TSN Wrench - Through Hole Spindle
|
|
'Blind' fasteners are increasingly being used in the Aircraft Industry. These are where the flat head of the fastener cannot be gripped in the conventional manner. Manufacturers of these fasteners include the Hi-Shear Corporation who produce the Hi-Lite range. To satisfy this requirement a range of Mountz TSN wrenches with through hole spindles has been developed.
A hexagon key is passed down the axis of the square drive shaft to hold a fastener in position while its securing nut is tightened using a torque wrench.
