A heavy duty office staple might be designated as F1667 STFCC-04: ST indicates staple, FC indicates flat top crown, C indicates cohered (joined into a strip), and 04 is the dash number for a staple with a length of 0.250 inch (6 mm), a leg thickness of 0.020 inch (500 μm), a leg width of 0.030 inch (800 μm), and a crown width of 0.500 inch ...
Stud-welded anchors on a bridge girder. Drawn arc stud welding joins a stud and another piece of metal together by heating both parts with an arc. The stud is usually joined to a flat plate by using the stud as one of the electrodes. The polarity used in stud welding depends on the type of metal being used. Welding aluminium, for example, would ...
With respect to shape, stud bolts a.k.a. studs are categorized into three basic types: "fully threaded stud bolts", "tap-end stud bolts", and "double-end stud bolts". Each of these studs have different application. As name suggests, fully threaded studs have full body coverage with threads for full engagement of the matings nuts or similar ...
A split pin, also known as a cotter pin, or cotter key in the US, [1] is a metal fastener with two tines that are bent during installation, similar to a staple or rivet. Typically made of thick wire with a half-circular cross section, split pins come in multiple sizes and types.
The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...
This generally makes forge welding more versatile than cold-diffusion techniques, which are usually performed on soft metals like copper or aluminum. [7] In forge welding, the entire welding areas are heated evenly. Forge welding can be used for a much wider range of harder metals and alloys, like steel and titanium. [8]
This device weighed over two and a half pounds and loaded a single 1 ⁄ 2-inch-wide (13 mm) wire staple, which it could drive through several sheets of paper. The first published use of the word "stapler" to indicate a machine for fastening papers with a thin metal wire was in an advertisement in the American Munsey's Magazine in 1901. [4]
4043 aluminium alloy [1] [2] [3] is a wrought aluminium alloy with good corrosion resistance typically used as filler material [4] [5] for welding of aluminium parts. It contains high amounts of silicon (between 4.5 and 6%) and trace amounts of other metals. [6]
