Examples of T-slotted profiles 1964 patent demonstrating early use of extruded T-slot members. Cross-section of 80/20 T-slotted profiles, 10 and 15 series A bicycle trailer for bike-trekking with three Euroboxes and aluminium profile framing. T-slot structural framing is a framing system consisting of lengths of square or rectangular extruded ...
The UIT rail, also known as Anschutz rail, is a standard used for mounting slings and other gun accessories in competition shooting, and is essentially a T-slot track shaped aluminium extrusion profile accepting attachments in the form of T-slot nuts, or similar. [1]
The T-slot nut slides along a T-slot track, which is set in workbench or table for a router, drill press, or bandsaw. T-slot nuts are also used with T-slot structural framing to build a variety of industrial structures and machines. A T-slot bolt is generally stronger than a T-slot nut and hex-head cap screw. [1]
Planck units is system of geometrized units in which the reduced Planck constant is included in the list of defining constants. It is based on only properties of free space rather than of any object or particle. Stoney units is a system of geometrized units in which the Coulomb constant and the elementary charge are included.
The contemporary square drive screw has all but replaced the Robertson screw proper and is commonly referred to as a Robertson because it has practically identical drive dimensions and the same colour identification system, but the contemporary square drive socket has parallel sides rather than tapered.
The workpiece is then clamped to the faceplate, typically using t-slot nuts in slots in the faceplate, or less commonly threaded holes in the faceplate itself. The faceplate may be attached to the lathe in several ways: the two most common are a thread and a precision cone arrangement, and threaded studs and a circular recess fitting a flange ...
A standard metric (concrete) block is 190 mm wide, 390 mm long, and 190 mm high, which allows for 10 mm mortar joints in between bricks, giving a standard unit size of 200 mm square by 400 mm long. [3] A standard metric brick is 90 by 57 by 190 mm; with 10 mm of mortar, that produces a standard unit of 100 mm x 200 mm. [3]
Cross section diagram of standard strut channel. Basic strut channel comes in the open box section 1 + 5 ⁄ 8 in (41 mm) square. A half height 1 + 5 ⁄ 8 in × 13 ⁄ 16 in (41 mm × 21 mm) version is also available, used mostly where mounted directly to a wall as it has significantly less stiffness and ability to carry loads across an open space or brace.
