Benefits of Rolled Threads in Carriage Bolts
Rolled threads on carriage bolts provide superior fatigue resistance and a smoother surface finish, enhancing the reliability of the fastener.
Understanding the application
Thread rolling forms the thread by displacement of material. Its suitability depends on the bolt material and manufacturing sequence.
Selection & technical considerations
Potential surface and fatigue benefits depend on controlled production, not only the process name. Neck and head geometry must also meet the product requirements.
Practical checks before use
Specify the standard and any required process controls. Agree dimensional inspection and material or mechanical test documents.
A complete enquiry includes
