These are hooks (10 of the same size) used for screwing into wooden substrates of walls, boards, and furniture, and for hanging and fixing hardware. This is a description and price for the item with the number at the beginning of the product name. This is the first hook. To help you visualize the installation, I've attached them to a white-painted board and a brown-painted board. (A different item from the image will be shipped) I've taken pictures from various angles, including in sunlight, shade, and close-ups, so please take a look. Made of aluminum alloy, so it is resistant to rust. Size (See image 2) A. 22mm B. 10mm C. 10mm How about for DIY projects? If you want multiple, please comment. No price reduction, no smokers, ships on weekdays, simple packaging, also listed on other sites. Thank you. Total 24g
