DIY stud with nuts

A universal fixture for studs can actually be made from old spare parts found in the garage. Thanks to the arrangement of the tool, it is possible to work with studs of different diameters, which extend along the size of the central hole. With the help of an eccentric, the pin is clamped and it is easy to rotate using an open-end wrench or ring spanner.

Having understood the principle of this tool, you can make several of its options to cover all the required diameters.
