The locking portion comprises, for example, three locking teeth. | 06-07-2012 |
20120148369 | SEALING WASHER ASSEMBLY FOR LARGE DIAMETER HOLES ON FLAT SURFACES - A sealing washer assembly includes a main washer with a bottom annular groove for a removable O-ring and a top recess for a sealing washer. A fastener such as a screw or bolt passes through the sealing washer and the main washer, into a hole in a mounting surface. When the fastener is tightened, the main washer is clamped to the mounting surface to create a metal-to-metal seal, the O-ring is deformed to create a seal between the main washer and the mounting surface, and the sealing washer is deformed to create a seal between the fastener and the main washer. | 06-14-2012 |
20130034403 | SCREW COMPONENT WITH A WATERPROOF STRUCTURE - A screw component with waterproof structure includes a screw body and a resilient waterproof member. The screw body has a screw head and a thread portion. The thread portion is connected to a side of the screw head for being screwed into a screwing structure. The resilient waterproof member includes a resilient body and at least one waterproof structure. The resilient body surrounds the screw head, and the at least one waterproof structure is disposed around a periphery of the resilient body. A width of the at least one waterproof structure is increasing from a side close to the thread portion to a side far from the thread portion. The at least one waterproof structure seals a hole on a housing cooperatively with the resilient body when the screw body screws the housing onto the screwing structure. | 02-07-2013 |
20130280010 | WATERPROOF SCREW, SEALING MATERIAL, METHOD FOR STRUCTURE INSTALLATION, AND STRUCTURE FOR STRUCTURE INSTALLATION - A waterproof screw includes a screw member including a head portion and a shank portion and a sealing material covering the circumference of the shank portion. The sealing material has a shear storage elastic modulus G′ at 25° C. and a frequency of 1 Hz of 50000 Pa or less. | 10-24-2013 |
20130336742 | IMPACT-DRIVABLE SCREW WITH ELASTOMER SEAL AND TIP HIGHLIGHT - 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. | 12-19-2013 |
20140017032 | WASHER ASSEMBLY - A washer assembly is configured to isolate a work-piece from a fastener and/or another structure. The washer assembly includes a rubber isolator having at least one protuberance configured to directly contact a surface of the work-piece, and a metal strengthening member permanently secured to the rubber isolator. The protuberance(s) is configured to be compressed during a normal operating condition. The metal strengthening member is configured to be compressed during a peak operating condition in which greater force is exerted into the washer assembly than during the normal operating condition. | 01-16-2014 |
20140072387 | Bonding Fastener with Environmental Seals - A bonding fastener having two components which electrically bonds metallic surfaces through serrated metal teeth on the underside of the head of the first component and on the inside surface of the second component which embed into each metal surface as a fastener is tightened. In one embodiment, the fastener is a nut and bolt combination, and in another embodiment the fastener is a two-part rivet. A sealing material circumferentially outward from the teeth on both the first component and second component creates an air-tight and water-tight seal around the teeth, protecting the bonding location from air and water infiltration from the outside. The second component also has an internal seal, sealing around the shank of the first component to prevent axial infiltration of air or water along the shank and protecting the bonding locations from corrosion from contaminants entering along that route. | 03-13-2014 |
