Positive Lock Stud

Positive lock studs are fastening devices that are commonly used in various industries for securing components together. They are part of the supply class Fastening Devices in the supply group Hardware and Abrasives.

Positive lock studs are designed to provide a secure and reliable connection between two or more parts. They typically consist of a threaded stud with a locking mechanism that ensures the stud remains securely fastened in place.

The locking mechanism of positive lock studs can vary depending on the specific design. Some common types of locking mechanisms include:

1. Self-locking: These studs have a built-in locking feature that prevents them from loosening or backing out unintentionally. This can be achieved through the use of a locking ring, a nylon insert, or a serrated locking feature on the stud.

2. Thread-locking adhesive: Some positive lock studs are coated with a thread-locking adhesive, such as Loctite, which provides additional resistance to vibration and prevents the stud from loosening.

3. Locking washer: Another common locking mechanism is the use of a locking washer, such as a split washer or a toothed washer. These washers create tension between the stud and the mating surface, preventing the stud from rotating or loosening.

Positive lock studs are available in various sizes, materials, and thread types to accommodate different applications. They are commonly used in industries such as automotive, aerospace, construction, and manufacturing, where secure fastening is crucial for safety and reliability.

When selecting positive lock studs, it is important to consider factors such as the load requirements, environmental conditions, and the specific application. It is also recommended to follow the manufacturer's guidelines for installation and torque specifications to ensure proper and effective use of the positive lock studs.
