Threads on parallel fasteners use a cylindrical blank having an outside diameter between the major and minor diameters of the finished thread A bar is rotated between hardened steel dies bearing the reverse thread form The die threads penetrate the blank surface to form the thread roots and displace material radially outward to form the crests
Portland Bolt produces bent bolts with cut threads from 1 2 quot diameter through 4 1 2 quot diameter and reduced body rolled thread bent bolts from 3 8 quot diameter through 1 quot diameter Nuts Our inventory of nuts include both domestic and import and are compatible for many grades of bolts in either plain or hot dip galvanized finish
This relationship is based on the assumption that regular series nuts and bolts with rolled threads are used acting on surfaces with industry standard thread pitch and flank angle References John H Bickford An Introduction To The Design and Behavior of Bolted Joints Marcel Dekker Inc New York 1990
All standard bolt sizes and thread types can be manufactured via cutting Generally bolts and screws with cut threads have better shear strength but are also more complicated to manufacture and more expensive To fabricate rolled threads a blank with a diameter slightly smaller than the designated end diameter is used
03 05 2014 nbsp 0183 32 Rolled Thread Bolts Have Smaller Bodies Find the hardware solutions you re looking for here With the cut threading process manufacturers can obtain a bolt with a full one diameter body and one diameter threading whereas the rolled threading reduces the fastener s body to only 912 inches while maintaining the threading to one inch diameter

Roll threading is a very efficient method of manufacturing threads on bolts and other fasteners Learn the benefits and limitations of this popular technique
In fact the thread root is so shallow that the bolt thread cannot mate with a UN nut so there is a UNJ nut specification as well Thread Production Thread Production Rolled threads are formed by rolling the reduced diameter approximately equal to the pitch diameter portion of the shank between two reciprocating serrated dies
