Review: I was tired of so many things requiring 3M screws and the HW store not having the length I needed. To my surprise the plastic box is small and compact and looks like it will hold up. Quality of the screws is consistent (excellent) so I trust them to hold and not break. Review: Purchased these for my multirotor hobby. High quality hardware in a sturdy box. Good selection to get familiar with lengths your going to need. Screws seems to be consistent in length. Will definitely buy again ## Features - 12.9 Grade High Tensile Alloy Steel, Hardness: HRC 39-44; Black Oxide Finish - Screw Head Style: Button ; Screw Drive Style: Hex Socket, Hex Size 2mm - Head Diameter: 5.5mm, Head Height: 1.7mm; Thread Size: 3mm, Thread Pitch: 0.5mm - 5 Sizes: M3 x 6,M3 x 8, M3 x 10, M3 x 12, M3 x 16, Thread Length: 6mm, 8mm, 10mm, 12mm, 16mm - Package: 250 Pcs M3 Hex Socket Button Head Cap Screws, 50 of Each Size, Come in an Easy-use Storage Case ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Q45TMDG | | ASIN | B07Q45TMDG | | Brand | iexcell | | Customer Reviews | 4.9 4.9 out of 5 stars (58) | | Customer reviews | 4.9 4.9 out of 5 stars (58) | | Date First Available | 12 May 2019 | | Drive System | Internal Hex | | Exterior Finish | Black Oxide | | Fastener Type | Socket Screws | | Head Type | Button | | Item Hardness | Grade 12.9 | | Item model number | BM306165531-12.9 | | Manufacturer | iExcell | | Manufacturer | iExcell | | Material Type | Steel | | Metal Type | Alloy Steel | | Model | BM306165531-12.9 | | Number of Pieces | 50 | | Package Dimensions | 14.2 x 9.5 x 1.9 cm; 200 g | | Part Number | M3-0616B-12.9 | | Screw Head Style | Button | | Screw Point Style | Flat Point | | Set Name | M3 x 6 (50pcs), M3 x 8 (50pcs), M3 x 10 (50pcs), M3 x 12 (50pcs), M3 x 16 (50pcs) | | Thread Coverage | Fully Threaded | | Thread Size | M3 | | UPC | 601629960630 | ## Product Details - **Exterior finish:** Black Oxide - **Fastener type:** Socket Screws - **Head style:** Button - **Material:** Steel - **Thread size:** M3 ## Images ![iExcell 250 Pcs M3 x 6mm/8mm/10mm/12mm/16mm 12.9 Grade High Tensile Alloy Steel Hex Socket Button Head Cap Screws Kit, Black Oxide Finish - Image 1](https://m.media-amazon.com/images/I/71ARqPcsq4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by W***Z on 26 July 2019* I was tired of so many things requiring 3M screws and the HW store not having the length I needed.
