The present invention provides a stud and tool to remove the same.

A fastener for connecting a first housing part of a steam or gas turbine to a second housing part of the turbine which is made of a parent metal with a high degree of stress relaxation.

A torque tool to remove a sensor body includes a substantially circular base, the base having a substantially hexagonal interior extending away from the circular base, the circular base having an exterior that extends into an outer hexagonal body; and an elongated opening extending from a rim of the base to the hexagonal interior, wherein each tip of the hexagon interior has a corner relief.

The present invention relates to an apparatus for grading sensitive products. The apparatus treat the objects to be graded gently and is accurate and may be constructed so as to handle extremely large quantities. The grading device of the present invention has grading channels that are wider at the outlet than at the intake. The belt machine draws the objects forward between two inclined belts which form the channel. An adjusting device is implemented perpendicular underneath the belts of the apparatus comprising alternatively arranged support members and adjusting members arranged on an adjusting screwing shaft. Both components comprise screwing sections which regulates an increase or a decrease in the gap between the support members when the adjusting screwing shaft is rotated.

A threaded plug includes a structure which extends along an axis and includes a head, a body provided with an outer thread, and a clamping flange inserted between the head and the body; wherein the head includes, along the axis, at least one first portion having an outer lateral surface which features a first profile and at least one second portion having an outer lateral surface which features a second profile which is not coincident with the first profile.

In a fastening device for fastening a bolt, a male thread is formed on a side surface of a bolt head part, and a part to be engaged is formed on a top surface of the bolt head part. The fastening device includes a bit having a tension rod having a rod female thread part, and an engaging part installed inside the tension rod and engaging the engaged part, the bit causing the bolt to rotate where the engaged part and engaging part are engaged; a supporter surrounding the tension rod in the circumferential direction such that the lower end part thereof protrudes below the lower end part; a sensor for sensing vertical compression force acting on the supporter; a first motor for causing the bit to rotate about the axis; and a second motor for causing the tension rod to rotate about the vertically extending axis.

Fasteners, drivers, punches, fastener systems, and methods of making fasteners, drivers, punches, and fastener systems are disclosed herein. The fasteners, drivers, punches, and fastener systems include, in one example, stabilizing ribs and corresponding recesses.

A screw element is disclosed having a shaft with an outside screw thread and a longitudinal axis extending along the shaft and thereby defining a distal direction and a proximal direction, and an insertion direction and an opposite removal direction, and has a tool attachment point starting radially inwards and the tool attachment point has a central opening and in the wall of this opening at least five tooth profiles directed radially outwards and mainly parallel to the screw axis directed radially outwards and mainly parallel to the screw axis are formed in the wall of this opening, and for each tooth profile an insertion wall in insertion direction and a removal wall in removal direction can be separated, characterized in that the surface of the insertion wall is greater than the surface of the removal wall.

Methods and apparatus for a fastener head having a dual zone socket area and a mating driver bit according to aspects of the present technology include a fastener configured with driving surfaces adapted to provide enhanced engagement between each other during use. The fastener includes a recessed socket area with a sidewall that has an upper inwardly tapering section and a lower vertical section that extends to the bottom of the recessed socket area. The upper inwardly tapering section of the sidewall may also include an offset relative to the lower vertical section to create asymmetrical driving and removal surfaces. The technology also includes a corresponding mating driver bit configured with mating surfaces to the fastener to provide enhanced engagement between the fastener and mating driver bit. The technology also allows either the fastener or the driving bit to be used with preexisting fasteners and driver bits.

An aircraft monument floor attachment stud may include a body configured to pass through an opening of an aircraft monument, and a head. The body may include a body diameter. The body may be configured to couple to a fitting inserted into a mount point installed within an aircraft cabin floor. The head may include a tool section with a tool section diameter less than the body diameter. The tool section may be configured to receive a predetermined amount of torque from a tool to secure the aircraft monument to the fitting. The head may include a shaped section with an intermediate diameter greater than the tool section diameter and less than the body diameter. The shaped section may include at least one shaped portion with at least one sloped wall, and may be configured to provide a transition between the tool section diameter and the body diameter.
