Metric hex socket set screws by point type: flat, cone, dog and cup (ISO 4026, 4027, 4028, 4029 / DIN 913–916), M1.6–M24 incl. M10 and M12 — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/set-screws-metric-m10-m12-and-point-types/ (sheet CC BY 4.0) Basis: fasten.it reprints of DIN EN ISO 4026 / 4027 / 4028 / 4029 (05-2004) and Westfield's ISO 4026 / DIN 913 table (s max / min, dp min, t min by length); mm; numbers only Catalog version: 2026-10-20 Sizes: see table below - The four ISO point forms: ISO 4026 flat point (DIN 913), ISO 4027 cone point (DIN 914), ISO 4028 dog point (DIN 915), ISO 4029 cup point (DIN 916). All share the same thread, hex socket (s nom) and socket width across corners; they differ only in the point. The fasten.it tables label every point diameter 'd1 max'; Westfield's table and AmesWeb's headings name them dp (flat and dog), dt (cone) and dz (cup), and this table does the same. - Hex key: M10 5 mm, M12 6 mm (s nom), with s max / min printed by Westfield (M10 5.14 / 5.020, M12 6.14 / 6.020). Socket depth t min is given for the shortest lengths and for other lengths (Westfield: M10 4 and 6 mm, M12 4.8 and 8 mm); the fasten.it tables print it as a range (M10 4 ÷ 6, M12 4.8 ÷ 8) and the length threshold between the two is not printed on either page. - Point sizes, M10 / M12: flat dp max 7.00 / 8.50 (dp min 6.64 / 8.14); cone dt max 2.5 / 3; dog dp max 7 / 8.5, dog length z max / min 2.75 / 2.5 and 3.25 / 3 for short screws and 5.3 / 5 and 6.3 / 6 for long screws; cup dz max 6 / 8 mm. 'Short' and 'long' are the fasten.it column labels; the length at which a dog point is 'long' is not printed on that page. - Commercial lengths: the cone, dog and cup mass tables print M10 at 10, 12, 16, 20, 25, 30, 35, 40, 45, 50, 55, 60 mm and M12 at 12, 16, 20, 25, 30, 35, 40, 45, 50, 55, 60 mm (identical for the three). MRO Supply lists metric dog-point screws M4 to M12 in lengths 5 to 40 mm, so stock ranges are shorter than the standard's. Property class 45H, thread tolerance 6g (AmesWeb). - Existing page: set-screws-metric covers the flat-point M3–M8 files; socket-set-screws-inch-asme-b18-3 is the inch family. No files here: the point angles (the chamfer on a flat point, the cone angle, the cup shape) are not in the tables read, so a point cannot be drawn from published numbers and a set screw without a point would be a plain cylinder. The page is a full numbers table instead. One typo-looking value on the fasten.it dog-point mass table (M2 at 3 mm: 0.53) is not used. thread pitch (mm) s hex key nom s max / min e socket across corners min t min: shortest l / other l ISO 4026 flat dp max / min ISO 4027 cone dt max ISO 4028 dog dp max dog z short max / min dog z long max / min ISO 4029 cup dz max M1.6 0.35 0.7 0.724 / 0.710 0.809 0.7 / 1.5 0.80 / 0.55 0.4 0.8 0.65 / 0.4 1.05 / 0.8 0.8 M2 0.4 0.9 0.913 / 0.887 1.011 0.8 / 1.7 1.00 / 0.75 0.5 1 0.75 / 0.5 1.25 / 1 1 M2.5 0.45 1.3 1.300 / 1.275 1.454 1.2 / 2 1.50 / 1.25 0.65 1.5 0.88 / 0.63 1.5 / 1.25 1.2 M3 0.5 1.5 1.58 / 1.520 1.73 1.2 / 2 2.00 / 1.75 0.75 2 1 / 0.75 1.75 / 1.5 1.4 M4 0.7 2 2.08 / 2.020 2.30 1.5 / 2.5 2.50 / 2.25 1 2.5 1.25 / 1 2.25 / 2 2 M5 0.8 2.5 2.58 / 2.520 2.87 2 / 3 3.50 / 3.20 1.25 3.5 1.5 / 1.25 2.75 / 2.5 2.5 M6 1 3 3.08 / 3.020 3.44 2 / 3.5 4.00 / 3.70 1.5 4 1.75 / 1.5 3.25 / 3 3 M8 1.25 4 4.095 / 4.020 4.58 3 / 5 5.50 / 5.20 2 5.5 2.25 / 2 4.3 / 4 5 M10 1.5 5 5.14 / 5.020 5.72 4 / 6 7.00 / 6.64 2.5 7 2.75 / 2.5 5.3 / 5 6 M12 1.75 6 6.14 / 6.020 6.86 4.8 / 8 8.50 / 8.14 3 8.5 3.25 / 3 6.3 / 6 8 M16 2 8 8.175 / 8.025 9.15 6.4 / 10 12.00 / 11.57 4 12 4.3 / 4 8.36 / 8 10 M20 2.5 10 10.175 / 10.025 11.43 8 / 12 15.00 / 14.57 5 15 5.3 / 5 10.36 / 10 14 M24 3 12 12.212 / 12.032 13.72 10 / 15 18.00 / 17.57 6 18 6.3 / 6 12.43 / 12 16 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - fasten.it: DIN EN ISO 4026 socket set screws with flat point, 05-2004: d, P, d1 (dp) max, e min, s nom, t min — web — Publisher's page; dimensions are facts — https://fasten.it/Norms/Norm/DIN_EN_ISO_4026 - fasten.it: DIN EN ISO 4027 socket set screws with cone point, 05-2004: d1 max, s, e, t min range, mass table (commercial lengths) — web — Publisher's page; dimensions are facts — https://www.fasten.it/norms/norm/din_en_iso_4027 - fasten.it: DIN EN ISO 4028 socket set screws with dog point, 05-2004 (replaces DIN 915): d1 max, z max / min (short, long), t min, mass table — web — Publisher's page; dimensions are facts — https://fasten.it/Norms/Norm/DIN_EN_ISO_4028 - fasten.it: DIN EN ISO 4029 socket set screws with cup point, 05-2004: d1 max, s, e, t min range, mass table — web — Publisher's page; dimensions are facts — https://fasten.it/Norms/Norm/DIN_EN_ISO_4029 - Westfield Fasteners: ISO 4026 / DIN 913 dimensions and tolerances table: dp max / min, e min, s nom / max / min, t min (shortest lengths and other lengths), M1.6 to M24 — web — Publisher's page; dimensions are facts — https://westfieldfasteners.co.uk/Standards/ScrewBolt-GrubFlat-M.pdf - AmesWeb: Metric socket set screw dimensions: column headings by point type (dp, dt, dz, z), commercial lengths 2 to 8 mm (tables load dynamically; headings only) — web — Publisher's page; dimensions are facts — https://amesweb.info/Fasteners/Screws/Hex-Socket-Set-Screw-Dimensions-Metric.aspx - MRO Supply: Socket head dog point set screws, metric: 'ISO4028 / DIN915', M4 to M12 lengths 5 to 40 mm — web — Publisher's page; dimensions are facts — https://www.mrosupply.com/fasteners/set-screws/metric/socket-head-dog-point-set-screw No true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.
