The present disclosure provides for a system to secure an anchor within a bore hole comprising a drill bit tool to be connected and secured to an improved setting tool head. The system is also comprised of an anchor removably secured to the setting tool head to optimize the setting strength of the anchor. The system is also comprised of bullets having preferred size ranges to further optimize the setting of various anchors.

A snap connector for rapid mounting of fittings in a rectangular hole in a thin wall. The snap connector includes a head part to be arranged on an outer side of the thin wall. A body part penetrates the hole when mounted. Separate retaining elements protrude from said body part, and the free end of the retaining elements is provided with a first oblique face for trap-like holding and a second oblique face for play-free supporting of the body part on or against the rim or edge of the hole in the other, inner side of the thin wall. The retaining element is a slide that is guided by walls of a channel of substantially rectangular cross-section which is formed by the body part and has opposite walls. The walls have reinforcing ribs, transverse to the channel axis, on the outer wall face facing away from the channel.

The affixing device for pieces includes an affixing element (1) that can be positioned through an opening (6) in each one of the pieces (7, 8) that are affixed to each other, that also comprises a first and second retaining elements (2, 3), which, when they are in their affixing positions, are in contact with the pieces (7, 8) that are affixed to each other, with the affixing element (1) passing through the first and second retaining elements (2, 3), and with the first retaining element (2) including an accommodation space for a tool. This configuration allows for faster and simpler assembly of the affixing device, also avoiding problems of misalignment.

A fastener system is provided that includes a spindle bolt having a threaded section and a tooling interface at a head, a bolt body at least partially mated with the spindle bolt, including an anti-rotation slot and an outer surface, a nut including an interior threaded portion and an anti-rotation extension, and an expandable ring mated with the nut and including a lower clamping surface. In a clamping configuration of the fastener system, the lower clamping surface extends beyond the outer surface of the bolt body, the interior threaded portion of the nut is threadingly engaged with the threaded section of the spindle bolt, and the anti-rotation extension mates with the anti-rotation slot. In an installation configuration of the fastener system, a diameter of the lower clamping surface is less than a diameter of the lower clamping surface in the clamping configuration.

A radial expansion system for a fastener is disclosed. The radial expansion system can include a plurality of wedge guides. Each wedge guide can have at least one guide surface. The plurality of wedge guides can be operable to be movably arranged along an axis with the guide surfaces of adjacent wedge guides opposing one another. The radial expansion system can also include a plurality of expansion wedges. Each expansion wedge can have wedge surfaces configured to slidingly interface with the at least one guide surface. Each expansion wedge can also have a clamp surface operable to interface with an interior portion of a first component. The plurality of expansion wedges can be operable to be disposed between adjacent wedge guides such that the wedge surfaces interface with the opposing guide surfaces. A second component and the plurality of wedge guides can be operable to be drawn toward one another by a fastener to cause the plurality of expansion wedges to displace radially outward from the axis such that the clamping surfaces engage and apply a clamping force to the interior portion of the first component, and thereby couple the first and second components to one another.

Mounting hardware for mounting an insulation module on a furnace wall. The hardware comprises a mounting bracket embedded within the module. The bracket has a plurality of flexible tabs, each tab having a fixed end and a free end. The free ends of the tabs are arranged about a central point and are movable (flexible) relative to the fixed ends. A mounting stud is provided having a fixed end attachable to an inner surface of a furnace wall and a free end. The stud extends from the inner surface, and the stud has an annular groove adjacent the fixed end. The stud is dimensioned to extend through the mounting bracket between the free ends of the tabs and to cause the tabs to flex as the bracket moves along the stud from the free end towards the fixed end, wherein the tabs snap and lock into the annular groove when the bracket reaches the annular groove.
