Abstract Adaptors for use with conventional socket wrenches to convert U.S. inch dimensions to metric dimensions are identified to readily establish the specific metric sized nut or bolt which a specific U.S. inch sized wrench is designed to apply torque to with the accommodation of the adaptor. The adaptor comprises a band of material conforming to the socket nut wrench or bolt torquing surfaces on its outside surfaces and conforming to a smaller metric bolt or nut wrenching surface on its inside surfaces. The adaptor material is of sufficient compressive strength to transmit normal wrenching torque forces between the inside surfaces of the socket wrench and the nut or bolt wrenching surfaces without permanent deformation of the adaptor. The adaptor thickness is designed to adapt one particular socket wrench size to accommodate one particular smaller size metric nut or bolt.
A wrench size-reducing adaptor for reducing the torquing surface of a wrench to make the wrench effective to apply torque to a member to be turned which has a wrenching surface that is normally too small to be turned by the wrench comprising: a resilient, single-piece, split-ring formed with a thickness defining outer and inner periphery patterns to fit a specific size wrench and a specific size member to be turned respectively, said split ring being formed so as to tend to expand outwardly with force against the inner periphery of an oversized wrench when the adaptor is forced into said wrench to hold it securely therein, and means affixed to said ring identifying the specific sizes of said outer and inner periphery patterns of said ring.

Claim 3
Dependent Claim

Apparatus as set out in claim 2 wherein the outer periphery of said ring corresponds to a specific wrench size in inches and the inner periphery of said ring corresponds to a specific metric size of a member to be turned.
Claim 5
Dependent Claim
