Southco has been in the business for over 70 years. During this time, they have helped the world’s most recognized brands with the design and manufacturing of access solutions and components, including DZUS® Quarter-Turn Fasteners. Their products are innovative and supported by an experienced team. 

Beginning in 1992, HTF secured an authorized distribution partnership with Southco. Since then, our partnership has grown stronger, and it is with great pleasure that we highlight their line of DZUS® Quarter-Turn Fasteners.

What are Quarter-Turn Fasteners?

A quarter-turn fastener is an insert comprised of a stud, retainer, and receptacle, forming a mechanically locking quick-release fastening mechanism. This is the basic function of DZUS® fasteners, ensuring a secure and vibration-resistant fastening while allowing for quick release that can be effortlessly achieved either manually or with a tool.

These fasteners are most often used in panels, where they prove beneficial when a panel needs to be accessed by opening and closing it on a regular basis. If the fit needs to be tight and secure every time, but access should be quick and reliable, then a quarter-turn fastener is a great component. 

Quarter-turn fasteners like DZUS® are often used in automotive, transportation, mechanical, and other equipment applications. Quarter-turn fasteners help technicians access controls, lighting, or electronic components for regular maintenance. The affordability and time savings provide a cost-effective way to gain access via panel for many applications.

How Quarter-Turn Fasteners Work

DZUS® Quarter-Turn Fasteners work by hand or tool operation. They function by activating a cross pin, which can be easily installed using a screwdriver or a compatible tool. As you rotate the head with the tool, the cross pin ascends along the enclosed cam, initiating a loading action. After completing a full 90-degree turn, the cross pin securely settles into the detent.

These fasteners incorporate a spring that imparts force to the crosspin. Typically, the cross pin remains entirely concealed within the body of the quarter-turn fastener. However, turning the head with a tool engages the spring, pushing the cross pin into the detent. Once the cross pin is nestled in the detent, the quarter-turn fastener effectively becomes locked in position.
