Arconic Fastening Systems and Rings offers a wide variety of captive screws. These fasteners have been integral components in thousands of products made by virtually every major airframe and electronics manufacturer worldwide. Whether specified for use in aerospace, electronics, transportation or industrial products, these trusted captive screws have served industry for more than 50 years. Arconic Fastening Systems and Rings' captive screws are engineered for strength, reliability and performance.
The advantages of using captive screws include the prevention of loss, reduced inventory and improved speed of assembly and disassembly. They also enhance product safety by reducing the potential for loose hardware in moving parts. Turn-Loc® captive screws
are spring loaded and available as fully or partially retracting versions in fixed or floating installations. The attractive stainless or anodized aluminum finish makes them especially suitable for front panel applications and the knurled knob permits easy fingertip operation. Turn-Loc® fasteners are available in low and high profile assemblies.
Our crimp ring captive screw
design allows for a mechanically installed ring to permanently attach the screw to the panel. The attachment is by means of a simple hand tool.
Low profile captive screw assemblies are the answer when parent material thickness is not sufficient to countersink, but protrusion must be kept to a minimum. The controlled thread length of the stud provides adequate thread for engagement with the mating part while allowing maximum play along the axis of the sleeve preventing jacking.
Medium profile captive screw assemblies are designed with a sleeve/standoff that allows finger gripping of the screw for easy engagement and has torquing features for use with a standard driver. This design allows threaded disengagement from the mating part without causing jacking.
High profile all-stainless captive screw assemblies are spring loaded to provide holdout following disengagement. The assembly is captivated to the panel by a nut retainer that is mated with internal threads in the sleeve, providing improved resistance to shear loads.
Jacking screws are a high-strength captive screw designed for the dual purpose of panel retention combined with jacking action for panel removal. The steel sleeve that captivates the screw to the panel is partially swaged over the screw head to provide a smooth, controlled jacking force when the fastener is removed.
