2.3 Body Diameters

This Standard prov ides for two styles of body diameters. Bolts shall be provided with a full size body in accordance with the

respective table dimensioas of Table 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 ksa than the minimum pitch diameter of the thread and not exceeding the minimum body

diametet E, shown in Table I 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

extrem 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 Inch Series, Class 2A ssspecilied in respective dimensional tables in ASME Bl.l.

2.5.1 Thread Acceptance Gaging. Unless otherwise specified. dimensional acceptability of screw threads shall be determined based on System 21, ASME Bl.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 +0.1H7 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 24 threads for sizes up to and Including tin, and 3’2 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 distance is to be determined by measuring how far the point enters into a cylindrical NOT GO major diameter ring gage.
