TAPER-LOK® is an interference fit fastening system with a self-sealing feature. The system includes a close tolerance tapered shank bolt and a companion washer-nut which is self-centering and self-locking. TAPER-LOK system derives its self-sealing ability through its tapered interference fit, which also assures accurate alignment of the structure being joined. The controlled interference provides contact and sealing between the bolt shank and total bearing area within the hole.

Style: Tension and shear, flush or protruding head, pull or stump type configurations.
