The newly redesigned line of versatile Dzus Dart quarter-turn fasteners from Southco provides quick-access fastening in high-volume, light-duty applications. Thermoplastic materials allow for a high strength-to-weight ratio and good aesthetic features for applications such as automotive panels, electronics, and other consumer products.
The all-plastic construction delivers corrosion-resistant, non-conducting performance for indoor or outdoor applications and provides a rated life of thousands of cycles. Studs and receptacles designed from complementary materials reduce squeaks, binding, and wear. Dart includes ergonomic headstyles with attractive styling to match end-use applications. Its design allows for custom headstyles with little or no tooling charges. While the standard colour is black, the option to order Dart fasteners in custom colours makes it easier to match the fastener to the application.
Installation is easy, with no special tools required to install the receptacles. Simple push-on retainers captivate the Dart studs. Self-ejecting spring options lift disengaged fasteners above the panel, making it easier to identify hardware in the unfastened position and to remove unfastened panels without damaging fastener hardware.
Four standard head styles – straight slot, slotted knob, an ergonomic wing style, and a hex-recess style – offer a range of convenient-access and restricted-access options to suit specific needs. Five different receptacle styles – front load, rear load, snap-in, clip-on and rivet-plate – each feature built-in stops to resist over rotation, detent features to indicate complete engagement, and built-in spring compliance that provides a degree of vibration resistance.
In order to satisfy a broad scope of fastening opportunities, stud lengths range from 11.4 mm to 25.4 mm and can accommodate total material thicknesses ranging from 2.5 mm to 19.8 mm, depending on the receptacle used. Various receptacle styles accommodate support panel thicknesses ranging from 0.7 mm to 5.5 mm. And with a fit tolerance of 1.2 mm, more forgiving than many other quarter-turn fasteners, Dart Quarter-Turn Fasteners provide greater flexibility for meeting diverse application requirements.
