Abstract
This Application seeks to protect Applicant's HYTORC® Z® System which involves: tools having multi-speed/multi-torque modes with torque multiplication and vibration mechanisms without use of external reaction abutments; a force transfer means to yield in-line co-axial action and reaction for use with such tools; driving means and shifting means capable of attaching to washers under the nut for use with such tools and force transfer means; associated washers and fasteners for use with such tools, force transfer means and driving means; and related accessories for use with such tools, force transfer means, driving means, washers and fasteners. The HYTORC® Z® System includes the following: Z® Washers located under nuts or bolt heads of various types having engageable perimeters of multiple shapes, sizes, geometries and serrations, such as washer/fastener radius engagement differentials, and frictionally biased faces with relatively higher friction against the flange surface and relatively lower friction against the nut, such as friction coefficient increasing treatment means of various types, sizes and locations; HYTORC Z® Guns incorporating a powerful intermittent (impact, vibration, ultrasonic, etc.) mechanism, a precise torque multiplier in the same tool combining rapid run-down with calibrated torque; HYTORC® Z® Sockets with dual drive coaxial action and reaction having outer sleeves to react on Z® Washers and an inner sleeves to turn nuts or bolt heads; HYTORC® Z® Spline Adapters and Reaction Plates for backwards compatibility with HYTORC®'s torque/tension systems including the AVANTI® and ICE® square drive systems, the STEALTH® limited clearance system, the pneumatic jGUN® series, the FLASH® Gun and LITHIUM Series electric multipliers and more; the combination of HYTORC Z® Washer and the HYTORC® Z® Dual Friction Washer™ including a dual friction-enhanced face washer and/or the HYTORC® Z® Nut/Bolt for counter-torque under a nut or bolt head on the other side of the joint; HYTORC® Z® Dual Drive Offset Links for tight clearances while using HYTORC®'s torque/tension systems; HYTORC® Z® Vibration Mechanisms applied thereof; Z®-Squirter® Washers; Z®-DTI Washers; HYTORC® Z® Washer and Nut Assemblies; Anti-Loosening Z® Washers; and any combinations thereof. Further disclosures include: Tapered Fastener Assemblies; Tapered Torsional Couplings; Two-Part Tapered Nut Assemblies; Two-Part Tapered Thread Nut Assemblies; HYTORC® Anti-Loosening Z® Washers, Nuts and SMARTSTUDS; and any combinations thereof.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
