  • Fastener systems for wood with overtightening and loosening prevention
    Patent number: 11428261
    Abstract: A replacement for cylindrical dowel nuts is provided and is a hollow cylindrical nut with a threaded hole on top and an unthreaded hole at the bottom which is for the threaded shank to enter. This hollow dowel nut elastically compresses during tightening to act like a lock-washer to prevent loosening. Several solutions are provided to make the top of the nut thicker to fit more thread coils than what wall thickness would otherwise permit. To improve loosening prevention further and also provide overtightening prevention a hollow nut with flatter bottom and a narrow gap bisecting the lower hole are used which during tightening cause right and left edges of said gap to be pushed towards the bolt strongly gripping it which prevents overtightening and loosening. “C” shaped nuts also provided which cause misalignment and jamming in the thread when compressed thereby also preventing loosening and overtightening.

  • Engaging washers
    Patent number: 11396902
    Abstract: Engaging washers such as reaction washers and backup washers can include novel advantageous features. For example, an engaging washer can include an inner row of teeth and an outer row of teeth, where the teeth in the inner row can slope in a first circumferential direction to primarily engage a flange during bolt tightening, and the teeth in the outer row can slope in a second circumferential direction to primarily engage during bolt loosening. The engaging washers may also include an arched design to allow gradual increasing of contact surface areas as a clamping force in the washer gradually increases. Additionally, a reaction washer can include stepped castles for engaging a reaction socket. The castles may also include sloped or curved engaging surfaces that can provide decreased contact surface area and may also inhibit outward biasing of reaction fingers that are engaging the castles.
