TECHNICAL FIELD
[001] The embodiments herein generally relate to fastener tools, more particularly but not exclusively to a tool specifically for holding a nut and turning or tightening a pin or bolt relative to the nut.
BACKGROUND
[002] Conventionally a spanner and a screw driver are used for tightening a pin on a nut of a fastener assembly, for example, a XM CV. The spanner holds a 10 hexagonal nylock nut and with the help of the screw driver the pin is tightened. Yet, occasionally the spanner can slip from the fastener assembly which thereby leads to an injury to an operator. Further the slippage of the spanner can incur a loss of time at the work station.
[003] Further when using a socket wrench to install or remove a nut or 15 bolt, there is a tendency for the nut or the bolt to fall out of the socket when it is not engaged. When the nut or bolt is engaged, the retaining force on the nut or bolt is much greater than the holding force on the socket. Therefore, the wrenching tool, including the socket, can be retracted off of the nut or bolt.
[004] Therefore, there is a need for a tool specifically for holding a nut and 20 turning or tightening a pin or bolt relative to the nut that eliminates the aforementioned drawbacks.

The tool (100) includes a frame (102), wherein the frame (102) has opposing first and second ends (102a and 102b). A tightening member receiving portion (not shown) and a tightening member (104) are present at the first end (102a). A socket 30 portion (not shown) at the second end (102b), and a socket (106) are present in the
5/10
second end (102b). The socket (106) defines an internal cavity (106a). The socket (106) defines a central opening (106b).
[0016] The tool (100) includes the frame (102). The frame (102) includes the first end (102a) and the second end (102b).Further, the frame (102) includes a through hole which extends from the first end (102a) to the second end 5 (102b).The frame (102) is a cylindrical member. The cylindrical member is adapted to receive a portion of the tightening member (not shown) and the socket (106). The frame (102) includes the tightening member receiving portion (not shown) at the first end (102a) and the socket portion (not shown) at the second end (102b). The frame (102) includes a knurled outer surface to facilitate gripping 10 of the tool by an operator. However, it is also within the scope of the embodiments hereinto implement/practice any type of surface which can be held by the operator without otherwise deterring the intended function of holding and tightening a fastener assembly as can be deduced from the description and corresponding drawings. 15
[0017] The tool (100) includes the tightening member (104).The tightening member (104) includes a first shank portion (104a) which is received in the tightening member receiving portion (not shown) at the first end (102a) of the frame (102).The first shank portion (104a) of the tightening member (104) has a predefined diameter d1. Further, the tightening member (104) includes an 20 enlarged diameter shank portion (104b) extending from the first shank portion (104a).The enlarged diameter shank portion (104b) has a predefined diameter d2.Further, the tightening member (104) includes a head (104c) extending from the enlarged diameter shank portion (104b) at one end. The head (104c) includes at least two arms which are defined perpendicular to an axis of the shank 25 (104a).Furthermore, the tightening member (104) includes an engaging portion (104d) which is defined at on the other end i.e. the engaging portion is formed at end of the first shank portion (104a).The engaging portion (104d) is adapted to engage with a fastening member of the fastener assembly.
