PURPOSE: An apparatus for measuring a metal nut insert of a synthetic resin product is provided to accurately measure whether or not a metal nut is embedded in a precise depth according to the design. CONSTITUTION: An apparatus for measuring a metal nut insert of a synthetic resin product comprises an upper body(3), an intermediate body(4), a lower body(5), a product supporting part(6), a lower spring, a nut supporting part(7), and an upper spring. The upper body is fixed and installed on the top of an upper plate of a table. The intermediate body is elastically supported by the bottom of the upper body to be separated. The product supporting part is slidingly inserted in a hollow part of the upper body. The upper end of the product supporting part is protruded higher than the upper end of the upper body, and the lower end thereof is fixed on the intermediate body by a key bolt. The upper end of the lower spring elastically supports the product supporting part in a state where the lower end of the lower spring is elastically supported on the top of the intermediate body. The nut supporting part comprises a slide support part and a lot.
