A strain detecting load cell which is adapted to replace or be readily interchangeable with coupling member such as a pin or bolt. The working dimensions of the cell and the part replaced are the same, except that the cell has short zones of slightly decreased diameter so that the shear strains are concentrated in these zones. An axial bore in the cell contains electrical strain gages attached to its circumferential wall within the concentrating zones and having leads for connection to exterior measuring instrumentation such as Wheatstone bridge equipment. The arrangement and orientation of the gages in the concentrating zones permit evaluation of the applied load both as to magnitude and direction.
