Apr 01, 2001 · This part of ISO 4759 specifies a selection of tolerances for bolts, screws. studs and nuts with ISO metric threads and with product grades A, B and C and for tapping screws with product grade A. NOTE The product grades refer to the size of the tolerances where grade A is the most precise and grade C is the least precise. Fabory Fasteners - Engineers Merchant & Industrial 5. Screw thread tolerances The basis for the layer thickness of electroplated coatings is given by the tolerances for ISO-metric screw threads in accordance with DIN 13 resp. ISO-unified screw threads in accordance with ISO 5864 (ANSI B1.1) prior to the electroplating, that means tolerance field g resp. 2A for bolts and screws and H resp. 2B
equivalent to ISO class fit 4H5H/4h6h. Default metric fastener thread pitch. If metric thread pitch designation (e.g., " x 1.5") is omitted, it specifies coarse pitch threads. For example, M10 or M10-6g, by default, specifies M10 x 1.5.
