Conventions
e Knurl and pilot: Two knurled bands of opposite hand, a groove, a lead and a pilot: their proportions are illustrative, not any maker's design, measured for fit only. Only L, d1 and d2 come from the makers' tables.
e Thread: Simplified: plain bands at d1 and a plain bore at the nominal diameter, so it mates with simplified screws. Threaded: the ISO 68-1 basic internal profile, right hand, the full length, with a 90 degree countersink to the nominal diameter at both ends.
« Values: No published standard: makers' tables. L and d1 count as agreeing only between ruthex and CNC Kitchen; RS PRO counts with ruthex. d2 may stand on ruthex alone, and on CNC Kitchen's three shortest inserts it is ruthex's from the next longer insert with the same thread and d1. Sizes on one maker's table are labelled single source.
« Finish: Polished lead-free brass: render and metadata only. No markings, other edges sharp. Top face, flush with the part's surface, at Z = 0, the pilot end at Z = -L.
« Recommended hole, per maker: CNC Kitchen 4.4 mm, ruthex 4.4 mm.
e Wall around the hole, per maker: CNC Kitchen 1.6 mm, ruthex 1.3 mm.
e Minimum hole depth, per maker: CNC Kitchen 5.0 mm, ruthex 5.0 mm.
e The hole depth is each maker's callout on its drawing added to that maker's L, read twice by Claude, and the two reads agree (ADR 0055).
* CNC Kitchen's values for this size are figure reads: its table is an image, read twice by Claude, and the two reads agree (ADR 0055).
