Core Advantages

• Hexagonal body: The hex profile allows the nut to be held with a standard wrench during installation and supports resistance to rotation in the plastic after molding or pressing.
• Double-end internal thread: Internal threads at both ends allow fasteners to be inserted from either side of the insert, which suits through-connection layouts in plastic parts.
• Iron construction: Iron provides mechanical strength for applications subject to tightening torque and load.
• Electroplating option: The surface can be electroplated to provide corrosion protection where required by the operating environment.
• Precision machining: The machining process holds consistent dimensional tolerance on hex size, length, and thread.
• Two length options: The 12.5 mm and 9.5 mm lengths cover different boss depths and spacing requirements.
• M5 internal thread: Suits fasteners used in medium-size housings and plastic parts.

• Prototype and low-volume molded assemblies
• Thermoplastic parts requiring fastening from both sides

FAQ and Solutions

Q1: What is the purpose of the double-end internal thread?
A: Internal threads at both ends allow fasteners to be inserted from either side of the insert. This suits through-connection layouts where components are fixed on both faces of a plastic part.

Q2: How is this insert installed?
A: It can be installed by insert molding, heat staking, press-fit, or ultrasonic insertion, depending on the plastic type and wall thickness. The hex body allows the nut to be held with a wrench during installation.

Q3: Which length should be selected?
A: The 9.5 mm length suits shallower bosses and compact assemblies, while the 12.5 mm length suits deeper bosses and provides additional thread engagement and spacing. Selection depends on the boss depth and the required thread depth at each end.

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

Precautions

• Confirm the molded hole diameter, hex size, 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.
• Avoid excessive tightening torque, which can damage the internal thread or the plastic boss.
• Store in a dry environment to limit surface oxidation when the insert is supplied without plating.
• Verify thread compatibility at both ends with the mating screws before assembly.

Customization and Ordering

Non-standard embedded nuts can be produced according to customer drawings or samples. Customization options include hex size, length, thread size, thread configuration, material, surface treatment, and chamfer. Please contact us with your specifications and application details for a quotation.
