Abstract: The description provides a method of forming a seal around an end of a fastener protruding from a structure. The cap includes a cap body with a cavity; a sealing material inlet comprising an opening in the cap body; three or more ridges protruding from the cap body into the cavity; and three or more channels between the ridges. The method includes: installing the cap body over the end of the fastener so that it is enclosed within the cavity and contacted by the ridges; injecting sealing material into the cavity via the sealing material inlet so that the sealing material flows along the channels, fills the cavity, contacts the end of the fastener, and contacts the structure; and curing the sealing material to form the seal.

The fastener further includes an axial annular engagement groove having a diameter larger than the shank, the annular engagement groove axially extending from the lands to a retaining collar adjacent the shank, the groove adapted to relieve material of a member on installation by receiving material as the lands in the underside of the head portion mechanically interlock with the member.

Abstract: An anchor assembly for walls comprises a toggle member and a strap member pivotally mounted together, and a locking member. In a first position, the toggle member is aligned with the strap member for insertion through a hole in the wall, whereas in a second position, the toggle member extends behind the wall angularly to the strap member which extends from the toggle member through the hole. The locking member is adapted to be displaced along the strap member until it engages the wall and to be locked on the strap member to prevent the locking member from displacing away from the toggle member. Therefore, the locking member and the toggle member are connected by the strap member and imprison the wall by abutting respectively the visible and hidden sides thereof. A fastener introduced through the locking member and wall threadably engages an opening defined in the toggle member.

Abstract: A method for inserting a component through a surface of a workpiece made of a first material uses friction-induced plasticity of the latter to attach the component to the workpiece. The component includes a head portion having a base and a working end being threaded, and an insert portion having a penetrating end and provided with a threaded bore closed at its penetrating end, to initially receive the threaded working end. The outer surface of the insert portion being made of a second material harder than the first material, a rotary tool can be used to insert the component through the workpiece surface, by rotating the rotary tool in a first direction while applying an axial force onto the head portion base to produce substantially full insertion of the insert portion, and by maintaining the axial force during a sufficient setting time without rotation to produce the attachment.

Abstract: A fastener for a vehicle lamp assembly has an adjustable stud and grommet. Positioning grooves on the stud interact with positioning fingers on the grommet in a ratcheting fashion to allow more accurate alignment of the lamp assembly prior to securing the lamp assembly to a vehicle.

Abstract: The invention relates to a locking washer which is to be inserted between a bearing element (38) and a screwable element (42) and which includes two washer crowns (12, 14), each of which has an engagement face (22, 24). Said washer crowns (12, 14) which engage with one another and are maintained compressed under axial pressure between said screwable element (42) and said bearing element (38) are capable, when said screwable element is unscrewed, of rotatably engaging with said screwable element (42), and said bearing element (38), respectively, so as to rotate said washer crowns (12, 14) relative to one another, in order to rotatably lock said screwable element (42). According to the invention, said locking washer presents a shape of a truncated cone, and said locking washer (10) is elastically deformable in order to be able to be flattened, forming a spring, such that said axial pressure is maintained substantially constant.
