  • Patent number: 10531905
    Abstract: A compression screw for applying compression at a bone joint. The compression screw includes an axial screw body extending from a distal end to a proximal end with the distal end including a series of bone engaging threads configured to be self-drilling and self-tapping and the proximal end including a head which defines a radially extending shoulder. At least one proximal rotary cutting structure is defined proximally of the bone engaging threads. The at least one proximal rotary cutting structure is configured to be self-drilling such that a proximal portion of the axial screw body cuts into and advances within a bone of the bone joint as the axial screw body is advanced. A method of inserting the compression screw is also provided.

  • Patent number: 10406590
    Abstract: A hollow screw and related process of making is provided, wherein the hollow screw is formed from a generally circular corrosion resistant stainless steel disk cut from flat roll stock. The hollow screw includes a head and an elongated and hollow shaft having a wall thickness between about 0.2 to about 0.7 millimeters extending therefrom and defining a shank portion and a threaded portion having a plurality of threads thereon with a rotational drive mechanism configured to facilitate tightening via the threads. The process involves annealing to soften the stamped hollow screw, followed by thread rolling, and then age hardening the hollow screw. As such, the resultant hollow screw is relatively lightweight, about 50% the mass of a solid core screw made from the same material, with a sufficient thread strength to meet most aerospace applications and contributes to important aircraft fuel economy.

  • Patent number: 8545152
    Abstract: The invention relates to a screw which can be screwed into a component and which will resist further screwing into an internal thread within said component once a maximum torque has been reached. For this purpose, a screw body having an external thread is combined with a screw drive element which projects into a bore within said screw body and, within said bore, is connected to the screw body via static friction. At least part of this combination is made of a plastic material, with the static friction having the effect of a slipping clutch when a maximum torque acts on the screw drive element. The screw drive element is connected to the screw body via a ratchet in such a way that when the screw body is unscrewed from the internal thread within said component, turning said screw drive element will cause the ratchet to engage, thereby entraining the screw body.

  • Publication number: 20110081219
    Abstract: A fastening mechanism which is easy to handle and operate. The fastening mechanism includes a bolster, a bolt, at least two elbows, and a support bracket. The bolster is provided with several retainer walls externally disposed, one side thereof being formed into an opening and the inside thereof being formed into a hollow space with a passage through which the bolt can pass. At least two elbows extend from the bottom end of the retainer walls. When the bolt mates with the inner thread formed in the retainer wall, a friction plate formed with the support bracket lodges into a tapered slot between two retainer walls so that the support bracket cannot move against the retainer walls. The at least two elbows angle outwards to retain the support bracket when the bolt is traveling along the inner thread.

  • Patent number: 7341414
    Abstract: A fastener and a method for reducing stress failure in a fastening joint of an internal combustion engine component are provided. The threaded fastener may be a bolt or a stud secured to an engine block. The fastener has a threaded tip portion with a radius and a distal end. The threaded tip portion is inserted into a threaded hole to define a threaded interface. In one embodiment, the load carrying capability is increased by progressively reducing the radius of at least a part of the threaded tip portion. In another embodiment, the load carrying capability is increased by an axially extending hole at the distal end of the threaded tip portion, the hole having a progressively reduced diameter.
