320 Zero Diagram


The 320 Zero can be used both to mount to furring and mount to drywall. using field installed or prefabricated furring systems.  The 320 Zero is a hidden fastener that allows fast and easy installation of panels directly into place with Zero reveal.  Examples include ADA panels, soffit panels, panels with no reveal, fabric panels and wood panels that need to be installed straight into the furring.  And also for pre-assembled "L" shaped soffits and corners. The 320 Zero holds individual panels, allowing for 1/16" expansion. 

** 334 Euro Screws are Included with the 320 Zero **


The 320 Zero is a medium duty, one piece, injection molded insert fastener designed to install panels 'straight-in' with zero reveals. The engineered plastic  body and steel screw withstand repeated removal.  The 320 Zero compression fits into a 1.000" drilled hole in any hard substrate. The 320 Zero pushes into a 5/16" mounting screw with about 10 Lbs. of force and can be removed with about 25 Lbs. of force, much like a friction catch.

Note: The 320 Zero has a 10 Lb. weight limit.  It should be used overhead only in combination with a mechanically locked clip.
Mounting Screw Size: Our mounting screw heads are the same size as a standard # 10 panhead screw; other screw types and materials will work.

Cost & Benefit Estimates 

320 Zero can be drilled and installed in under a minute. This is notably faster than traditional clips with a similar cost.
