Adds a groove on both sides in order to facilitate insulation. X Express services not available
● When using a urethane washer on the stopper bolt, be careful of the forming dimension of the counterbore depth (W) for securing the stroke (S). ● The dimension of the stopper bolt is set so that the head is recessed 2mm below the mounting plate. (See "Stopper Bolt STBG" on P.915 .) When using a urethane washer, the relationship between the counterbore depth (W) and the stroke (S) is [W = S + Urethane Washer Thickness T + stopper bolt head thickness K + 2].
