T-slot extrusion variants: 1-slot, 2-slot, 3-slot, closed-slot, light, heavy, angled (Misumi HFS F / T / H / C / L / G): mass, area, Ix, Iy — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/t-slot-profile-variants-misumi/ (sheet CC BY 4.0) Basis: Misumi HFS catalog pages (type codes, sizes per series, mass, area and second moments); numbers only Catalog version: 2026-10-20 Sizes: see table below - Type codes as Misumi prints them: four slots: HFS, EFS, NFS, NEFS, GFS, CAF, HFSY; 3-side slot (1 side flat): HFSF, EFSF, NFSF, NEFSF, GFSF; two-side slots (two flats): HFST, EFST, NEFST, GFST; two slots on opposite sides: HFSH, EFSH; one-side slot (three flats): HFSC, EFSC; light type: NFSL, HFSL, HFSLF, HFSLT, HFSLB; heavy type: HFSG; angled: HFS30A, HFS45A, HFS60A; curved: HFSR, NFSR. - T-slot extrusion comes in more than the four-slot square. Misumi's catalog names the arrangements: 3-side slot (one side flat, code F), two-side slots (two flats, T), two slots on opposite sides (H), one-side slot (three flats, C), plus light (L), heavy (G / HFSG) and angled 30 / 45 / 60 degree types. Makers elsewhere call the same things 1-slot, 2-slot adjacent, 2-slot opposite, 3-slot, closed-slot or smooth-face extrusion; the codes below are Misumi's, the words are the catalog's. The first table of numbers is the catalog's type code table; the second is every variant whose mass, area, Ix and Iy were legible. - Ix and Iy are in units of 10^4 mm4 as printed (0.742 means 0.742 x 10^4 mm4). Where the catalog prints one value for the pair (HFSF6-6060 and HFST6-6060 share one row), they are shown as one row. Ix and Iy are in the order the catalog prints them (3060: 5.33 then 20.56); the text read here does not say which axis is which, so check against the drawing before using either in a beam calculation. - Base profile values agree with the existing profile pages: 2020 183 mm2 and 0.5 kg/m, 2040 324 and 0.88, 4040 (5 series) 472 and 1.28, 3030 333 and 0.9, 3060 592 and 1.6, 6060 971 and 2.63, 4545 777 and 2.1, 4590 1534 and 4.14. - What the numbers say about the shape: against the 183 mm2 four-slot 2020, the 3-side type is 195 (+12), two-side 196 (+13), opposite-side 199 (+16) and one-side 208 (+25) mm2. The shape of the flat faces is a drawing, not text, so none is modelled here; take Misumi's CAD for the variant, and use the base profile's files only where the flat face does not matter. - Left out because the table was not readable: the 8 series (40 / 80 mm square, 10 mm slot) F, T, H, C, L and G values (Misumi page not legible), 6 series 6090 / 60120 (one row shared with the economy EFS type), the economy (Misumi Economy Series LCF) 4040 variants (row alignment unclear), 80/20 closed-slot and smooth types (80/20 pages could not be read here), and every 2 x 2 or larger 3-side type except those shown. - Files: none. The dimensioned cross-section drawings of these variants are images; a file drawn from the base profile with a guessed flat face would be wrong in the one place that matters. The base profiles with true-size STEP and STL are the related pages. Misumi's own CAD for each variant is on its product page. series size type code what it is (Misumi wording) mass, kg/m