Quarter Turn Fasteners Product Line

Quarter Turn Fasteners

A quarter-turn fastener secures a panel with a single quarter turn of a screwdriver or key, instead of multiple full rotations. That speeds up access on panels that get opened and closed often, without giving up a secure hold.

Steeves Agencies carries Southco’s DZUS® quarter-turn fasteners, a long-standing standard in this category, along with compression latch options built on the same quarter-turn principle.

How they work

A quarter-turn fastener consists of a stud, a spring, and a matching receptacle. The stud engages the receptacle and locks into place with a quarter turn, and the spring keeps tension on the joint so it doesn’t work loose from vibration. Because each fastener comes matched to its own receptacle, engagement stays accurate and consistent over repeated use.

Common applications

Quarter-turn fasteners are widely used on equipment panels, enclosures, aerospace and transportation access panels, and anywhere a panel needs frequent, fast, tool-assisted access without the time cost of a fully threaded fastener.

What to consider when choosing a quarter-turn fastener

• Access frequency. These fasteners are built for panels opened and closed often; if a panel is rarely serviced, a standard fastener may be simpler and more economical.
• Compression needs. Some quarter-turn options, like Southco’s E9, also provide compression for sealing against gaskets, combining quick access with an environmental seal.
• Panel thickness and grip range. The stud needs to match the thickness of material it’s securing.
• Vibration resistance. The spring-loaded design helps resist loosening, but confirm the fastener is rated for the vibration levels of your application.
• Tool access. Confirm what’s available to operate the fastener, whether that’s a flathead screwdriver, a key, or a specific driver type.
