Abstract

An anchor fastener is described. The anchor fastener includes a head, a generally cylindrical shaft extending from the head, a base at a distal end of the shaft, and at least one frangible portion configured to frangibly connect the shaft to the base. The shaft includes a helical thread that extends along an outer surface of the shaft towards the distal end of the shaft. The frangible portions are separable from the base and the shaft under application of a force to the shaft. The base includes a distal surface and an engagement portion configured to engage an object to be anchored to a mounting surface and configured to hold the anchor fastener to the object before installation of the shaft through the object and into the mounting surface. The base includes a thread guide configured to support the helical thread during installation of the shaft.

Dependent claims

An anchor fastener comprising:

a head, a generally cylindrical shaft extending from the head, a base at a distal end of the shaft, and at least one frangible portion configured to frangibly connect the shaft to the base;
the shaft including a helical thread that extends along an outer surface of the shaft towards the distal end of the shaft;
wherein the at least one frangible portion is separable from at least one of the base and the shaft under application of a force to the shaft;
wherein the base includes a distal surface and an engagement portion configured to engage an object to be anchored to a mounting surface and configured to hold the anchor fastener to the object before installation of the shaft through the object and into the mounting surface;
wherein the base includes a thread guide configured to support the helical thread during installation of the shaft;
wherein the thread guide has a plurality of engagement surfaces that engage the helical thread during installation and are formed at different distances from the base according to a thread pitch of the helical thread.

An anchor fastener comprising:

a head, a threaded shaft extending from the head having a self-drilling tip, a base at a distal end of the shaft, and at least one frangible portion configured to frangibly connect the shaft to the base;
the shaft including a helical thread that extends along an outer surface of the shaft towards the distal end of the shaft;
wherein the at least one frangible portion is separable from at least one of the base and the shaft under application of a force to the shaft;
wherein the base includes a distal surface and an engagement portion configured to engage an object to be anchored to a mounting surface and configured to hold the anchor fastener to the object before installation of the shaft through the object and into the mounting surface;
wherein the head includes a flexible portion configured to flex away from the base and in a direction perpendicular to the shaft;
the base includes a protrusion that protrudes towards the flexible portion of the head;
the flexible portion is configured to engage the protrusion and flex to resist and slow rotation of the shaft during installation of the shaft.
