T-SHAPED THUMBSCREWS KNOBS for Imperial socket cap screws

This is a set of T-shaped knobs for use with imperial sized socket cap screws.These are quick to print and simple to use. Simple tap the screw it - no need for glue or epoxy.The perimeter of the opening where the screw is inserted has a number of ridges that lock in the screw. You will need a mallet or other tool to tap in the screw.The knobs are for imperial sized screws no. 8, no. 10, 1/4 , 5/16 and 3/8. The knobs were sized for standard screws. There is a an allowable range of tolerances for screws so you may need to shrink or expand the knob in the slicer. I suggest you print a sample to test fit.3D PrintingA print setting is provided
