Loading system for loading of test pins into printed circuit board test fixtures. Test pins are loaded into a loader body, and locked thereto by a sliding locking plate through frictional engagement at an interface where in test pin hole is of a reduced surface area. Upon alignment of the loading body to the sliding lock plate, increasing surface area of each test pin hole, the test pins drop through the loading body into the test fixture. The lower surface area of the head of the test pin controls movement of the test pin between the loading body and the test fixture through gravity free fall. After circuit board testings, the test pins are reloaded back to the original location within the loader body for subsequent new circuit loading and testing.
