   "Nord-Lock washers are used as a pair: two washers with cam faces on one side and radial teeth on the other, so any thread movement has to ride up the cam and clamp harder. The tables give one Øi (inside), one Øo (outside) and one T per pair name (NL6 for M6, NL1/2\" for 1/2 in). 'sp' is the enlarged-outer-diameter version at the same inside diameter (the maker: sp washers 'have the same inner diameter as the standard washers'). Standard sizes M3 to M42 and #5 to 1-1/2 in; sp sizes M3.5 to M36 and #6 to 1-3/8 in; NL45 to NL130 have no sp version in the tables.",
   "Where the two tables disagree (listed, and flagged per row): NL1/4 (T 1.8); NL30sp (Øo 58.5, T 6.6); NL33sp (T 6.6); NL36 (T 6.6); NL39 (T 6.6); NL42 (T 6.6). Nord-Lock's own pages match the Irontrade table wherever they were read (NL3 3.4 / 7 / 1.8, NL1\" 27.9 / 39 / 3.4, NL1/2\"sp 13.5 / 25.4 / 3.4). Neither source says whether T is the thickness of the pair or of one washer. The files and rows use the Irontrade numbers, and only the 18 sizes where both tables agree are drawn.",
   "Material (Nord-Lock NL3 page): steel EN 1.7182, hardness 465 HV1 or more, zinc flake coating (Delta Protekt), temperature -50 to 200 °C. Tolerances (Irontrade): Øi ±0.1 to ±0.5 mm depending on size, Øo ±0.2 to +0 / -2.0 mm, T ±0.25 mm (NL3 to NL42) and ±0.75 mm (NL45 to NL130). Stainless and other grades are separate Nord-Lock products not tabled here.",
