About this deal

The ISO metric screw thread is the most commonly used type of general-purpose screw thread worldwide. [1] They were one of the first international standards agreed when the International Organization for Standardization (ISO) was set up in 1947.

Use in the repair and the reconstruction of the craniofacial skeleton due to trauma, especially for the osteosynthesis of ISO 262:1998 ISO general purpose metric screw threads – Selected sizes for screws, bolts and nuts. International Organization for Standardization. 17 December 1998. In an external (male) thread (e.g. on a bolt), the major diameter D maj and the minor diameter D min define maximum dimensions of the thread. This means that the external thread must end flat at D maj, but can be rounded out below the minor diameter D min. Conversely, in an internal (female) thread (e.g. in a nut), the major and minor diameters are minimum dimensions; therefore the thread profile must end flat at D min but may be rounded out beyond D maj. In practice this means that one can measure the diameter over the threads of a bolt to find the nominal diameter D maj, and the inner diameter of a nut is D min.

ISO 965-5: Limits of sizes for internal screw threads to mate with hot-dip galvanized external screw threads with maximum size of tolerance position h before galvanizing The L1® Midface system is used in particular for the treatment of fractures, fixation of osteotomies, and within the context of reconstructive procedures in the midface area. The coarse pitch is the commonly used default pitch for a given diameter. In addition, one or two smaller fine pitches are defined, for use in applications where the height of the normal coarse pitch would be unsuitable (e.g. threads in thin-walled pipes). The terms coarse and fine have (in this context) no relation to the manufacturing quality of the thread. The minor diameter D min and effective pitch diameter D p are derived from the major diameter and pitch as The "M" designation for metric screws indicates the nominal outer diameter of the screw thread, in millimetres. This is also referred to as the "major" diameter in the information below. It indicates the diameter of smooth-walled hole that a male thread (e.g. on a bolt) will pass through easily to connect to an internally threaded component (e.g. a nut) on the other side. That is, an M6 screw has a nominal outer diameter of 6 millimetres and will therefore be a well-located, co-axial fit in a hole drilled to 6mm diameter.

International Organization for Standardization. 15 September 2013. Below are some common spanner (wrench) sizes for metric screw threads. Hexagonal (generally abbreviated to "hex") head widths (width across flats, spanner size) are for DIN 934 hex nuts and hex head bolts. Other (usually smaller) sizes may occur to reduce weight or cost, including the small series flange bolts defined in ISO 4162 which typically have hexagonal head sizes corresponding to the smaller 1st choice thread size (eg. M6 small series flange bolts have 8mm hexagonal heads, as would normally be found on M5 bolts). [9]ISO 68-1:1998 ISO general purpose screw threads – Basic profile – Part 1: Metric screw threads.
