SS304 401 Stainless Steel Hex Metal Bolts with Nuts Washers Superior Corrosion Resistance

The distinction between fully threaded studs and half-threaded studs: During the design process for stud connections, once the stud diameter and performance grade have been determined, the stud length must also be established. At this stage, one may encounter the dilemma of selecting between fully threaded studs and half-threaded studs. This article outlines the fundamental principles and considerations for selecting between fully threaded studs and half-threaded studs. Where industry or corporate standards explicitly dictate the selection, these principles are superseded, and compliance with the specified standards is required. The terms "fully threaded stud" and "half-threaded stud" refer to studs sharing identical mechanical properties and dimensions but differing in thread length. Generally, no operational distinction arises during use. The selection principles herein primarily address varying application requirements.

Fully threaded studs are typically employed for clamping thinner components or where substantial dynamic or impact loads are present. Certain specialised industries, such as those adhering to ASME standards, also recommend fully threaded studs. Partially threaded studs are generally used for thicker clamping applications. In structural steel stud connections, shear studs commonly utilise partially threaded studs, where the polished rod length must exceed the thickness of one plate side.

When selecting half-threaded studs, both the remaining thread length and thread extension length must be considered. Definitions: Thread extension length primarily accounts for the incomplete thread length u of the stud (typically u < 2P).
