2009. 9. 22. · The first technician is correct, it is a coarse thread. I'm not sure there is a bolt called 12-13 so I am assuming you meant 1/2 - 13. Wich would be a bolt 1/2 inches long. The

Metric Bolt Conversion. Metric bolt conversion data for industrial bolts/rods , machine screws and small diameter fasteners from Raaj Sagar Steels includes metric to standard bolt conversions. The chart below shows metric bolt conversions and DIN numbers for fasteners.

For example, a bolt labeled M10 x 1.5 is a metric bolt with a 10 mm diameter and 1.5 mm between threads. Thread Size Chart. Thread fit categorizes the tolerances between the peaks and valleys (crests and roots) of mating threaded hardware. In metric descriptions, 1/2. 13. 20. 28.

2-4 1/2 x 8 Hex Bolt. This bolt has a hex head, is 2 inches in diameter, has 4 1/2 threads to the inch, and is 8 inches long. Use a 2-4 1/2 nut with this bolt. Following are just some of the more popular sizes (diameter-threads per inch) of machine and caps screws and other fasteners Fastener Mart sells. Table 3.

2021. 10. 26. · Thread Length. Thread Pitch. The diameter of the Bolt is the actual size of the bolt and it is measured across the bolt shank or the threaded area. The body length of the bolt is measured from the tip of the bolt to the point where the shank meets the head. If the bolt is partially threaded, then the thread length can also be measured.

The Grade 5 bolt can be distinguished by the 3 dashes (l) on top of the head of the bolt, please see photo below. A Grade 5 hex bolt has greater tensile strength than a Grade 2 hex bolt. The length of a hex bolt is determined by measuring from under the head of the bolt to the base of the threads. Please note you are buying by the pound so

Answer (1 of 4): Seems like an incomplete spec to me. Normally a metric sized fastener would be a hex head bolt is described Mdd - pp x LL M means metric; dd is the full millimeter diameter of the threaded shank; and pp is the pitch in millimeters; and

The latter is also commonly referred to as threads per inch (TPI) or thread pitch. We use the TPI to determine the thread's fineness. The number will also tell if a screw can thread through a bolt. To measure screw size, we take its diameter. If the measurement says 1/4-20, it means it has a diameter of 1/4 inch and 20 threads per inch.

Choose from our selection of 1/2"-13 taps, including over 80 products in a wide range of styles and sizes. However, a longer taper means that they cannot thread as close to the bottom of closed-end holes. Their bottoming chamfer has 1-2 chamfered cutting threads, so they can thread holes closer to the bottom than other taps.
