Conical spring washers DIN 6796, M2–M125: bore, outside diameter, thickness, height, load to flat + 10 cone models — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/conical-spring-washers-din-6796/ (sheet CC BY 4.0) Basis: fasten.it's DIN 6796 table (08/2009 edition, M2 to M125) checked against Westfield Fasteners (M2 to M30, with tolerance classes) and a Böllhoff stainless data sheet (M3 to M16); ten revolved cones as files Catalog version: 2026-10-20 Overall (mm): length 56.0, width 56.0, height 7.75 - Millimetres. DIN 6796 conical spring washers for bolted connections (the 08/2009 edition supersedes 10/1987). fasten.it prints the bore as 'd' and the outside diameter as 'd1' without defining them; Westfield names the bore d1 (class H14) and the OD d2 (class h14). Both give the same numbers. Columns here: bore, OD, thickness s, free height h min / max, approximate load to flat (N, fasten.it only; Westfield's page has no force column) and approximate mass in kg per 1000 pieces. - Agreement: fasten.it and Westfield give identical bore, OD and h for M2 to M30; Böllhoff's stainless sheet agrees on d1, d2, s and h for M3, 3.5, 4, 5, 6, 8, 10, 12, 14 and 16. One difference: for M7 fasten.it prints s 1.8, Westfield 1.75 (M7 has no file). fasten.it prints a 37.2 bore for M36, which Westfield's page does not reach. The load column is as printed by fasten.it and is not a spring rate. - DIN 6796 is a single-cone washer for taking up play and keeping preload in bolted joints; it is not the DIN 2093 Belleville disc spring (see disc-springs-din-2093, which has load-deflection series). Wave forms: wave-spring-washers-din-137. - Files: a plain revolved cone with the published bore, OD and thickness s, drawn at the maximum free height h (inner edge up). h min / h max are printed as a range, so the file shows the upper limit only; no chamfers, radii or edge rounding are published as numbers. Böllhoff (maker) sells these with CAD per article; linked, not copied. size bore d1, H14 (mm) OD d2, h14 (mm) thickness s (mm) height h min / max (mm) load to flat (N, fasten.it) mass (kg / 1000, fasten.it) note M2 2.2 5 0.4 0.5 / 0.6 628 0.05 M2.5 2.7 6 0.5 0.61 / 0.72 946 0.09 M3 3.2 7 0.6 0.72 / 0.85 1320 0.14 M3.5 3.7 8 0.8 0.92 / 1.06 2410 0.25 M4 4.3 9 1 1.12 / 1.3 3770 0.38 M5 5.3 11 1.2 1.35 / 1.55 5480 0.69 M6 6.4 14 1.5 1.7 / 2 8590 1.43 M7 7.4 17 1.8 2 / 2.3 11300 2.53 Westfield prints s 1.75 (fasten.it 1.8) M8 8.4 18 2 2.24 / 2.6 14900 3.13 M10 10.5 23 2.5 2.8 / 3.2 22100 6.45 M12 13 29 3 3.43 / 3.95 34100 12.4 M14 15 35 3.5 4.04 / 4.65 46000 21.6 M16 17 39 4 4.58 / 5.25 59700 30.4 M18 19 42 4.5 5.08 / 5.8 74400 38.9 M20 21 45 5 5.6 / 6.4 93200 48.8 M22 23 49 5.5 6.15 / 7.05 113700 63.5 M24 25 56 6 6.77 / 7.75 131000 92.9 M27 28 60 6.5 7.3 / 8.35 154000 113 M30 31 70 7 8 / 9.2 172000 170 M33 34 76 7.5 8.5 / 10 226000 214 M36 37.2 83 8 9.2 / 10.5 276000 271 M42 43.5 96 8.5 10.5 / 12 290000 384 M48 49.5 110 9 11 / 12.5 261000 535 M56 58 128 9.5 12 / 13.5 260000 762 M64 66 136 10 12.8 / 14 277000 871 M72 74 145 10.5 13 / 15 327000 1007 M90 92.5 160 11 14 / 16 378000 1155 M100 102.5 180 11.5 15 / 17 370000 1552 M125 128 220 12 16.5 / 19 365000 2367 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - fasten.it: DIN 6796 conical spring washers for bolted connections, 08/2009: thread size, bore, OD, thickness s, height h min / max, load to flat, mass (M2 to M125) — web — Reference page; numbers only.
