ASME B18.10:2006 pdf free download.Track Bolts and Nuts.
ASME B18.10 covers the complete general and dimensional data for inch series oval neck and elliptic neck track bolts and square nuts intended for use with these bolts, and recognized as an American National Standard. Sizes in use, but not recommended for new design, are included in the appendices of this Standard.
1.2 Comparison to ISO Standards
There is no ISO standard for these products at this time.
1.3 DimensIons
The inclusion of dimensional data in this Standard is not intended to imply that all of the products described herein are stock production sizes. Purchasers should consult with suppliers concerning lists of stock production sizes.
All dimensions in this Standard are in inches, unless otherwise stated, and apply to unpiated or uncoated products. When plating or coating is specified, the finished product dimensions shall be as agreed upon between supplier and purchaser.
Definitions of specified geometric characteristics are in accordance with ASME Y14.5M.
1.4 Options
Options, where specified, shall be at the discretion of the manufacturer unless otherwise agreed upon by the manufacturer and tile purchaser.
1.5 TermInology
All terms used in this Standard are defined in ASME
B18.12.
1.6 References
Unless otherwise specified, the referenced standard shall be the most recent issue at the time of order placement.

2.2 Necks
Types of track bolts arc designated as “oval neck” and “elliptic neck.”
2.3 Body Diameters
This Standard provides for two styles of body diameters. Bolts shall be provided with a full size body in accordance with the respective table dimensions of Table I 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 bolt length 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 he rolled unless otherwise agreed to between the purchaser and the supplier.
Threads shall be Unified Inch Series, Class 2A as specified in respective dimensional tables in ASME 81.1.
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, LT, shall be as shown in Tables I and 2. The tolerance on thread length shall be + 0.187 in. or 2.5 X pitch, whichever is greater. Bolts of nominal lengths too short to 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 threads for sizes upto and including I in. and 34 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 distance 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 at Maximum Material Condition (MMC).
