KCS-WF inserts must be positioned on wood or similar formwork with all nails in contact with the form. The head of the KCS-WF must be impacted with sufficient force to drive nails all the way into the formwork until the plastic base sits flush and tight against the form. From beneath the deck, following the concrete pour and form removal, the three nails may be broken off, and a threaded rod or bolt element must be screwed into the internal threads of the KCS-WF until fully seated in the insert, which will result in a thread engagement equal to one diameter. The threaded steel rod or bolt element must have a minimum thread engagement equal to one steel element diameter. For the KCS-MD inserts, installation parameters are provided in Table 2 and in Figures 4, 6, 7, 8 and 10. A hole must be made in the steel deck using a hole saw in accordance with the corresponding hole diameters shown in Table 2. From the topside of the deck, the KCS-MD plastic sleeve must be placed in the hole, and following this, the head of the insert must be stepped on or impacted with sufficient force to compress the outer spring and drive the flared plastic fins of the sleeve completely through the hole in the steel deck. The KCS-MD metal base plate may be screwed to the deck for additional stability (optional). After insertion in deck, a threaded rod or bolt element must be inserted through the plastic thread protector nozzle until contact is made with the inner steel barrel. The threaded rod or bolt element must then be screwed into the KCS-MD internal threads. The rod or bolt must be tightened until fully seated in the insert, which will result in a thread engagement equal to a minimum of one rod diameter. The plastic sleeve must be cut and trimmed to the surface of the insert following the concrete pour if the insert is intended to resist shear loads. KCS-MD inserts are permitted to be installed in either the upper or lower flute of the steel deck. Installation of KCS-WF and KCS-MD inserts must be in accordance with this evaluation report and the manufacturer s published installation instruction (MPII) as provided in Figures 9 and 10 of this report.
