A method of installing and sealing a friction fastener to at least an upper substrate and a lower substrate includes providing an expandable sealant to an underhead volume of the friction fastener, installing the friction fastener through the upper substrate and into the lower substrate using a joining device, and applying heat in-situ to the expandable sealant such that the friction fastener is sealed to at least the upper substrate. The heat in-situ is applied to the expandable sealant via installing the friction fastener and/or with an external heating source disposed downstream from the joining device.

Presently disclosed is a standoff fastener for use in a compound floor structure. The threaded fastener includes a threaded standoff portion designed to accept a nut which has a diameter larger than a head portion of the standoff fastener. The head portion is located centrally within the fastener in order to reduce a tendency of the fastener to pivot within a driver during the fastening process.

A cold formed anchor for use in an insulated cavity wall includes a unitary body formed with a driver portion and having large and small diameter portions. The driver portion may be formed with structure for connecting a veneer tie to the anchor. A method of making the cold formed anchor includes cold forming a driver portion and a reduced diameter portion from a blank.

A self-drilling self-tapping fastener that provides improved performance in both drilling time and pullout force without decreasing performance in any of ductility, tapping torque, torsional strength, and tension strength.

An appliance and fastening assemblies therefore are provided. A method of mounting an object to a part of an appliance using a fastening assembly is also provided. In one aspect, a fastening assembly of an appliance includes a wall defining an engagement hole. The fastening assembly also includes a tab connected to the wall and defining a clearance hole. The tab is folded over onto the wall such that the clearance hole is in communication with the engagement hole. A fastener of the fastening assembly has a head and a shank extending from the head. The shank has threads along at least a portion of the shank. The shank of the fastener is received through the clearance hole and the engagement hole. When the fastener is torqued or driven, a portion of material of the wall is extruded into the clearance hole of the tab.

The present disclosure provides a screw and a screw assemblage. The screw includes a screw head and a screw shaft which protrudes from an underside of the screw head and has a self-forming or self-cutting thread, wherein the underside of the screw head has a bearing area and at least one annular recess extending around the shaft between the bearing area and the shaft, wherein a coating made of an elastic sealant is attached to the underside of the screw head.

A thread-forming screw which is provided in particular for thin, perforated sheet metal contains a threaded shank which below the screw head is initially configured so as to be cylindrical and then continues to a conical forming portion. The screw shank within the forming portion has a rib forming an incomplete counter thread.

A door assembly and an assembly method for a door assembly with a door skin, a support component and an interior trim component, the support component is fastened to the door skin by at least one mounting component. The at least one mounting component is also used for mounting the interior trim component since a head section of the mounting component projects from the support component and the interior trim component is mounted on the head section.

This fastening component, which is intended to assemble a first part and a second part, includes a body extending longitudinally along an axis, a head configured to allow the fastening component to be rotated about the axis, and a tip connected to the body. The body has a side wall including fastening means configured to fasten the body to the first and second parts. The tip has a side wall having a shape different from that of a surface of revolution. The tip and the body are connected by a cleavable area configured to be broken in order to detach the tip from the body.

A cold formed anchor for use in an insulated cavity wall includes a unitary body formed with a driver portion and having large and small diameter portions. The driver portion may be formed with structure for connecting a veneer tie to the anchor. A method of making the cold formed anchor includes cold forming a driver portion and a reduced diameter portion from a blank.
