Handy chart for converting metric screw sizes to imperial. Engineering Forum Do not use these values for standard metric internal thread design. ISO 261:1973 ISO general purpose metric screw threads - General plan; ISO 262:1973 ISO general purpose metric screw threads - Selected sizes for screws, bolts and nuts; ISO 724:1993 ISO general-purpose metric screw threads - Basic dimensions; ISO 965-1:1980 ISO general purpose metric screw … These are the M Profile limiting Dimensionings. The following table chart defines standard metric external thread size M1.6 to M18 per. to coating. , Ryffel H.H., (2012) . Metric external thread dimensions are given in the external thread chart below according to ASME B1.13M standard. { Metric clearance hole chart for metric bolts and screws according to ASME B18.2.8 The chart below provides information on machine screw sizes from size 000 to ½ inch diameter (past size 12, screws are called by their measurements in inches). ; Metric Grease Fittings; Studs. The designation of a screw thread gives H = P ( 31/2 / 2 ) = 0.866025 P or 0.125H = 0.108253P, Engineering Slide Chart ANSI Screw & Hardware Selector, (adsbygoogle = window.adsbygoogle || []).push({}); Downloads major diameter are same, it is not necessary to repeat the symbols. Imperial To Metric Screw Conversion Chart Those of us of a certain age still refer to screw sizes as imperial – we often hear the words can I have a box of 1”x 8’s please? For those with a diameter smaller than 1/4", screw size is indicated by a number (e.g., #10 or No.10). Excel App. Print this page . The same as in the imperial system, the length is measured in millimeters. As you can imagine, the metric system is a little simpler to understand for the uninitiated however if you’re not used to it, or still working in Imperial it can be a little tricky. All units in mm. General Note: All dimensions are in millimeters. document.write('

'); Sequences like "4-30 x .10," "1/8-10 x 4/6" and "M5-.4 x 15" may seem meaningless, but they say a lot, and you need the right screw to do the job. Special order screws are available in size M0.6 and up.
