Locating bolts also called bolts or stepped bolts, are non-standard precision hardware components that integrate "locating" and "fastening" functions.
The core advantage of the positioning bolt lies in its integration of the positioning shoulder, hexagonal flange, and external thread section into a single unit, achieving a dual function of "positioning + locking." The left external thread section can mate with a nut or internal threaded hole, providing reliable axial fastening force; the cylindrical shoulder on the right serves as a precise positioning datum, achieving a clearance-free fit with the mating hole through tolerance control, ensuring installation coaxiality and positional accuracy.
Leveraging its precise positioning capabilities, the positioning bolt plays a crucial role in multiple industries. In industrial automation, it is a core positioning component of tooling fixtures, ensuring the consistency of workpiece position during repeated clamping and reducing machining errors. In automotive manufacturing, it is commonly used for positioning connections in body parts and transmission mechanisms, ensuring assembly accuracy and structural stability.
As a non-standard customized part, the positioning bolt's machining relies on a high-precision CNC lathe to complete the entire turning process. From bar stock blanking, thread turning, flange forming to shoulder precision machining, every step is strictly executed according to drawing tolerances. The coaxiality and cylindricity of key positioning surfaces are controlled within 0.01mm, ensuring a perfect fit with mating parts. Some high-requirement products also undergo surface polishing and deburring; the threaded sections use standard metric/tooth profiles to ensure interchangeability with general fasteners, balancing customization and versatility.
Since there is no unified national standard for positioning bolts, selection must be based on the core requirements of the actual working conditions: First, determine the thread specification, shoulder diameter, and length to match the dimensions of the mating parts; second, select the material and surface treatment according to the usage environment, such as prioritizing anodized aluminum alloy for outdoor equipment and stainless steel for heavy-duty scenarios; finally, based on the positioning accuracy requirements, clarify the tolerance level of key dimensions, and if necessary, customize structures with internal holes, special tooth profiles, or non-standard flanges. Professional CNC machining manufacturers can quickly produce samples and mass-produce according to customer drawings, providing precise solutions for various non-standard assembly scenarios.
