ASME B18.15 pdf download Forged Eyebolts
This Standard is limited to dimensions and capacitiesfor carbon steel and corrosion-resistant stainless steel,forged threaded eyebolts intended primarily for liftingapplications.For carbon steel construction, the sizes arelimited to ‘/4 in. through 2hin., and for corrosion-resistant stainless steel construction, the sizes are limitedto 1’/4 in. through 1/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 informationon the application of eyebolts. NonmandatoryAppendix Dprovides information on eyebolts with met-ric threads M6 through M64 and corresponding materialand performance information.
The inclusion of dimensional data in this Standard isnot intended to imply that all products described arestock production items.Consumers should consult withsuppliers concerning availability of products.
COMPARISON WITH lSo DOCUMENTS
There is no comparable ISO standard for inch eyebolts.ISO 3266, Forged steel eyebolts grade 4 for general liftingpurposes, includes information for metric dimensionedeyebolts.

All dimensions in this Standard are in inches, unlessotherwise stated.
Threads shall be plain finished unified inch coarseClass 2A in accordance with ASME B1.1.Plated or coatedthreads 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 onSystem 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.
7.1 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.
8.1.1 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.
