The inch rows are the Black Crow guide: drill number, hole range, grip range and rivet length per trade size (41–410, 52–58, 62–616).",
   "The two systems line up: the Olander listing for the 1/8 in AD44 prints a flange diameter of 0.238–0.262 in (6.05–6.65 mm, the Fortress 3.2 mm head range) and a hole of 0.129–0.133 in (3.28–3.38 mm, against 3.3–3.4 mm); the 3/16 in hole 0.192–0.196 in is 4.88–4.98 mm against 4.9–5.0 mm.  Use the rows for your rivet's system.",
   "Head diameter: Fortress prints a range per diameter, not per grip length. For inch rivets only two single-part values were found and they are shown on their own rows: AD44 (1/8 in, grip .188–.250) 0.238–0.262 in and AD52 (5/32 in, grip .063–.125, Stanley Engineered Fastening) 5/16 in. One distributor sheet printed head diameters that grew with grip length (.203 to .765 in for 1/8 in) and conflicted with those two listings, so it was not used.",
   "Inch 'rivet length' is the figure printed in the Black Crow trade-size table; metric 'length' is the Fortress L column.

Sheet values are guide values for aluminium-body rivets with the sheet's own caveat; steel, stainless and closed-end rivets, countersunk heads and large-flange heads have other head dimensions that are not on this page. The Fortress sheet also lists 2.4 and 6.4 mm rivets, not copied here.\n- No file: the body-and-head profile and the mandrel break-point are not published, so a drawing would be invented. McMaster-Carr's pop-rivet pages carry per-part STEP and are linked, not copied.\n\nsystem  rivet diameter  code / trade size  hole / drill  head diameter  grip range  length\nmm  3.2 mm  4-1  3.3 – 3.4  6.05 – 6.65  0.5 – 1.6  5.1\nmm  3.2 mm  4-2  3.3 – 3.4  6.05 – 6.65  1.6 – 3.2  6.7\nmm  3.2 mm  4-3  3.3 – 3.4  6.05 – 6.65  3.2 – 4.8  8.2\nmm  3.2 mm  4-4  3.3 – 3.4  6.05 – 6.65  4.8 – 6.4  9.7\nmm  3.2 mm  4-5  3.3 – 3.4  6.05 – 6.65  6.4 – 7.9  11.4\nmm  3.2 mm  4-6  3.3 – 3.4  6.05 – 6.65  7.9 – 9.5  13.0\nmm  3.2 mm  4-8  3.3 – 3.4  6.05 – 6.65  9.5 – 12.7  16.2\nmm  3.2 mm  4-10  3.3 – 3.4  6.05 – 6.65  12.7 – 15.9  19.4\nmm  3.2 mm  4-12  3.3 – 3.4  6.05 – 6.65  15.9 – 19.1  22.2\nmm  4.0 mm  5-2  4.1 – 4.2  7.52 – 8.33  0.8 – 3.2  7.3\nmm  4.0 mm  5-3  4.1 – 4.2  7.52 – 8.33  3.2 – 4.8  8.9\nmm  4.0 mm  5-4  4.1 – 4.2  7.52 – 8.33  4.8 – 6.4  10.5\nmm  4.0 mm  5-5  4.1 – 4.2  7.52 – 8.33  6.4 – 7.9  12.0\nmm  4.0 mm  5-6  4.1 – 4.2  7.52 – 8.33  7.9 – 9.5  13.6\nmm  4.0 mm  5-8  4.1 – 4.2  7.52 – 8.33  9.5 – 12.7  16.8\nmm  4.0 mm  5-10  4.1 – 4.2  7.52 – 8.33  12.7 – 15.9  20.0\nmm  4.0 mm  5-12  4.1 – 4.2  7.52 – 8.33  15.9 – 19.1  22.5\nmm  4.8 mm  6-2  4.9 – 5.0  9.04 – 10.01  0.8 – 3.2  8.0\nmm  4.8 mm  6-3  4.9 – 5.0  9.04 – 10.01  3.2 – 4.8  9.5\nmm  4.8 mm  6-4  4.9 – 5.0  9.04 – 10.01  4.8 – 6.4  11.1\nmm  4.8 mm  6-5  4.9 – 5.0  9.04 – 10.01  6.4 – 7.9  12.7\nmm  4.8 mm  6-6  4.9 – 5.0  9.04 – 10.01  7.9 – 9.5  14.3\nmm  4.8 mm  6-8  4.9 – 5.0  9.04 – 10.01  9.5 – 12.7  17.5\nmm  4.8 mm  6-10  4.9 – 5.0  9.04 – 10.01  12.7 – 15.9  20.7\nmm  4.8 mm  6-12  4.9 – 5.0  9.04 – 10.01  15.9 – 19.1  23.8\nmm  4.8 mm  6-14  4.9 – 5.0  9.04 – 10.01  19.1 – 22.2  