WebThe design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Each thread is characterized by its major diameter and its pitch. ISO metric threads consist of symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. Web31 okt. 2024 · View in your space. Use the image and chart below to determine what dimensions to use, all dimensions are in millimetres. For example, a JIS M4 socket cap head bolt with a normal fit counterbored hole will require a pilot hole diameter of 4.5 mm, a counterbore diameter of 8 mm, and a counterbore depth of 4.8 mm.

WebTap tolerance vs. tolerance on internal thread (nut) Normal tap tolerance is ISO 2 (6H), which generates an average quality fit between screw and nut. Lower tolerance (ISO 1) generates a fine fit without a gap on the flanks between screw and nut. Higher tolerance (ISO 3) generates a rough fit with a large gap. This is used if the nut is coated ... • ISO 68-1: ISO general purpose screw threads — Basic profile — Metric screw threads. • ISO 261: ISO general purpose metric screw threads — General plan. • ISO 262: ISO general purpose metric screw threads — Selected sizes for screws, bolts and nuts.
