Accurate reaction socket access within an outer washer diameter is provided via a number of tool access castles extending from a stepped bushing and serration top, which in turn provides low friction during initial tightening and securing after final loading of a nut/bolt. Bottom serration slipping during initial tightening and thread locking during initial loosening are eliminated by the reaction washer stacked on top and in contact with a support washer via helical ramps and ramp mates. During initial tightening or loosening, the ramp mates slide up or down the helical ramps whereby an axial load on the nut/bolt is ramped up or down prior to screwing it on the main thread. A clamp ring or ramp indenters may secure the two washers. An interposition washer may extend the axial reaction range of the washer stack. Direct tension indicators may be combined with the ramp indenters.

A dual positionable adaptor for a fastener driver assembly employs a tandem guide assembly mounted to a guide head which has an entry reference surface defining an opening for a fastener to provide a proper location and entry angle for the fastener. A pair of wings each defines a pair of reference engagement edges which engage either an upper horizontal member or a lower horizontal member. The wings, together with the entry reference surface, define a proper entry location and angle for connecting a vertical stud to either an upper plate or a lower plate. The selected adaptor position is achieved by securing the adaptor in one of two angular positions relative to the tube axis of the fastener driver assembly. The wings are also affixed with squirrel claws to lock the adaptor in place for installing the fastener. The adaptor also includes flush indicators to indicate that the proper flush position of the reference surface against the vertical member is achieved. The wings are independently pivotal to accommodate situations wherein the tandem wing configuration cannot be employed. The fastener is retained within the adaptor fastener channel via a magnet assembly.

The present invention 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 for use with such tools, force transfer means and driving means; and related accessories for use with such tools, force transfer means, driving means and washers. HYTORC 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 impact mechanism and 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 square drive system, the STEALTH limited clearance system, the pneumatic jGUN series, the FLASH Gun electric multiplier and more. HYTORC Z Washer and HYTORC Friction Washer combination including a dual friction-enhanced face washer for counter-torque under a nut or bolt head on the other side of the joint; and HYTORC Z Dual Drive Offset Links for tight clearances while using HYTORC's torque/tension systems. Z-Squirter Washers, HYTORC Z Washer and Nut Assemblies, Tapered Fastener Assemblies, Tapered Torsional Couplings, Two-Part Tapered Nut Assemblies and any combinations thereof are further disclosed.

A drive system for an industrial tool (e.g., a hydraulic torque wrench) includes a cylinder, a first piston, a first rod, a second piston, and a second rod. The cylinder includes a first end, a second end, and a longitudinal axis extending therebetween. The first piston is disposed within the cylinder and movable along the longitudinal axis. The first rod is coupled to the first piston and extends toward the first end of the cylinder. The second piston is disposed within the cylinder and movable along the longitudinal axis. The second rod is coupled to the second piston and extends toward the first end of the cylinder.

A reaction arm for use with a torque generating device, the reaction arm including a reaction bar, and a body portion having a first internal diameter, and having formed on an internal surface thereof a female spline having a second internal diameter and a guide bushing having a third internal diameter, the first, second, and third internal diameter being distinctly sized.

A torque wrench assembly includes a torque wrench head being adapted to both tighten and loosen a fastener, wherein the torque wrench head includes fastener engaging means and drive means for driving the fastener engaging means. The torque wrench assembly also includes means for mounting the torque wrench assembly on a support means, wherein the torque wrench head and the mounting means are adapted so that the torque wrench head is capable of both tightening a fastener and loosening a fastener.

The invention relates to a two-part tapered thread nut assembly (3402) including: a rigid inner member (3410) having an inner surface (3411, 3421) threadedly engagable with the fastener and an outer surface (3412, 3422) defined by a thread formation that forms a taper; an outer member (3420) having an inner surface (3411, 3421) defined by an inversely tapered thread formation (3425) that is threadedly engagable with the tapered thread formation (3416) of the outer surface (3412, 3422) of the inner member (3410); and wherein the two-part nut assembly (3402), when rotated by an action portion of the torque device, applies a load to the threaded fastener.

The invention is related to a threaded fastener for fastening objects including: a stud rotatably coupled to a stud-head having a bottom surface; and the bottom surface having friction coefficient increasing treatments biased in areas outward from the stud.

A fastener installation assembly has a head with a fastener opening and a connector for connecting the head to a driving tool so that a fastener can be driven through the hole. A guide assembly with a locator is pivotally mounted to the head. The locator may be removable from the guide assembly and movable so that its locator surface is movable relative to a guide surface of the guide assembly. The locator may include a locator guide that is movable relative to the locator so that a position of an end of the locator guide relative to the locator surface is adjustable. The locator guide may be removable from the locator. The guide assembly is pivotable between multiple angular positions to vary the angle at which a fastener is driven into building materials which the guide assembly and locator engage.
