Blind (pop) rivets, dome head: 3.2, 4.0, 4.8 mm and 1/8, 5/32, 3/16 in: hole size, head diameter, grip range, length — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/blind-pop-rivets-dome-head/ (sheet CC BY 4.0) Basis: Fortress all-aluminium blind rivet spec sheet (metric), Black Crow Fasteners reference guide (inch hole / grip / length), Olander and Zoro listings for two head diameters. Numbers only: the shape is a dome head, a short body and a break-stem mandrel, with no published profile Catalog version: 2026-10-20 Sizes: see table below - The metric rows are the Fortress spec sheet: rivet diameter 3.2, 4.0, 4.8 mm, hole size range, a head-diameter range per diameter, grip range and length per rivet code (the sheet calls the diameters 'D' and the codes 4-x, 5-x, 6-x). 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. - 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. system rivet diameter code / trade size hole / drill head diameter grip range length mm 3.2 mm 4-1 3.3 – 3.4 6.05 – 6.65 0.5 – 1.6 5.1 mm 3.2 mm 4-2 3.3 – 3.4 6.05 – 6.65 1.6 – 3.2 6.7 mm 3.2 mm 4-3 3.3 – 3.4 6.05 – 6.65 3.2 – 4.8 8.2 mm 3.2 mm 4-4 3.3 – 3.4 6.05 – 6.65 4.8 – 6.4 9.7 mm 3.2 mm 4-5 3.3 – 3.4 6.05 – 6.65 6.4 – 7.9 11.4 mm 3.2 mm 4-6 3.3 – 3.4 6.05 – 6.65 7.9 – 9.5 13.0 mm 3.2 mm 4-8 3.3 – 3.4 6.05 – 6.65 9.5 – 12.7 16.2 mm 3.2 mm 4-10 3.3 – 3.4 6.05 – 6.65 12.7 – 15.9 19.4 mm 3.2 mm 4-12 3.3 – 3.4 6.05 – 6.65 15.9 – 19.1 22.2 mm 4.0 mm 5-2 4.1 – 4.2 7.52 – 8.33 0.8 – 3.2 7.3 mm 4.0 mm 5-3 4.1 – 4.2 7.52 – 8.33 3.2 – 4.8 8.9 mm 4.0 mm 5-4 4.1 – 4.2 7.52 – 8.33 4.8 – 6.4 10.5 mm 4.0 mm 5-5 4.1 – 4.2 7.52 – 8.33 6.4 – 7.9 12.0 mm 4.0 mm 5-6 4.1 – 4.2 7.52 – 8.33 7.9 – 9.5 13.6 mm 4.0 mm 5-8 4.1 – 4.2 7.52 – 8.33 9.5 – 12.7 16.8 mm 4.0 mm 5-10 4.1 – 4.2 7.52 – 8.33 12.7 – 15.9 20.0 mm 4.0 mm 5-12 4.1 – 4.2 7.52 – 8.33 15.9 – 19.1 22.5 mm 4.8 mm 6-2 4.9 – 5.0 9.04 – 10.01 0.8 – 3.2 8.0 mm 4.8 mm 6-3 4.9 – 5.0 9.04 – 10.01 3.2 – 4.8 9.5 mm 4.8 mm 6-4 4.9 – 5.0 9.04 – 10.01 4.8 – 6.4 11.1 mm 4.8 mm 6-5 4.9 – 5.0 9.04 – 10.01 6.4 – 7.9 12.7 mm 4.8 mm 6-6 4.9 – 5.0 9.04 – 10.01 7.9 – 9.5 14.3 mm 4.8 mm 6-8 4.9 – 5.0 9.04 – 10.01 9.5 – 12.7 17.5 mm 4.8 mm 6-10 4.9 – 5.0 9.04 – 10.01 12.7 – 15.9 20.7 mm 4.8 mm 6-12 4.9 – 5.0 9.04 – 10.01 15.9 – 19.1 23.8 mm 4.8 mm 6-14 4.9 – 5.0 9.04 – 10.01 19.1 – 22.2 27.0 mm 4.8 mm 6-16 4.9 – 5.0 9.04 – 10.01 22.2 – 25.4 30.2 in 1/8 in 41 0.129 – 0.133 (drill #30) — .032 – .062 .188 in 1/8 in 42 0.129 – 0.133 (drill #30) — .063 – .125 .250 in 1/8 in 43 0.129 – 0.133 (drill #30) — .126 – .187 .313 in 1/8 in 44 0.129 – 0.133 (drill #30) 0.238 – 0.262 .188 – .250 .375 in 1/8 in 45 0.129 – 0.133 (drill #30) — .251 – .312 .438 in 1/8 in 46 0.129 – 0.133 (drill #30) — .313 – .375 .500 in 1/8 in 48 0.129 – 0.133 (drill #30) — .376 – .500 .625 in 1/8 in 410 0.129 – 0.133 (drill #30) — .501 – .625 .750 in 5/32 in 52 0.160 – 0.164 (drill #20) 5/16 (0.312) .063 – .125 .275 in 5/32 in 53 0.160 – 0.164 (drill #20) — .126 – .187 .338 in 5/32 in 54 0.160 – 0.164 (drill #20) — .188 – .250 .400 in 5/32 in 56 0.160 – 0.164 (drill #20) — .251 – .375 .525 in 5/32 in 58 0.160 – 0.164 (drill #20) — .376 – .500 .650 in 3/16 in 62 0.192 – 0.196 (drill #11) — .063 – .125 .300 in 3/16 in 64 0.192 – 0.196 (drill #11) — .126 – .250 .425 in 3/16 in 66 0.192 – 0.196 (drill #11) — .251 – .375 .550 in 3/16 in 68 0.192 – 0.196 (drill #11) — .376 – .500 .675 in 3/16 in 610 0.192 – 0.196 (drill #11) — .501 – .625 .800 in 3/16 in 612 0.192 – 0.196 (drill #11) — .626 – .750 .925 in 3/16 in 614 0.192 – 0.196 (drill #11) — .751 – .875 1.050 in 3/16 in 616 0.192 – 0.196 (drill #11) — .876 – 1.000 1.175 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - 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 - 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 - 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 - 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 - 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/ No true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.
