The coarse-thread series (UNRC or UNC) is used on the vast majority of bolts and nuts. Number of threads per inch ranges from 20 threads for a 1/4-in.- diameter 

Metric Bolt Thread Size: Thread sizes for coarse and fine pitch thread were created using the standard sizes from ASME B1.13M.

Bolt Torque Chart Suggested Starting Torque Values Notes: Values calculated using industry accepted formula T = KDP where T = torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load (lbs).

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.

Metric bolts are referenced using "M" sizes, such as the M8 bolt size. The size of a metric bolt is specified using pitch, diameter, and length in millimeters. For example, in M8-1.0*20, the "M" means the Metric thread designation, the digit 8 refers to the Nominal diameter (in millimeters), 1.0 refers to the pitch, and 20 refers to the

13. Increased standard bolt hole diameter and slot widths for bolts 1-in. in diameter and greater (Table 3.1). 14. Table 8.1 Minimum Bolt Pretension moved to Table 5.2 in design. 15. Revised values for pre-installation verification testing and for pretension for Group 120 bolts larger than 1 in. diameter (Table 5.2).

High Tensile Bolts Specifications There are many grades available, including 10.9, 8.8, DIN 933, and 12.9 grades. Many other standards exist, including IS1364, IS1363, DIN EN ISO 4014, and others. These standards specify fastener sizes ranging from 20mm to 100mm. The various types, such as the High Tensile Bolt, are used for various purposes.