27.0\nmm  4.8 mm  6-16  4.9 – 5.0  9.04 – 10.01  22.2 – 25.4  30.2\nin  1/8 in  41  0.129 – 0.133 (drill #30)  —  .032 – .062  .188\nin  1/8 in  42  0.129 – 0.133 (drill #30)  —  .063 – .125  .250\nin  1/8 in  43  0.129 – 0.133 (drill #30)  —  .126 – .187  .313\nin  1/8 in  44  0.129 – 0.133 (drill #30)  0.238 – 0.262  .188 – .250  .375\nin  1/8 in  45  0.129 – 0.133 (drill #30)  —  .251 – .312  .438\nin  1/8 in  46  0.129 – 0.133 (drill #30)  —  .313 – .375  .500\nin  1/8 in  48  0.129 – 0.133 (drill #30)  —  .376 – .500  .625\nin  1/8 in  410  0.129 – 0.133 (drill #30)  —  .501 – .625  .750\nin  5/32 in  52  0.160 – 0.164 (drill #20)  5/16 (0.312)  .063 – .125  .275\nin  5/32 in  53  0.160 – 0.164 (drill #20)  —  .126 – .187  .338\nin  5/32 in  54  0.160 – 0.164 (drill #20)  —  .188 – .250  .400\nin  5/32 in  56  0.160 – 0.164 (drill #20)  —  .251 – .375  .525\nin  5/32 in  58  0.160 – 0.164 (drill #20)  —  .376 – .500  .650\nin  3/16 in  62  0.192 – 0.196 (drill #11)  —  .063 – .125  .300\nin  3/16 in  64  0.192 – 0.196 (drill #11)  —  .126 – .250  .425\nin  3/16 in  66  0.192 – 0.196 (drill #11)  —  .251 – .375  .550\nin  3/16 in  68  0.192 – 0.196 (drill #11)  —  .376 – .500  .675\nin  3/16 in  610  0.192 – 0.196 (drill #11)  —  .501 – .625  .800\nin  3/16 in  612  0.192 – 0.196 (drill #11)  —  .626 – .750  .925\nin  3/16 in  614  0.192 – 0.196 (drill #11)  —  .751 – .875  1.050\nin  3/16 in  616  0.192 – 0.196 (drill #11)  —  .876 – 1.000  1.175\n\nFiles elsewhere (not hosted by Xem Studio; license as stated by the publisher):\n- Fortress (Steel & Tube NZ): Blind rivet domed and CSK head, all aluminium: spec sheet (rivet diameter, hole size, head diameter, grip range, length) — web — Maker spec sheet (guide values); numbers only — https://marketing.steelandtube.co.nz/hubfs/Website%20Catalogues/Fasteners/Fortress%20Blind%20Rivet%20DOMED%20&%20CSK%20HEAD%20-%20ALL%20ALUM%20Spec%20Sheet%20Oct%202024_web.pdf\n- Black Crow Fasteners: Blind rivet reference guide: drill number and hole size, trade size, rivet length and grip range for 1/8, 5/32, 3/16 in — web — Publisher's page; dimensions are facts — https://www.blackcrowfasteners.com/cs_wiki/wiki/50-blind-rivet-reference-guide\n- Olander (distributor): AD44ABS pop rivet 1/8 in dome head: hole 0.129–0.133 in, drill #30, flange diameter 0.238–0.262 in, grip 0.188–0.250 in — web — Publisher's page; dimensions are facts — https://www.olander.com/items/AD44ABS\n- Zoro (distributor): Stanley Engineered Fastening AD52ABS201 blind rivet, 5/32 in dome head: head 5/16 in, grip 0.063–0.125 in, drill #20 — web — Publisher's page; dimensions are facts — https://www.zoro.com/pop-avdel-blind-rivet-domed-head-532-in-dia-0275-in-l-aluminum-body-500-pk-ad52abs201/i/G2207362\n- McMaster-Carr: Pop (blind) rivets (free STEP/IGES per part, for your own design use; no redistribution) — STEP, IGES, PDF — McMaster-Carr site terms: personal design use, no redistribution [verify license at link] — https://www.mcmaster.com/products/pop-rivets/\n\nNo true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.\nAPI: https://xemstudio.com/api/geometry?object=blind-pop-rivets-dome-head\n",
