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.
9DESIGNATION
Eyebolts shall be designated by the following data inthe 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 typeif stainless steel(g) surface treatment (when specified including stan-dard number), including required callout from standardEXAMPLE: ASME B18.15,%-16, plain pattern (straight shank),Type 1,Style A,steel per ASTM A489,zinc plated perASTM 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 accordance with ASTM F606 using the thread engagements 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 eyebolt shall have the manufacturer’s name or identification mark forged in raised characters on the surface of the lifting eye.
