{"product_id":"wrench-for-m4-bolts","title":"Wrench for M4-Bolts","description":"\u003cp\u003eThis print is for a wrench that is designed to work with standard M4 Bolts with a hex head. They bolts have a 4mm screw thread, 3mm hex head, and use 7mm nuts. This print takes an insert of a 3mm allen key that is up to 60mm long, which can be replaced as needed. The bottom side has a hex driver for a 7mm nut. There are nubs next to the allen key to help make sure it does not fall out, so it might be a little tight to fit in. There is a hole above the nut driver section to allow for bolts to pass through as it is used.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eHere is the Amazon page for a pack of 20x3mm Allen Key (Hex Key) that I used.  https:\/\/www.amazon.com\/gp\/product\/B0BL277DJ1\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThese size bolts are the standard for GoBuilda robots, as used in First Tech Challenge (FTC).
