UN-5700 Line Fastener Product Selector

The UN-5700 Line stud has a special four-lead thread that operates in less than one turn. The receptacle provides a friction lock by expanding against a surrounding coil spring as the stud is engaged.

Rated locking torque is maintained over thousands of use cycles. These features are combined with the advantages of standard threaded fasteners; panel take-up, no sheet separation under load, and high tensile and shear ratings.

4. Select a receptacle type:

All of the ST-1200 Line receptacles provide the same optimum performance standards as listed in the performance table, so receptacle selection is primarily a matter of choosing the installation mode which provides the lowest installed cost, and perhaps finding a type that will fit in limited space. 

If stainless steel is required, the wire-form springs, weld plates, and press-in types are available.  If an enclosed type is needed, selection is limited to the types available in the SU-2300 Line and the PA-3500 Line.

5. Now determine the Panel, Gap, and Support thickness.

Now determine the thickness of material in which the stud is retained and to which the receptacle is attached.  Then determine the total gap between the level of stud head contact with material and the level of receptacle contact, in the closed position, include any air gaps and any part of the stud retainer thickness not buried in material already measured.  Refer to the examples on each receptacle page, which will guide you to the length selection table.
