DEFINITIONS. The diameter equal to the external diameter of the threads or the overall diameter of the part. (Nominal diameter is more of a label than a size. For example, a bolt and nut may be described as being ½" diameter. But neither the external threads of the bolt nor the internal threads of the nut are exactly .500 in diameter.

1/2 in.-13 x 1-1/2 in. Galvanized Hex Bolt Hex bolts are hexagonal head fasteners with Hex bolts are hexagonal head fasteners with machine threads. They are commonly used for machinery and construction projects, both residential and commercial. Fully threaded sizes provide excellent grip strength.

Here, this bolt has a tensile strength of 1,000MPa (145,000PSi) and a yield strength of 900MPa (130,000PSi). Bolt Size Chart. Let us now see some bolt size charts. We will see both imperial and metric charts for bolt dimensions as well as the thread pitch. 1/2: 13: 20. 9/16. 12: 18: 5/8: 11: 18. 3/4. 10: 16: 7/8: 9: 14. 1. 8: 14: 1-1/8: 7: 12.

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.

Standard metric threads, meaning ISO metric threads in this case, ASTM bolt standards and other fasteners almost always appear as

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.

Unlike metric fasteners, a larger number indicates a finer thread (that's because threads per inch is the reciprocal of pitch). Common threads per inch sizes 

Bolts are generally made slightly smaller than their nominal diameter for ease of installation. Here we have a 3/8 inch bolt, and as you can see 

The 1/4″ refers to the bolt diameter (in inches), the -20 refers to the threads per inch meaning that there are 20 threads per inch on this
