Abstract
Repeated inserting, tightening, loosening, and removing of external threads to internal threads can increase the likelihood of cross threading and thread damage. A spring loaded gear bolt assembly, which promotes alignment of mating threads before applying torque, is described. A spring is disposed on the back end of a bolt shaft to promote alignment of lead mating threads before twisting to engage external to internal threads. A gear chain translates a single hand rotation to thread two bolts into respective affixed internal threaded holes, simultaneously. A spring loaded gear bolt assembly and method described herein promote increased thread life and ease of use ease for test plate securing. Efficient single handed manipulation of multiple bolts simultaneously can be achieved using a test plate assembly, which included spring loaded gear bolt assemblies, as described herein. Applications of a spring loaded gear bolt include infrared adapter test plate assemblies.
