About this item

  • [SIZE] - Thread Dia: M3; Pitch: 0.5mm; Overall Size: 5mm x 4mm / 0.20" x 0.16"(OD*L)
  • [MATERIAL] - Made of brass material, high hardness and durable. Provides good mechanical properties with increased corrosion and heat resistance
  • [FEATURE] - The embedding nut has a guide so there is no need for a counterbore or countersink. Smooth surface, firm and uniform, easy to install.
  • [ADVANTAGE] - Due to the embossing process on the outer diameter of the insert, it forms certain friction and bites force with the brass insert after forming, which can be fixed on the inside so that it will not fall off easily. Has a certain torsion and tension.
  • [APPLICATION] - Can be installed by ultrasonic or heat into the plastic matrix, or formed during the injection, widely used in 3D printing injection molding to achieve tight fixation.

I use Uxcell brass inserts for all my 3d printed projects with more than one part. These inserts work very well and are easy to insert with a soldering. I do recommend getting a soldering iron brass adapter to use when inserting. These inserts take your 3D printed projects up another level. I know there are cheaper inserts, but these work so well, I'm not going to waste my time looking for an alternative.

Needed to make a new frame for my AnyCubic resin printer because they discontinued the product and the 3 party replacements are overpriced, or wrong size entirely. These are quality, no burs, clean threads and most importantly the correct size.

I nearly replaced the entire vat because resin had worked its way into the threads of the screws and hardened - making it impossible to remove the screws without an extractor. Needless to say some of the anchors had to be replaced afterward. I used a soldering iron to carefully heat the old anchors and then pried them out - then used the iron to push these in. These are seemingly an exact match for the anchors that were already installed in the tank, so they worked perfectly.

This was my first order of the threaded inserts and the quality is fantastic. Will likely need inserts in the future and will order again.

Not sure how you could knock these in any way. Matches description 100%. If you've never worked with these, they're great. Very satisfying to install. If you have a problem with these, you're likely doing something wrong.

they don't twist out or pull out, so long as you don't over tighten them you can pull on it with 100 lbs

These work well as basin/sink anchors when epoxied into the underside of a counter top.

None of them was mishaped like some others I received. Good quality, precise threads.

Not much to say about them, they're accurately threaded, and are exactly as described
