ABSTRACT:
An insert assembly for installation in a workpiece having a threaded hole. When the inner insert is axially received within the outer insert, the mating surfaces of these members are configured such that the inner insert applies a radial outward force to the outer insert to securely install the insert assembly in the workpiece. A stud assembly also is provided for installation in the workpiece hole. The stud assembly comprises a stud body and a stud. When the stud is axially received within the stud body, the mating surfaces of these members, like the insert assembly, are configured such that the stud applies a radial outward force to the stud body to securely install the stud assembly in the workpiece. Both the insert assembly and stud assembly are particularly adapted for use with workpieces made of relatively soft or lightweight materials.
