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 ...
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]
ISO 14555 is an ISO standard for arc stud welding of metallic materials.It was incorporated as a European Norm as EN (ISO) 14555 and is referenced by Eurocode 4 in the evaluations of the design shear resistance of a headed stud which is automatically welded according to this standard.
Bostitch was founded in Arlington, Massachusetts in 1896 by Thomas Briggs as the Boston Wire Stitcher Company. Briggs had invented a machine that stitched books from a coil of wire. The company began manufacturing various other kinds of staplers for industrial use. [4] It largely focused on commercial stitching machines.
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.
This is a list of welding processes, separated into their respective categories.The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063). [1]
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 ...
Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...
