ASME B18.10 pdf download Track Bolts and Nuts
2.2 Necks Types of track bolts are designated as “oval neck” and “elliptic neck.”
2.3 Body Diameters This Standard provides for two styles of body diame- ters. Bolts shall be provided with a full size body in accordance with the respective table dimensions ofTable 1 or 2 for body diameter, E, unless a reduced body diameter is specified on the purchase order. These shall have a body diameter not less than the minimum pitch diameter of the thread and not exceeding the minimum body diameter, E, shown in Table 1 or 2.
2.4 Bolt Length The boltlength shall be the distance measured parallel to the axis of the product from the bearing surface of the head to the extreme end of the bolt, including the point if the product is pointed.
2.5 Threads Bolt threads shall be rolled unless otherwise agreed to between the purchaser and the supplier. Threads shall be Unified InchSeries, Class 2Aas speci- fied in respective dimensional tables in ASME B1.1. 2.5.1 Thread Acceptance Gaging. Unless otherwise specified, dimensional acceptability of screw threads shall be determined based on System 21, ASME B1.3M.
2.6 Thread Length The length of thread shall be measured parallel to the axis of the bolt from the end of the bolt to the last complete (fully formed) thread. The minimum thread length, L T , shall be as shown in Tables 1 and 2. The tolerance on thread length shall be + 0.187 in. or 2.5 ✕ pitch, whichever is greater. Bolts of nominal lengths too shortto accommodate the minimum thread lengths shall be threaded full length. The distance from the neck to the first complete (full form) thread shall not exceed 2 1 ⁄ 2 threads for sizes up to and including1 in. and 3 1 ⁄ 2 threads for sizes over 1 in.
2.7 Pointed Products Unless otherwise specified, bolts need not be pointed. When pointed, the first full formed thread at a major diameter is located at a distance no greater than 2 times the pitch measured from the end of the screw. This ditance is to be determined by measuring how far the point enters into a cylindrical NOT GO major diameter ring gage.
2.8 Straightness Shanks of bolts shall be straight within the following limits atMaximumMaterial Condition(MMC). Forbolts with nominal lengths up to and including 12 in., the maximum camber shall be 0.006 in. per inch (0.006L) of bolt length. For bolts having a full diameter body, a typical gage and gaging procedure for checking bolt straightness is given in Appendix I of ASME B18.2.1. For bolts with an undersized body, the gaging method shall be the sleeve gage shown in Appendix II of ASME B18.2.1.
2.9 Track Bolt Nuts Track bolt nuts shall be dimensionally in accordance with ASME B18.2.2. Selected sizes are included in Table 3.
