JX-21JG269-M5-13.6-D7.13-SS, stainless steel Heat-Set Inserts for Plastic

Deformed threads create prevailing torque locking features to prevent screw loosening due to vibration.

Blind-end protects the threads from plastic intrusion.

Stainless steel inserts offer a lead-free alternative. Features of knurled nuts

Knurled nuts use the embossing wheel to emboss the mesh pattern (knurled mesh pattern), and the middle is slotted. The threads are still guaranteed to be 6H accurate after milling the grooves. This knurled brass nut is used in power tools, unlike other knurled brass nuts, the diamond pattern of this knurled brass nut is located in the middle section of the product, and the diamond pattern knurling wheel rolls out the diamond pattern along the large outer step surface. Knurled nut features are as follows:

1. A design that allows for less flesh thickness.

2. Can be buried quickly by using hot melt or ultrasonic.

3. Round head guide design, good positioning effect; not easy to be skewed.

4. Staged outer diameter design, progressive into the plastic; mother material plastic is not easy to burst.

5. Double bevel pattern design in the opposite direction, combined with plastic precision, strong twisting, and pulling force.

Application of knurled nuts

Knurled nuts are more widely used in cell phones, portable computers, a variety of plastic housings, communications, micro-motors, computers, electrical appliances, electronics, toys, clocks and watches, lighting, locomotives, and other industries.

Stainless Steel General Characteristics: Designed for machining, non-magnetic

Common Applications: Electronic hardware, automotive, aerospace, medical instruments, and many applications requiring corrosion resistance

Tolerances for 1/2" Dia: Cold finished+/- .002.Install these inserts into plastic parts to create a secure base for fasteners. Also known as Chevron and headed inserts, they are often used to strengthen mounting holes on brittle plastics, such as on 3D-printed parts. Unlike plastic threads, which wear down with repeated use, these threads hold their shape over a long life. Press inserts into square holes that have been drilled, printed, or molded into plastic parts, then heat them with a soldering tip to melt the surrounding plastic. As the plastic cools, it fuses to the sharp, diagonal ridges around the inserts, which withstand torque and prevent the inserts from being pulled out. The interior is fully threaded, so you can access the threads from both sides of a through-hole.

Flanged inserts have a wider end than standard inserts, which gives them a larger load-bearing surface and makes them harder to pull out. The flange also gives you a larger contact area for soldering. When threading into the flanged side, these inserts prevent over-tightening, which can cause brittle plastic to crack.

Made with lead, brass inserts are stronger than aluminum and other brass alloys but not as strong as stainless steel inserts. They have good corrosion resistance.

Aluminum inserts are 70% lighter than brass and stainless steel inserts, have good corrosion resistance, and are lead-free. Since they’re lead-free, they can be safely recycled.

Stainless steel inserts are stronger than brass and aluminum inserts, have excellent corrosion resistance, and are lead-free. Since they’re lead-free, they can be safely recycled.
