A surface mount assembly for mounting a device in a surface opening of a mounting surface includes a frame, a number of locking mechanisms, and a cam ring. Each locking mechanism includes a locking member, a locker, and a coil spring. The cam ring shifts the locker rearward to move the locking member to a deployed orientation when the cam ring is rotated in one direction. The coil spring pushes the locking member to a deployed position against a back side of the mounting surface when the locking member moves to the deployed orientation. The cam ring shifts the locker forward to secure the locking member in the deployed position when the cam is rotated in a second direction opposite the first direction.

A fastener system shifting shear stresses away from a collet body and provides clamping action to targeted structures. The fastener system includes feet in the collet body that mate with openings in a sleeve at least partially surrounding the collet body. The sleeve or the collet body includes interior threads that engage with a stud that is configured to extend through the collet body and bend the feet such that they project outward from the sleeve openings in an engaged configuration.

A coupling structure for coupling a first member and a second member includes a rod-shaped part configured to be received across a first hole formed in the first member and a second hole formed in the second member. The rod-shaped part has a first insertion portion configured to be inserted into the first hole of the first member, and a second insertion portion configured to be inserted into the second hole of the second member. The coupling structure further includes a fixing configuration, the fixing configuration being configured to fix the first insertion portion and the first member by applying an external force to the first insertion portion, and the fixing configuration being configured to fix the second insertion portion and the second member by applying an external force to the second insertion portion.

A toggle cam bolt is provided including a shank, a cam lever, a recess, and a toggle. The shank includes a first end and a second end. The cam lever is rotatably attached to the first end by a first pivot pin. The cam lever includes a lever handle and a cam lobe that is eccentric relative to the first pivot pin. The recess is located at the second end of the shank. The toggle is attached to the recess so that it is rotatable about a second pivot pin. A method of clamping two or more parts together using a toggle cam bolt is also provided.

In certain embodiments, the present disclosure provides an undercut anchor including an attachment barrel and a cylindrical plug positioned in and moveable in the attachment barrel. The attachment barrel includes a cylindrical body, an outer rim extending outwardly and away from a bottom end of the body, and a plurality of independently pivotable gripping arms extending from a top end of the body.

The affixing device for pieces includes an affixing element (1) that can be positioned through an opening (6) in each one of the pieces (7, 8) that are affixed to each other, that also comprises a first and second retaining elements (2, 3), which, when they are in their affixing positions, are in contact with the pieces (7, 8) that are affixed to each other, with the affixing element (1) passing through the first and second retaining elements (2, 3), and with the first retaining element (2) including an accommodation space for a tool. This configuration allows for faster and simpler assembly of the affixing device, also avoiding problems of misalignment.
