Abstract: An anchor stud includes a stud portion including a body portion having a first end that extends to a second end though an intermediate portion. A wedge member is operatively coupled to the second end of the stud portion. The wedge member includes a body having a generally frustoconical profile and is formed from a material having a Vickers hardness of between about 218 HV and about 290 HV. A sleeve element is positioned on the stud portion at the second end adjacent the wedge member. The sleeve element is formed from a material having a Vickers hardness of between about 218 HV and about 290 HV.

Abstract: Disclosed is an anchor bolt including a wedge having a surface with a plurality of protrusions and a sleeve in operable communication with the surface. Furthermore, the sleeve is expandably receptive to the surface.

Abstract: A setting tool arrangement includes a barrel of a setting tool; and a sleeve interactive with the barrel to move to a position allowing the barrel to move when pointed in a direction opposite the direction of gravity and to a position preventing the barrel from moving when pointed in a direction approximating the direction of gravity and method.

Abstract: A carrier strip system includes a plurality of discrete carrier strips respectively receptive of fasteners of substantially different dimensions the strips having internal features configured to engage the fasteners, the strips further having substantially identical external dimensions said external dimensions being substantially symmetrical with respect to a virtual surface defined by inclusion of axes of the plurality of discrete fasteners, and the external dimensions being engagable with a single setting tool magazine such that fasteners with different dimensions have consistent alignment within a single setting tool magazine and method.

Abstract: Disclosed herein is a powder actuated setting tool piston retainer arrangement which includes a housing and firing mechanism and a piston having a piston retaining ring in operable communication with the housing and firing mechanism. Further the arrangement includes a barrel within which the piston is slidably disposable. A cantilevered retainer is disposed at the barrel, the retainer being pivotally articulated with the barrel such that the retaining ring is contactable thereby to retain the piston in a selected position. Further disclosed herein is a method for retaining a piston of a powder actuated setting tool in position. The method includes urging a cantilevered retainer radially inwardly of a barrel of the setting tool for the purpose of contacting a retaining ring of the piston of the setting tool. Such contact frictionally retains the piston in a selected position.

Abstract: A drilling device for producing undercut holes. The drilling device includes a drilling tool having an axis of rotation and a cutting portion arranged such that the cutting portion drills a hole with a longitudinal axis that is radially offset with respect to said axis of rotation and a centering device operable to apply a lateral force to said drilling tool for moving said axis of rotation towards said longitudinal axis to cause said cutting portion to form an undercut in a said hole.

Abstract: Disclosed herein is a method that relates to resetting and firing a powder actuated setting tool. The method includes resetting the tool by torsionally urging a portion of a firing pin into axial alignment with a finger of a barrel of the tool and compressing the barrel of the tool toward a housing of the tool. The resetting further includes the finger urging the portion of the firing pin to a ready position in response to the compression of the barrel. The method further includes firing the tool by rotating a rotator and the firing pin to a position where the portion of the firing pin is unsupported by the finger.
