Overview The Unified Thread Standard (UTS) defines a 60° thread form in Inch dimensions as described in the ASME B1.1 standard. It is the North American HexSocket Head Cap Screws UNF from SUNCO.

Threadgeometry - Unified Fine (UNF) All dimensions in mm unless otherwise stated. d1 - Minor thread diameter male. d2 - Minor thread diameter female. d3 - Pitch diameter. d4 - Major diameter. Thread. 29 Acme thread = 8:1 7°/ 45° Buttress thread = 4.3138:1 10° Square thread = 23:1 Based on the ratios above you can see how much affect a specific amount of plating can build up on a thread. There are several screw thread engineering programs that will handle the calculations for pre plating , including ThreadTech v2.24. TheNominal Major Diameter and Threads-per-inch (Pitch) are defined by ANSI/ASME B1.1 and are the choices for the customary Unified screws and nuts. This data is provided for general information only. The intention is to provide accurate information; regardless; errors may exist in the supplied information. If accuracy is critical, base your . Thisstatement in B1.1 means that the threads described on a drawing as “Class 2A” are to be inspected using the size limits for Class 2A BEFORE PLATING OR COATING. This means that the Class 2A GO and 2A NOGO limits and gages must be used to inspect and accept the pre-plated or coated threads. After the threaded parts are Onceyou know your wire diameter, you need to find out what is the premissable Measurement for your pitch diameter (Depending on the class).
