Sioux Chief Sammy® Mechanical Anchors shall be used for suspended applications
where 3/8" threaded rod is used on wood, steel or concrete, in either vertical or
horizontal applications. Sioux Chief Sammy XPress® anchors are specifically
designed for use in metal deck or Z-purlin applications. Swivel models are designed
for extreme or variant roof pitches.
These products should only be installed using original Sammy® nut drivers and
XPress® Nut drivers. Using any other tool voids warranty. When the appropriate nut
driver is used, the driver spins free on the screw after installation is complete and
eliminates the expected wrist snap, reduces over-torque and prevents screw failure.
Complete installation instructions are provided in each box of product. Contact
factory for more information. Due to variations of hardness of certain metals, it
should be noted that self-drilling screws for steel will experience different drill
speeds. Drill speeds of 500 - 1500 RPM should be used.
