Abstract: A low-profile rivet-like fastener (10) is adapted to be mounted in a hole (19) provided through a wall (15). The improved fastener broadly includes: an elongated tubular body (11), a nut (12), a ring (13), and a retainer (14). The body has a front end and a rear end. A flange (22) extends outwardly from the body adjacent the front end. The body has an inwardly-extending lug (27) adjacent the body rear end. The nut (12) has a head portion (30) and a collar portion (31) extending forwardly from the head portion. The collar portion (31) has an intermediate portion passing through the lug and terminates in a marginal end portioned forwardly of the lug. The ring (13) loosely surrounds the collar marginal end portion. The retainer (14) prevents the ring from separating from the collar marginal end portion.

Abstract: A low-profile rivet-like fastener (10) is adapted to be mounted in a hole (19) provided through a wall (15). The wall has a forwardly-facing surface (16) and an opposite rearwardly-facing surface (18). The improved fastener broadly includes: an elongated tubular body (11), a nut (12), a ring (13), and a retainer (14). The body has a front end and a rear end. A flange (22) extends outwardly from the body adjacent the front end. This flange has a rearwardly-facing surface (23) adapted to abut a marginal portion of the wall forwardly-facing surface (16) about the hole. The body rear end having a rearwardly-facing surface (24). The body also has an inwardly-extending lug (27) adjacent the body rear end. The axial extent of the lug being defined between the body rearwardly-facing surface (24) and a forwardly-facing annular surface (29) on the body. The nut (12) has a head portion (30) and a collar portion (31) extending forwardly from the head portion.

Abstract: This invention provides a fastener (20) that is adapted to be mounted in a hole provided in a wall (not shown). The improved fastener comprises: an elongated tubular body (21) having a first end (23) and a second end (24), having an outwardly-extending flange (25) adjacent the first end, having an intermediate portion (27), and having a distal marginal end portion (37) adjacent the second end, the body also having an abutment surface (32) facing toward the second end; and a member (22) adapted to be inserted into the body through the second end, the member having an abutment surface (40) adapted to bear against the body abutment surface, and having an outer polygonal surface (41); and wherein the body marginal end portion (37) is adapted to be plastically deformed about the member to hold the member within the body.
