1 SCOPE This Standard is limited to dimensions and capacities for carbon steel and corrosion-resistant stainless steel, forged threaded eyebolts intended primarily for lifting applications. For carbon steel construction, the sizes are limited to 1 ⁄ 4 in. through 2 1 ⁄ 2 in., and for corrosion- resistant stainless steel construction, the sizes are limited to 1 ⁄ 4 in. through 1 1 ⁄ 2 in. This Standard covers the follow- ing types and styles: (a) Type 1, plain pattern (straight shank) (see Table 1) (1) Style A, long length (2) Style B, short length (b) Type 2, shoulder pattern (see Table 2) (1) Style A, long length (2) Style B, short length Nonmandatory Appendices A and B contain descrip- tive and cautionary information pertinent to forged eye- bolts. Nonmandatory Appendix C contains information on the application of eyebolts. Nonmandatory Appendix D provides information on eyebolts with met- ric threads M6 through M64 and corresponding material and performance information. The inclusion of dimensional data in this Standard is not intended to imply that all products described are stock production items. Consumers should consult with suppliers concerning availability of products. 2 COMPARISON WITH ISO DOCUMENTS There is no comparable ISO standard for inch eyebolts. ISO 3266, Forged steel eyebolts grade 4 for general lifting purposes, includes information for metric dimensioned eyebolts. 3 REFERENCED STANDARDS ASME B1.1, Unified Inch Screw Threads (UN and UNR Thread Form) ASME B1.3, Screw Thread Gaging Systems for Acceptability — Inch and Metric Screw Threads (UN, UNR, UNJ, M, and MJ) ASME B1.16M, Gages and Gaging for Metric M Screw Threads ASME B18.12, Glossary of Terms for Mechanical Fasteners ASME B18.18, Quality Assurance for Fasteners ASME B30.26, Rigging Hardware Publisher: The American Society of Mechanical Engineers (ASME), Two Park Avenue, New York, NY 10016-5990 (www.asme.org) ASTM A380, Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment, and Systems ASTM A473, Stainless Steel Forgings ASTM A489, Carbon Steel Eyebolts ASTM F541, Alloy Steel Eyebolts ASTM F606, Determining the Mechanical Properties of Externally and Internally Threaded Fasteners, Washers, Direct Tension Indicators, and Rivets ASTM F788/F788M, Surface Discontinuities of Bolts, Screws, and Studs, Inch and Metric Series ASTM F1941, Electrodeposited Coatings on Threaded Fasteners [Unified Inch Screw Threads (UN/UNR)] Publisher: American Society for Testing and Materials (ASTM International), 100 Barr Harbor Drive, P.O.

Plated or coated threads shall conform to the maximum limit of Class 3A (GO) and the minimum limit of Class 2A (NOT GO). Unless otherwise specified, the dimensional accept- ability of screw threads shall be determined based on System 21 of ASME B1.3.
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 tempera- ture applications to −40°F (−40°C) shall be in accordance with ASTM F541. ASTM A489 and ASTM F541 eyebolts shall be 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 are 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 accor- dance 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 (f) material (including standard), including alloy type if stainless steel (g) surface treatment (when specified including stan- dard number), including required callout from standard EXAMPLE: ASME B18.15, 3 ⁄ 8 -16, plain pattern (straight shank), Type 1, Style A, steel per ASTM A489, zinc plated per ASTM F1941 5AT 10 QUALITY ASSURANCE 10.1 Defects Eyebolts shall be free from visible defects that might affect serviceability. Eyebolts should be routinely visually inspected for such defects according to ASME B18.18. 10.2 Dimensional Conformance Unless otherwise specified, all characteristics shall be inspected to the inspection levels shown in ASME B18.18. 10.3 Tensile Properties The tensile properties shall be determined in accor- dance with ASTM F606 using the thread engagements as prescribed in Nonmandatory Appendix C. 10.4 Surface Discontinuities The inspection and evaluation of surface discontinu- ities 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 eyebolt shall have the manufacturer’s name or identification mark forged in raised characters on the surface of the lifting eye.
