   "A swivel hoist ring bolts into a tapped hole in the load and gives a bail that pivots 180° and swivels 360° for lifting at an angle. Inch rows are the HR-125 UNC sheet exactly as printed (WLL in lb, torque in ft-lb, dimensions in inches, weight in lb); metric rows are the HR-125M sheet (WLL in kg at the 5:1 and 4:1 design factors, dimensions in mm).",
   "Letters: A is the bolt, B the 'effective thread projection length' in the inch sheet; C to H are the sheet's own column letters. Neither sheet defines C to H in text (the drawing is an image), so no letter is interpreted here beyond its position, and in the metric copy the header letters were jumbled in the extracted text, so its columns are given in the order printed (B, C, D, E radius, F diameter, G, H) with the same caveat.",
   "Printed notes: ultimate load is 5 times the WLL (4.5 for the 7000 lb ring at 90°); bolts are Grade 8 alloy socket head cap screws to ASTM A574, long bolts are for soft metal such as aluminium, short bolts for ferrous work pieces only; frame 8 uses a hex head bolt. Torque values are for the supplied bolt. Use the maker's instructions; these are a size reference, not rigging advice.",
   "No file: the body is not defined by published numbers (letters undefined, bail and bushing shapes are not dimensioned), so a model would be invented. The thread is a plain bolt: the 'mating' rows list the thread sizes.",

Torque values are for the supplied bolt. Use the maker's instructions; these are a size reference, not rigging advice.\n- No file: the body is not defined by published numbers (letters undefined, bail and bushing shapes are not dimensioned), so a model would be invented. The thread is a plain bolt: the 'mating' rows list the thread sizes.\n- McMaster-Carr's hoist-ring category is linked for per-part STEP; nothing is copied.\n\nseries  units  frame  WLL  torque (ft-lb)  bolt size A  B  C  D  E  F  G  H  weight each (lb)\nHR-125 UNC  in / lb  1  800  7  5/16 - 18 x 1.50  .58  2.72  .97  .46  .34  1.87  1.12  .37\nHR-125 UNC  in / lb  1  1000  12  3/8 - 16 x 1.50  .58  2.72  .97  .46  .34  1.87  1.05  .39\nHR-125 UNC  in / lb  2  2500  28  1/2 - 13 x 2.00  .70  4.85  1.96  .87  .69  3.35  2.29  2.33\nHR-125 UNC  in / lb  2  2500  28  1/2 - 13 x 2.50  1.20  4.85  1.96  .87  .69  3.35  2.29  2.36\nHR-125 UNC  in / lb  2  4000  60  5/8 - 11 x 2.00  .70  4.85  1.96  .87  .69  3.35  2.16  2.41\nHR-125 UNC  in / lb  2  4000  60  5/8 - 11 x 2.75  1.45  4.85  1.96  .87  .69  3.35  2.16  2.47\nHR-125 UNC  in / lb  2  5000  100  3/4 - 10 x 2.25  .95  4.85  1.96  .87  .69  3.35  2.04  2.52\nHR-125 UNC  in / lb  2  5000  100  3/4 - 10 x 2.75  1.45  4.85  1.96  .87  .69  3.35  2.04  2.59\nHR-125 UNC  in / lb  3  7000 (4.5:1 tested at 90°)  100  3/4 - 10 x 2.75  .89  6.57  2.96  1.36  .94  4.87  2.97  6.72\nHR-125 UNC  in / lb  3  7000 (4.5:1 tested at 90°)  100  3/4 - 10 x 3.50  1.64  6.57  2.96  1.36  .94  4.87  2.97  6.81\nHR-125 UNC  in / lb  3  8000  160  7/8 - 9 x 2.75  .89  6.57  2.96  1.36  .94  4.87  2.84  6.84\nHR-125 UNC  in / lb  3  8000  160  7/8 - 9 x 3.50  1.64  6.57  2.96  1.36  .94  4.87  2.84  6.96\nHR-125 UNC  in / lb  3  10000  230  1 - 8 x 3.00  1.14  6.57  2.96  1.36  .94  4.87  2.72  7.09\nHR-125 UNC  in / lb  3  10000  230  1 - 8 x 4.00  2.14  6.57  2.96  1.36  .94  4.87  2.72  7.31\nHR-125 UNC  in / lb  4  15000  470  1-1/4 - 7 x 4.50  2.21  8.72  3.71  1.75  1.19  6.18  3.93  14.51\nHR-125 UNC  in / lb  5  24000  800  1-1/2 - 6 x 6.75  2.73  12.55  4.71  2.39  1.75  8.48  5.52  37.73\nHR-125 UNC  in / lb  5  30000  1100  2 - 4-1/2 x 6.75  2.73  12.55  4.71  2.39  1.75  8.48  5.02  40.69\nHR-125 UNC  in / lb  6  50000  2100  2-1/2 - 4 x 8.0  4.00  16.88  5.75  3.00  2.25  11.00  8.03  88.00\nHR-125 UNC  in / lb  7  75000  4300  3 - 4 x 10.5  5.00  19.50  7.25  3.75  2.75  14.16  8.50  166.00\nHR-125 UNC  in / lb  8  100000  5100  3-1/2 - 4 x 13.0 (hex head bolt)  7.00  22.09  7.75  4.00  3.25  15.91  9.28  265.00\nHR-125M metric  mm / kg  1  400 (5:1); 500 (4:1)  —  M8x1.25x40  16.9  69.9  24.6  11.8  8.5  47.5  29.9  —\nHR-125M metric  mm / kg  1  450 (5:1); 550 (4:1)  —  M10x1.50x40  16.9  69.9  24.6  11.8  8.5  47.5  28.1  —\nHR-125M metric  mm / kg  2  1050 (5:1); 1300 (4:1)  —  M12x1.75x50  16.9  123  49.8  22.3  17.5  85.1  60.4  —\nHR-125M metric  mm / kg  2  1900 (5:1); 2400 (4:1)  —  M16x2.00x60  26.9  123  49.8  22.3  17.5  85.1  56.3  —\nHR-125M metric  mm / kg  2  2150 (5:1); 2700 (4:1)  —  M20x2.50x65  31.9  123  49.8  22.3  17.5  85.1  52.3  —\nHR-125M metric  mm / kg  3  3000 (5:1); 3750 (4:1)  —  M20x2.50x75  27.8  167  75.2  34.7  25.4  124  76.6  —\nHR-125M metric  mm / kg  3  4200 (5:1); 5250 (4:1)  —  M24x3.00x80  32.8  167  75.2  34.7  25.4  124  70.5  —\nHR-125M metric  mm / kg  4  7000 (5:1); 8750 (4:1)  —  M30x3.50x120  61.7  222  94.2  44.5  30.5  157  102  —\nHR-125M metric  mm / kg  5  11000 (5:1); 13750 (4:1)  —  M36x4.00x150  54.0  318  120  60.7  44.5  215  142  —\nHR-125M metric  mm / kg  5  12500 (5:1); 15600 (4:1)  —  M42x4.50x160  64.0  318  120  60.7  44.5  215  136  —\nHR-125M metric  mm / kg  5  13500 (5:1); 16900 (4:1)  —  M48x5.00x160  74.0  318  120  60.7  44.5  215  130  —\n\nFiles elsewhere (not hosted by Xem Studio; license as stated by the publisher):\n- The Crosby Group: HR-125 UNC swivel hoist rings: frame size, stock number, WLL, torque, bolt size A, B to H, weight (catalogue sheet 9999525) — web — Maker data sheet; numbers only.
