking, which can deform the surrounding plastic.
• Store in a dry environment to limit surface oxidation.
• Verify thread compatibility with the mating screw before assembly.
• For high-torque applications, test the insert in the actual plastic to confirm performance.
