Core Advantages

• Surface flange: The flange provides a bearing surface against the plastic, distributes load at the contact face, and limits insertion depth during installation.
• Diagonal knurling: The angled knurl pattern engages the thermoplastic in both rotational and axial directions, supporting torque and pull-out resistance.
• Anti-pull-out geometry: The knurled body creates 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 structural plastic parts.
• Customizable flange: Flange diameter and thickness can be adjusted to match specific boss designs.

Product Features

• Surface flange at the top, with diagonal knurling along the insert body.
• Flange profile for seating against the plastic surface and limiting insertion depth.
• Machined brass body with consistent dimensional tolerance.
• Internal M5 metric thread produced to standard pitch.
• Outer diameter of 10.0 mm and total length of 6 mm.
• Surface cleaning treatment for removal of cutting fluid and fine particles.
• Suitable for insert molding, heat staking, ultrasonic insertion, and press-fit.
• Can be produced to customer drawings for non-standard dimensions and flange geometry.

Applications

• Consumer electronics housings and enclosures
• Home appliance plastic components
• Automotive interior plastic components
• Industrial control panels and instrument casings
• Power tool and equipment housings
• Telecommunications equipment
• Prototype and low-volume molded assemblies
• Thermoplastic parts requiring repeated fastening and disassembly

FAQ and Solutions

Q1: What is the function of the surface flange?

A: The flange provides a bearing surface against the plastic and limits how far the insert can be pressed or heat-staked into the hole. It also distributes load at the contact face during tightening.

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, flange dimensions, and knurl pattern 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, flange diameter and thickness, knurl type, material, surface treatment, quantity, and any drawing or tolerance requirements.

Precautions

• Confirm the molded hole diameter, flange dimensions, 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.
