[initeq] M3-0.5 Threaded Heat Set Inserts for 3D Printing (100, Short)

Q: What size hole do these need for best strength (width in mm?)

This will depend somewhat on your printer settings and material properties, but a hole tapering from 5.23mm to 5.05mm diameter, depth 3.89mm should be a very good starting point.

Q: What is the best hole size to get good retention?

On my prints, I have been using 5.60 mm (0.220 inches). with 1.50 inch depth for the short inserts and 0.250 inches for the longer inserts. It has worked quite well- easy to place the insert on top and sinks down in 1-2 seconds with a soldering iron. Depending on your screw/bolt length, you might consider add a deeper, smaller hole below the insert so the screw doesn't bottom out.

Q: What is the length of this product? i am looking for m3 x 0.50 mm thread size, 3.800 mm installed length

Please see the dimensions on the drawing (one of the product images). OAL is 3.81mm

Q: How long is this produsct from top to bottom? i'm hoping for m3 x 0.50 mm thread size, 3.800 mm installed length

The pieces that I reveived are 3.85mm, 0.1515" +/- a few thousands.
