The University Corporation for Atmospheric Research publishes a wire gauge chart on its website. The chart shows average wire gauges along with current limits for each gauge along with maximum amps for chassis wiring and maximum amps for power transmission. For simplicity's sake, the chart features
The Engineering ToolBox and Maryland Metrics are two organizations that have charts showing pipe thread sizes on their websites. Common American national standard pipe taper threads are the NPT and NPTF, says The Engineering ToolBox.
When reading a needle gauge chart, a higher needle gauge is associated with a thinner the needle size, according to Becton Dickinson Diagnostics. Needle size get smaller as you move down the chart.
The information on a bolt thread-size chart varies depending on its type, but dimensions and thread count are basic data that are always included. The easiest charts for identifying dimensions are layover charts that show full-size outlines and list unique characteristics of each.
A sheet steel gauge chart is a chart or table that compares the standard or average weight and thicknesses of different steels and metals in both sheet and wire form.
Size six ear gauges are considered to be larger than average. Most earlobes are initially pierced with an 18- or 20-gauge needle. Gauge sizes typically range between size 20 and 00, with 00 being the largest.
Metric thread charts contain information regarding the internal and external diameter of the bolt or nut, the thread's spacing and the thread's minimum and maximum pitch. It also contains the ISO metric thread profile.
The Coats website provides downloadable shade cards for each of the cotton threads in its range. There is a different shade card for each type and length of thread. Coats makes three-ply all purpose, machine-quilting and hand-quilting threads in lengths of either 225, 350 or 1200 yards.
Headings on a thread pitch chart include thread class, the fit when a screw is being placed in an also-threaded part; major and minor diameter; and pitch diameter, the point where the width of thread and space between threads is equal. Screw dimensions vary based on the intended use.
UNJF thread charts describe dimensions for fasteners adhering to the Unified Thread Standard. Typical dimensions on a UNJF thread chart include thread standard, pitch, diameter and tolerance. A UNJF thread chart may also include applicable standards based on fastener.
