Pre-cut metal shims, all with a thickness of 1.00 millimeter. Many materials make suitable shim stock (also often styled shimstock), or base material, depending on the context: wood, stone, plastic, metal, or even paper (e.g., when used under a table leg to level the table surface).
Modern automatic level in use on a construction site. A level is an optical instrument used to establish or verify points in the same horizontal plane in a process known as levelling. It is used in conjunction with a levelling staff to establish the relative height or levels (the vertical separation) of objects or marks.
A machine screw is screwed into the sleeve, causing the anchor to bend, expand, spread and grip against the inside of the hole or behind it (in hollow contexts such as drywall over stud cavities, or hollow doors). [1] Mollies come in various diameters and grip lengths (shank lengths) for different drywall thicknesses and to support different ...

Franklin D. Jones, in his textbook Machine Shop Training Course (5th ed), [4] noted: "In many cases, a jig borer is a 'jig eliminator.' In other words, such a machine may be used instead of a jig either when the quantity of work is not large enough to warrant making a jig or when there is insufficient time for jig making."
A level staff, also called levelling rod, is a graduated wooden or aluminium rod, used with a levelling instrument to determine the difference in height between points or heights of points above a vertical datum. When used for stadiametric rangefinding, the level staff is called a stadia rod.
Turning is a term used when referring to moving the level to take an elevation shot from a different location. To "turn" the level, one must first take a reading and record the elevation of the point the rod is located on. While the rod is being kept in exactly the same location, the level is moved to a new location where the rod is still visible.
Bricklayer's trowel has an elongated triangular-shaped flat metal blade, used by masons for leveling, spreading, and shaping cement, plaster, and mortar.
