GT Cap Bolt (GT-SA Model)

Loosening countermeasure for class 12.9 (tensile strength of 1200 N/m ㎡ or more) parts

[Features]
· Excellent vibration resistance is highly effective at preventing looseness.
· An optimal washer is selected to eliminate sinking of the bearing surface, and also achieve a suitable bolt tightening torque, so dimensional variation is limited even when high axial torque is applied.
· The washer need not be assembled with the bolt, which improves workability and lowers the fastening cost.
