An elastic fastener 1 comprises a hollow tubular portion 7, an internally threaded portion 2 provided at one of the ends of the tubular portion 7, and a flange 9 formed at the other end of the tubular portion 7. The tubular portion 7 and the flange 9 are integrally formed of an elastomeric material, such as a styrene-based elastomer, a polyamide-based elastomer and a polyester-based elastomer. The internally threaded portion 2 is formed of a rigid resin material such as a polycarbonate resin. The internally threaded portion 2 is integrally fixed to the tubular portion 7 in a hole of the tubular portion.

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.

A device for securing a panel or the like to a mounting stud having external teeth includes an annular first body having an inner periphery and at least one lock finger extending from such inner periphery. An annular second body has a center opening, at least one lock opening spaced from the center opening for receiving the lock finger to lock the first and second bodies together, and at least one leg extending inwardly overlying the center opening for engaging the external teeth on the mounting stud. The second body is adapted for assembly to the first body with a panel or the like between the bodies such that the center opening can be mounted over the mounting stud with the at least one finger engaging the teeth on the mounting stud to prevent removal.

An asymmetric thread impact drivable screw and clip for use with a power impact device for penetrating wood fibers while minimizing cut fibers. The screw includes an impact head and a conical shaped tip having a ballistic insertion angle at the ends of a shank. The shank defines asymmetrical threads with an insertion flank having a long side at a slide angle peaking at a crest supported by a catch flank positioned at a grip angle. Varying tool accepting recess are taught for the head along with multiple thread sections. A mushroom compaction thread section is also taught.

A snap lock separatory panel and retainer system includes either a screen wire panel with laterally spaced, longitudinally extending locking bars defining a locking profile, or a urethane panel with laterally spaced, longitudinally extending lips or flanges which also define a locking profile. A retainer system is provided for use in securing these panels. The retainer system utilized center retainers that are engagable with industry standard holes in screen stringer rails of a vibrating separating machine. Each center retainer is provided with an array of retainer pins which are spaced to interdigitate with either screen wire tie rod ends or with urethane panel wall recesses to support the screen panel locking bars or the urethane panel flanges adjacent the retainer pins. Locking strips are provided with undercurrent bores that terminate in undercut receptacles. These bores and receptacles are sized to receive center retainer pin shanks and heads. The locking strips and center retainers cooperate to positively secure the snap lock screen wire panels and/or urethane panels in place on a vibrating separatory machine.

The installation tool for a mushrooming expandable anchor has a hollow cylindrical sleeve with an inside diameter, the top having slots for engaging the base of the mushrooming component and a means for engaging and turning a threaded component, which compresses the mushrooming component. The means for turning the threaded component can be a socket, which rotates inside of the sleeve and engages a hex head at the base of the threaded component or alternatively the means for turning the threaded component can be a threaded rod for threading into the base of the threaded component until it reaches the end of the threads in the base. Another means of turning the threaded component is a screwdriver engaging a slot in the treaded component. All of the means for turning the treaded component may be by a powered drill with a connective adapter.

The invention provides a single-edge fastening bolt. The singe-edge fastening bolt comprises a screw and a bolt head at one end of the screw. A gasket, a sleeve and a conical head are sequentially arranged on the screw from the end of the bolt head in a sleeved mode. The conical head is provided with a screwed hole which is in threaded connection with the screw, the gasket is in clearance fit with the screw, the sleeve is also in clearance fit with the screw, the outer diameter of the sleeve is larger than the inner diameter of the gasket, a plurality of axial cracks are formed in the end, close to the conical head, of the sleeve, the smaller end of the conical head is clamped into the sleeve, and the outer diameter of the larger end of the conical head is larger than or equal to the inner diameter of the sleeve. According to the single-edge fastening bolt, on the premise that the installation speed and the node strength are not lowered, the problem that when sealed section part bolt connection is completed through a traditional method, an opening of a connected section is weakened, and the single-edge fastening bolt has the advantages that installation is convenient and quick, the requirements for sealed section part connection are met, and the integrity of the connected section is guaranteed.

A vibration resistant fastening system including a high fatigue strength bolt made from a first material and a nut made from a second material that is softer than the first material of the bolt. The bolt includes bolt threads and the nut includes pre-tapped nut threads that match with the bolt threads. The fastening system utilizes a combination of unique geometry of the nut and bolt threads and a hardness differential between the nut and bolt to provide vibration resistance. When tightened, crests of the bolt threads embed into the soft bearing flanks of the nut threads. Simultaneously with the bolt crest embedment, the softer nut thread crests flow radially inward into the root radius of the bolt threads. This complete contact between the nut and the bolt restricts the nut from moving in a transverse direction relative to a longitudinal axis of the bolt.

A self-anchoring fastening device for laminating sheets of material such as sheets of metal used in constructing metal buildings. The anchor comprises a collapsible anchoring portion having radially expanding anchoring strips, which will not pull out of a hole drilled in the sheets. Threads internal to the expandable anchor cooperate with threads on a bolt inserted therein to collapse the expandable anchor, providing anchoring strips over one sheet such that the expandable anchor cannot be pulled out of the hole. A washer between the base of the collapsible anchoring portion and one sheet provides for a waterproof fastener such that the building will be watertight. The anchor is easy to install by placing the anchoring device though aligned apertures in two sheets and then turning the bolt relative to the collapsible anchoring portion to extend the radially expanding strips thus securing one sheet to the other.
