Abstract: A wrench connector it is used to connect a driver which has a driving lug, and a wrench with opposing ends for engaging fasteners, one of which ends is a closed end. The connector has opposing ends with an aperture extending from one end toward the other end. The aperture is adapted to receive the driving lug with the one end of the connector positioned adjacent the driver handle. The connector has a multifaceted outer peripheral wrench engaging surface adjacent the one end of the connector and adapted to be received by and drivingly engage the closed end of the wrench. The connector also has a retaining surface spaced from the one end of the connector and extends peripherally outwardly of the multifaceted wrench engaging surface to retain the closed end of the wrench between the driver handle and the retaining surface.

Abstract: A method of producing a low carbon, low alloy, martensitic, cold-worked steel is disclosed. A low alloy steel is provided having the ability to form an essentially martensitic structure upon air cooling from a temperature above its A.sub.cl. The steel is austenitized and then air cooled to form a martensitic structure. The steel is tempered and then cold-worked to reduce its cross section by about 1/32 to 1/8 inch to increase its tensile and yield strengths while at least maintaining its tempered hardness.

Abstract: The invention relates to a clevis structure having transverse pins for a universal coupling effect. The structure is an assembly of mechanically interlocking components which can be individually fabricated and releasably joined without load carrying fasteners, welding, or the like. The components are readily fabricated even in relatively large sizes.
