The 11-3871 features a standard M5 metric thread with a 16mm length, a common size found in various Tweco assemblies. The defining feature of this nut is its integrated flange. This wide base acts like a built-in washer, distributing the pressure of the nut over a larger surface area. This is particularly important in welding environments where equipment is subject to constant vibration and thermal expansion. The flange helps prevent the nut from loosening over time and protects the underlying surface from damage during tightening.
