Usage and install: pre-drill a proper hole, screw in with internal hex tool; Unique self-tapping designed external thread, contribute to tapping, with good tensile resistance, install with hex key, tapered external threads makes it not easy to pull out caused by vibration

Good Performance: these M3 brass nuts can be widely used in 3D printing injection molding to achieve tight fixation. Heat set Inserts can be installed by ultrasonic or heat into thread tapered hole, or molded in during injection. Just using tools such as a soldering iron or screws, you could easily set brass embedment screws into 3D printed holes.

Premium craftsmanship: the M3 brass nuts are manufactured with high-quality craftsmanship to ensure that all nuts have uniform and fixed standard round and twill thread knurl. The diameter of the front end of the nut is slightly smaller, so that you can easily align the nut in the reserved 3D printing hole. Compared with the ordinary straight-grain knurl, the twill thread knurlhas better pull-out and torque resistance, so that it will not shake and is easy to fix.

Durable material: all nuts are made of high-quality brass, which can prevent rust and oxidation, high temperature resistance, corrosion resistance, not easy to deform and have good thermal conductivity, which makes the nuts can be heated quickly and easily inserted so as to greatly shorten your work time.

√ Quantity: VIGRUE this nuts kit includes 340pcs of M2 M2.5 M3 M4 M5 M6 Thread Knurled Nuts, and it includes 12 various common sizes knurled nuts, sufficient for daily application.

√ Great Performance: Thanks to the outside oblique threads, it holds firmly in the pressure part and ensuring a high balanced tightening, once heated plastic around the brass sleeve nuts cools and hardens, the threaded nuts are firmly anchored

√ Organized Box: The nuts come in a portable clear box with corresponding sizes label. It is convenient for you to put away and store, which allow you to get the one you need quickly, improving your project efficiently.

Package Content: You will get 100pcs 3D printing brass nuts, super large quantity can meet your needs of connecting numerous 3D printing accessories. Each knurled brass nut measures about M3x4x5mm / M3x0.16x0.2inch, please ensure that the size of the nuts can well match your 3D printer.

Premium Material: The threaded inserts for 3D printing are made of high quality brass, extremely sturdy, not easy to break or deform, also can withstand high temperature above 300°C / 572°F. Excellent thermal conductivity also makes your 3D printer to work more effectively.

Easy to Install: The knurled brass nuts can be easily installed into the the tapered holes of 3D printers by heating, also can be molded by injection molding. The 3D printing brass nuts with full knurled patterns can perfectly match with your 3D printers. Practical nuts make your 3D printer work well.

T-NUTS ARE A PRESS-IN TYPE OF THREADED INSERT - EASLY INSTALLED WITH A HAMMER.

USED WITH SOFT MATERIALS SUCH AS WOOD OR PLASTIC.

HAS SHARP PRONGS UNDER THE FLANGE THAT DIG INTO THE MATERIAL LIKE A NAIL.

M3 THREAD INSERTS FOR YOUR 3D PRINTED PARTS: The ruthex threaded nuts can be retrofitted by heat or ultrasound into parts of 3D printers from e.g. Anycubic or Prusa. With the help of heat from a soldering iron or ultrasonic, the insert nuts are simply embedded in a blind- or through hole

FIXED HOLD WITH EASY APPLICATION: Thanks to the geometry of the threaded sleeve, the threaded sleeve holds it firmly in the pressure part. The opposing spiral-shaped knurled nuts ensure a balanced high tightening and loosening torque, as well as a high tightening force. The guide has made insertion much easier

STABLE & LONG-LASTING THREAD INSERTS: The inserts with internal thread brass, which ensures optimum corrosion resistance and thermal conductivity. This means that each insert nut can be used for a long time and is easy to use.
