## Description

Specification： Product Name: Knurled Nut Application: Heat resistant, great for 3d printing Material: Brass Main Color: Brass Tone Inner Hole Diameter: M1.6 (1.6mm) Height: 4mm/0.16" Outer Diameter:2.5mm/0.1" Weight: 6g Package Content: 50pcs x Knurl Thread Inserts Nuts Note: 1)The colors may have difference as the different display, please understand. 2)Please allow 1-2mm error due to manual measurement, please make sure you do not mind before you bid.

Review: They are not 5mm OD inserts. Dissappointing and a massive waste of time for me. - First and foremost, I received these and really felt confused why all my components I spent over 13 hours weren't properly accepting these inserts. I thought I was an idiot and didn't measure correctly, but all threaded inserts that I've seen actually measure the outer diameter with the knurls included. Search "M3 inserts" and look at the in-saiL brand that show the CAD file for their inserts. The OD is measured from the widest points. Other sellers that are selling these exact same inserts like uxcell list the OD as 5.4mm, but you really just have to include a diagram in the store page. Put the CAD drawing in there. I did count 50 inserts, the quality seems okay but one insert I saw did not have a chamfer on the opening so it's not perfect, and I think I prefer the counter-rotating knurled inserts over these vertical ones.
Review: Incorrect size - The outer Diameter of the threaded inserts is actually 5.4 mm, not 5 mm!!
