Accu-Lok® blind bolt
The Accu-Lok® blind bolt is designed specifically for use in composite structures. It combines high joint preload with a large diameter footprint on the blind side, which provides a wider distribution of the joint preload. The large blind side upset enables the fastener to exert a very high clamping force to the structure without delaminating the composite material. The Accu-Lok® II blind bolt and Accu-Lok® IIa blind bolt are available with a non-threaded Dryv-Cap™ installation mechanism. The Dryv-Cap™ mechanism is a disposable driver that positively engages the driving recess in the fastener and eliminates the wear associated with conventional drivers.
