JX-21JG105-M3-H6-SS, Brass Unthreaded Inserts for Plastic, Surface treatment electroplating environmental protection nickel

Name: Brass Unthreaded Inserts for Plastic

Material: Brass, Brass or brass alloy: H63;H65;H68;H70;H90, Stainless steel, Steel

Made from brass, these inserts are nonmagnetic, mildly corrosion-resistant, and electrically conductive. Also known as compression limiters, they keep screws securely installed even if the surrounding plastic expands or shrinks when the screw is tightened. Various specifications can be produced according to drawings or samples.n For thermoset and thermoplastic components

1. Fast installation without a special tool

2. High-strength threads in through holes

3. Screw-locking

The insert nut knurled with a retaining flange is pressed into the rear of the through-hole (accessibility from two sides) until the retaining flange touches the component. The slotted anchoring section with diamond knurl is compressed. When the screw is screwed in, the thread insert is forced open in the anchoring section so that the diamond knurl penetrates the plastic material. The retaining flange which acts as shoulder support ensures a good locking effect against pull-out due to additional positive locking. In addition, the screw is locked. For the additional expansion force, the tightening torque must be increased by 10 %. Material: brass CuZn38Pb2 (compliant with EU 2000/53) / brass CuZn39Pb3.

Characteristics of  Inserts for Plastic Nuts: 

1. Allows for designs with less material thickness.

2. Can be quickly embedded using methods such as heat fusion or ultrasonic technology.

3. Designed with a round head for excellent positioning and minimal deviation.

4. Features a stepped outer diameter design for progressive plastic injection, reducing the risk of material cracking.

The double helix knurling design in opposite directions provides a strong torsion force when combined with plastic, ensuring a precise connection.

Inserts for Plastic nuts are widely used in various industries such as mobile phones, laptops, plastic casings, telecommunications, micro motors, computers, appliances, electronics, toys, clocks, lighting fixtures, motorcycles, automobiles, rail transportation equipment, catering equipment, medical devices, and more.
