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. ## Features - 50pcs M1.6 knurled thread inserts nuts assortment kit. - Internal Thread Diameter: 1.6mm / 0.06"; Outer Diameter: 2.5mm /0.1"; Total Height: 4mm / 0.16" - Made of brass material, high hardness, rust resistance, easy to conduct heat, heat resistance and durable to use. - No need to counterbore or countersink the boss hole since the insert has guide pilot. - Widely used on injection molding for fastening. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07TTQXVQH | | Best Sellers Rank | 804,174 in DIY & Tools ( See Top 100 in DIY & Tools ) 1,006 in Nut Inserts | | Brand Name | Antrader | | Colour | Brass Tone | | Compatible Groove Diameter | 1.6 Millimeters | | Customer Reviews | 4.5 out of 5 stars 44 Reviews | | Drive Style | Spline | | Exterior Finish | Brass | | Exterior finish | Brass | | Fastener Type | Knurled | | Fastener type | Knurled | | Finish Types | Brass | | Inside Thread Size | M1.6 | | Item Diameter | 1.6 Millimetres | | Item Dimensions | 4 x 2 x 4 millimetres | | Item Weight | 0.63 Ounces | | Manufacturer | Guangzhou Openfind Electronic Commerce CO., LTD | | Manufacturer Part Number | QXAD0072 | | Material | Brass | | Material Type | Brass | | Maximum Shear Strength | [EST] 275 MPa | | Metal | Brass | | Metal type | Brass | | Number Of Items | 50 | | Number of Pieces | 50 | | Size | M1.6x2.5mm(OD)x4mm(L),30 Pcs | | Thread Coverage | Fully Threaded | | Thread Size | M1.6 | | Thread Style | Metric Internal | | Thread Type | ISO Metric | | Thread size | M1.6 | ## Product Details - **Material:** Brass - **Fastener type:** Knurled - **Thread size:** M1.6 - **Exterior finish:** Brass - **Colour:** Brass Tone - **Metal type:** Brass - **Finish type:** Brass - **Brand:** Antrader - **Item dimensions L x W x H:** 4 x 2 x 4 millimetres - **Item weight:** 0.63 Ounces ## Images ![Antrader 50PCS M1.6 Female Thread Brass Knurled Insert Embedment Nut Assortment Kit - Image 1](https://m.media-amazon.com/images/I/71kpPE7naLL.jpg) ![Antrader 50PCS M1.6 Female Thread Brass Knurled Insert Embedment Nut Assortment Kit - Image 2](https://m.media-amazon.com/images/I/51wpxRFj7nL.jpg) ![Antrader 50PCS M1.6 Female Thread Brass Knurled Insert Embedment Nut Assortment Kit - Image 3](https://m.media-amazon.com/images/I/719Lskf4UgL.jpg) ![Antrader 50PCS M1.6 Female Thread Brass Knurled Insert Embedment Nut Assortment Kit - Image 4](https://m.media-amazon.com/images/I/41YlGh9ZwgL.jpg) ![Antrader 50PCS M1.6 Female Thread Brass Knurled Insert Embedment Nut Assortment Kit - Image 5](https://m.media-amazon.com/images/I/51ndZs8ryaL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Good *by S***S on 7 February 2025* Good ### ⭐⭐ They are not 5mm OD inserts.
