【SPECIFICATION】These knurled threaded insert nuts are made of durable brass. High strength without deformation, abrasion and corrosion resistance. This set includes 305 sets of knurled nuts with 14 specifications and 6 apertures (M2, M2.5, M3, M4, M5, M6), the set included: M2*2.5*3.2--30PCS, M2*3*3.2--30PCS, M2*4*3.2--30PCS, M2.5*4*3.5--30PCS, M2.5*5*3.5--30PCS, M3*4*5--25PCS, M3*5*5--25PCS, M3*6*5--25PCS, M4*4*6--15PCS, M4*6*6--15PC, M4*8*6--15PC, M5*6*7--10PC, M5*10*7--10PC, M6*8*8---15PC.
【PREMIUM QUALITY】The thread brass knurled threaded insert embedment nuts is made of refined brass, which has high strength, wear resistance, corrosion resistance, not easy to deform, good thermal conductivity, and is beautiful and practical. Good thermal conductivity enables nuts to be quickly and easily heated for insertion, improving work efficiency.
【STRANDARD AND COMPLETE THREAD】Deep thread, neat and clean, not easy to strip during rotation, stable and reliable. Convenient operation, good texture, greatly improve your work efficiency.
【WIDELY USE】These heatset inserts can be widely used on the injection moulding for tightly fixing. Can be installed by ultrasonic or heat into thread tapered hole, or molded in during injection. Also apply to circuit board assembly and in the field of electronics. The plastic is formed around the brass insert. It would be better to put something in the threads to keep plastic from melting into the center. Using a normal soldering iron, you could easily set them into 3D printed holes.
【HIGH PRECISION】 The surface of the nut is flat and smooth without burrs, with high-precision internal and external threads, high fastening strength, and external twill knurling that is easy to insert into the hole and remain in place, improving work efficiency.
