6 SHANK LENGTH
Shank length includes the chamfer to the underside of the eye ring for plain pattern (straight shank) and to the faced collar for shoulder pattern eyebolts.
7 MATERIAL
7.1 Carbon and Alloy Steel Forged
The material and mechanical property requirements for general purpose carbon steel eyebolts shall be in accordance with ASTM A489. Eyebolts requiring improved toughness or intended primarily for temperature applications to —40°F (—40°C) shall be in accordance with ASTM FM1. ASTM A489 and ASTM F541 evebolts shall he capable of meeting the rated capacities of Tables 3 and 4,
7.2 Corrosion-Resistant Steel Forged
When corrosion-resistant steel is required, refer to ASTM A473, alloy types 304, 304L or 316, and 316L. Eyebolts of ASTM A473 materials shall be capable of meeting the rated capacities of Tables 3 and 4. The alloy type as listed in ASTM A473 shall be marked on the eyebolt eye.
7.3 Other Materials
When other materials arc required, the material shall be as agreed upon by the purchaser and supplier.
8 FINISH
8.1 Steel
8.1.1 Unless otherwise specified, eyebolts shall be supplied with a natural (as processed) finish, unplated or uncoated, in a clean condition, and lightly oiled.
8.1.2 When zinc plating is specified, ASTM F1941 shall be designated. Other finishes may be used based on an agreement between the purchaser and supplier. (This is not recommended; see para. C-7 in Nonmandatory Appendix C.)
8.2 Corrosion-Resistant Steels
Corrosion-resistant steels shall be passivated in accordance with ASTM A380.
9 DESIGNATiON
Eyebolts shall be designated by the following data in the sequence shown below:
(a) ASME B18.15
(b) nominal size (fractional or decimal equivalent) and threads per inch
(c) pattern
(d) type
(e) style
(1) material (including standard), including alloy type if stainless steel
(g) surface treatment (when specified including standard number), including required callout from standard
EXAMPLE: ASME BIH.15, %-16. plain pattern (straight shank).
Type I. Style A, steel per ASTM A4B9. zinc plated per
ASTM FI941 SAT
10 QUALITY ASSURANCE
10.1 Defects
Eyebolts shall be free from visible defects that might affect serviceability. Eyeholts should he routinely visually inspected for such defects according to
ASME 1318.18.
10.2 Dimensional Conformance
Unless otherwise specified, all characteristics shall be inspected to the inspection levels shown in
ASME 1318.18.
10.3 Tensile Properties
The tensile properties shall be determined in accordance with ASTM F606 using the thread engagemenis as prescribed in Nonmandatory Appendix C.
10.4 Surface Discontinuities
The inspection and evaluation of surface discontinuities shall be in accordance with the requirements in ASTM F788/F788M. Threads shall have no laps at the root or on the flank located below the pitch diameter.
11 MARKING
Each eyebott shall have the manufacturer’s name or identification mark forged in raised characters on the surface of the lifting eye.
A-i INTRODUCTION
Two methods are currently used in specifying the capacities of forged steel eyebolts. One is more commonly used by riggers and shop personnel, while the other is generally preferred by engineers and designers of lifting rigs. Care must be exercised in selecting and using the correct type of capacity for each application.
A-2 RIGGER’S CAPACITY
The rigger’s capacity refers to the actual load a single eyebolt can lift, The allowable load varies with the angle between the leg of the lifting rig and the shank of the eyebolt. In general, it also assumes that the load to be lifted acts along the axis through the shank. (The primary exception is where the eyebolts are mounted on the sides of the load.) Rigger’s capacities are most easily used when the evebolts are mounted on the top of a uniformly distributed load. In such cases, the total load is divided by the number of eyebolts to be used for the lift in order to determine the required capacity, taking into account the angle of the legs of the rig. Figure A-I shows such an application.
15 INSPECTION AND QUALITY ASSURANCE
Unless otherwise specified by the purchaser, inspection of serrated flange locknuts shall be in accordance with ASME B18.18.2M.
16 DESIGNATiON
Serrated hex flange locknuts shall be designated by the following data, preferably in the sequence as follows:
(a) product name and designation of standard (ASME B18.16.4)
(b) nominal diameter and thread pitch
(c) steel property class or material identification, and protective coating, if required.
EXAMPLE: Regular errated flange locknut. ASME B1&16.4. -13, zinc plated per ASTM E 1941 Fe/Zn 3A.
17 OPTIONS
Options, where specified, shall be at the discretion of the manufacturer, unless otherwise agreed between manufacturer and purchaser.
18 WORKMANSHIP
Nuts shall be free of surface irregularities that might affect their serviceability, such as burrs, seams, laps, loose scale, and other irregularities. While control of surface discontinuities is important for the application intended, ASTM F 812 shall be specified by the purchaser.
