A two-way nut spanner has a handle and an engaging head having a base, a first engaging portion and a second engaging portion. The base has a first abutting surface and a second abutting surface respectively located on two opposite sides of the base. The first engaging portion protrudes from the first abutting surface of the base and has multiple first engaging blocks. Each of the engaging blocks has a first inclined surface. The second engaging portion protrudes from the second abutting surface of the base and has a second engaging block having a second inclined surface. The engaging head has the first engaging portion and the second engaging portion with different engaging structures to enhance convenience for using the two-way nut spanner.

An assembly of a wrench and a socket. The wrench has a penetrating driving hole, which has a retaining ring mounted therein. The socket, having a front end and a tail end, comprises a socketing portion axially extended between the front end and the tail end thereof for driving a fastening element. The socket comprises a retaining portion formed on the periphery thereof. The retaining portion has a retaining groove arranged at retaining corners radially indented for matching the retaining ring. The retaining groove is positioned between the front end and the tail end. The retaining portion further has a buffer groove formed between the retaining groove and the front end, so as to allow the buffer groove to successively provide a buffer or damping effect with the retaining ring when the retaining groove is decoupled from the retaining ring. Accordingly, the user is allowed to control his/her force more easily and improves the operational safety for the process of pulling out of the socket.
