ASME B18.31.5 pdf download.Bent Bolts(Inch Series).
1.1.1 ASME B18.31.5 establishes general requirements for parts classified as bent bolts. Dimensional requirements are provided in tables for U-bolts of differing bends, eyebolts, hook bolts of differing bends, and I-bolts. General requirements are provided for offset round bend. I-bolts, square bend hook bolts, vee bend U-bolts, and slant U-bolts.
1.1.2 Two methods are identified for designating (ordering) bent bolts covered by this Standard. For configurations covered by dimensional tables, Nonmandator Appendix A provides a Part Identification Number(PIN) system that allows ordering the parts in several materials and finishes. For configurations without dimensional requirements or of sizes not covered in the tables, a standard system for identifying the dimensions, material, and finish is provided.
1.1.3 The inclusion of dimensional data in this Standard reflects generally available configurations It is not intended to imply that all of the products described herein are stock production sizes, particularly in materiaLs other than low carbon steel. Consumers should consult with manufacturers concerning lists of stock production sizes and materials.
1.2 Dimensions
All dimensions in this Standard are in inches, unless otherwise specified. When plating or coating is specified, the finished product dimensions apply before plating or coating unless otherwise specified by the purchaser.
1.3 Options
Options, where specified, shall be at the discretion of the manufacturer, unless otherwise agreed upon by the manufacturer and the purchaser.
1.4 Terminology
The following terms used in this Standard are identified in this Standard below or in para. 2.1. The definition of other terms used in this Standard may be found in
ASME B18.12.
1.4.1 L-hook bolt is also known as a hook bolt, right angle bend as defined in ASME B18.12.
A-I PART IDENTiFYING NUMBERS (PINS) FOR SftECTED BENT BOLTS
PINs are provided herem for selected bent bolts for common logistics identification among designers, fastener manufacturers, construction and repair activities, and equipment operators. PINs are required for military applications and provide a concise method of identifying parts in all applications. PINs are provided for only those bent bolts of configurations and materials most commonly used. For part configurations and materials not covered, an alternate method of identifying parts is identified in this Standard. Bolts with different dimensions will be considered for addition in future revisions. Inclusion in this Standard does not guarantee availability.
A-2 ThE PIN SYSTEM
Figure A-I illustrates the PIN system. The system consists of seven fields in the order identified in Fig. A-I. There are no blank spaces in the PIN. The two-digit number for Field 3, the diameter of the bolt, and Field 5, representing other dimensional characteristics, are found in the dimensional table for the applicable bent bolt configuration. The Field 3 diameter is generally the diameter in sixteenths of an inch. Although Field 5 represents all the remaining dimensions of the applicable bolt, it is generally the length of the bolt in tenths of an inch. For example, 027 would represent a length of 2.75 in. If another bolt is of the same diameter and general configuration with the same length but a different width, it may be designated by 028.
A-2.1 PIN Coverage for Additional Lengths
For some configurations as indicated in the tables, the l’IN field permits lengths other than those listed as standard to be designated.
A-2.2 Identification of Materials and Finishes
Table A-i identifies materials covered by the PIN system with a two-character field. Table A-2 identifies finishes covered by the PIN with a three-character field, although use of the second and third characters is optional.
A-3 IDENTIFICATION OF PART NUMBERING SYSTEM ON DRAWINGS
On drawings or parts lists where a column exists for identifying the manufacturer or its Commercial and Government Entity Code, indicate the CAGE Code “05047/B18.31.5” or “ASME B18.31.5.” If no column exists or there is space only for the five-digit CAGE Code, then a note must indicate that the part numbers are defined in ASME B18.3l.5.