area, mm2 Ix, 10^4 mm4 Iy, 10^4 mm4 5 2020 HFS5 base profile 0.5 183 0.742 0.742 5 2020 HFSF5 3-side slot, 1 side flat 0.53 195 0.834 0.746 5 2020 HFST5 two-side slots, two flats — 196 0.808 0.808 5 2020 HFSH5 two slots on opposite sides — 199 0.74 0.89 5 2020 HFSC5 one-side slot, three flats 0.56 208 0.81 not legible 5 2040 HFS5 base profile 0.88 324 1.358 5.13 5 2040 HFSF5 3-side slot, 1 side flat 0.93 344 1.52 5.40 5 4040 (2 x 2 cells, 5 series) HFS5 base profile 1.28 472 8.89 8.89 5 4040 (2 x 2 cells, 5 series) HFSF5 3-side slot, 1 side flat 1.41 522 9.78 9.32 5 4040 (2 x 2 cells, 5 series) HFST5 two-side slots, two flats 1.35 497 9.60 9.60 6 3030 HFS6 base profile 0.9 333 2.83 2.83 6 3030 HFSL6 light type 0.76 280 2.68 2.68 6 3030 GFS6 high rigidity (heavier wall) 1.02 377 3.47 3.47 6 3030 HFSF6 3-side slot, 1 side flat 0.92 338 3.03 2.76 6 3030 HFST6 two-side slots, two flats 0.95 351 3.03 not legible 6 3030 HFSH6 two slots on opposite sides 0.93 345 2.69 3.23 6 3030 HFSC6 one-side slot, three flats 0.97 361 2.99 3.24 6 3060 HFS6 base profile 1.6 592 5.33 20.56 6 3060 HFSL6 light type 1.29 476 4.87 17.87 6 3060 GFS6 high rigidity 1.71 634 5.95 23.78 6 3060 HFSF6 3-side slot, 1 side flat 1.67 616 5.81 20.93 6 3060 HFST6 two-side slots, two flats 1.68 624 5.93 23.01 6 3060 HFSH6 two slots on opposite sides 1.73 642 6.36 21.41 6 3090 HFS6 base profile 2.44 902 8.44 66.28 6 30120 HFS6 base profile 3.21 1188 11.19 152.2 6 5050 HFS6 base profile 2.32 857 21.60 21.60 6 5050 HFSL6 light type 2.05 760 18.79 18.79 6 5050 HFSF6 3-side slot, 1 side flat 2.32 861 22.23 21.40 6 5050 HFST6 two-side slots, two flats 2.36 874 22.26 22.26 6 50100 HFS6 base profile 4.36 1614 42.40 153.5 6 6060 HFS6 base profile 2.63 971 41.4 41.4 6 6060 HFSG6 heavy type 4.13 1529 54.2 54.2 6 6060 HFSF6 and HFST6 (one row in the source) 3-side slot / two-side slots 2.73 1011 43.8 43.8 6 100100 HFS6 base profile 5.52 2043 265.2 265.2 6 606030 HFS6 base profile 2.33 864 27.3 27.3 6 30 (angled) HFS30A6-30 30 degree angled profile 1.11 412 3.15 3.86 6 30 (angled) HFS45A6-30 45 degree angled profile 1.08 401 3.21 3.72 6 30 (angled) HFS60A6-30 60 degree angled profile 1.1 410 3.33 3.70 8 / 8-45 40 (angled, 8 series) HFS30A8-40 30 degree angled profile 1.88 694 9.89 10.64 8 / 8-45 40 (angled, 8 series) HFS45A8-40 45 degree angled profile 1.83 676 9.87 10.37 8 / 8-45 40 (angled, 8 series) HFS60A8-40 60 degree angled profile 1.84 679 9.99 10.53 8 / 8-45 4545 (8-45 series) HFS8 base profile 2.1 777 15.13 15.13 8 / 8-45 4545 (8-45 series) HFSL8 light type 1.7 628 11.73 11.73 8 / 8-45 4545 (8-45 series) GFS8 high rigidity 3.16 1171 23.64 23.64 8 / 8-45 4545 (8-45 series) HFSF8 3-side slot, 1 side flat 1.97 730 13.88 14.58 8 / 8-45 4545 (8-45 series) HFSLF8 light type, 3-side slot 1.6 590 10.88 11.33 8 / 8-45 4545 (8-45 series) GFSF8 high rigidity, 3-side slot 3.16 1172 24.54 23.36 8 / 8-45 4590 (8-45 series) HFS8 base profile 4.14 1534 32.29 124.7 8 / 8-45 4590 (8-45 series) HFSL8 light type 2.98 1101 22.87 87.16 8 / 8-45 4590 (8-45 series) GFS8 high rigidity 5.22 1935 42.99 163.4 8 / 8-45 4590 (8-45 series) HFSF8 3-side slot, 1 side flat 3.8 1408 30.92 116.8 Files elsewhere (not hosted by Xem Studio;
