Earnest Quality
Poor Quality
Trim on Hex Corners: Hex head cap screws with poorly trimmed heads will have burrs extending past the bearing face.
Bearing Face: Poor quality cap screws will have undersized and poorly formed bearing faces.
Fillet Radius: Poor quality cap screws will have marginal radiuses under the head.
Thread Transition: On poor quality screws the thread runs right up to the body resulting in an area that is prone to fatigue failures.
Point: Poorly formed points make it difficult to install a nut or install the cap screws into threaded holes.
Unique To Earnest:
Large diameters, long lengths, course and fine thread
Fully threaded to the head tap bolts
