The RAM-MARI-RIVET-4U consists of (4 qty) aluminum 1/8" pop rivets for blind hole mounting applications.

Grip Thickness:
1/16" to 1/4" 

Installation Instructions:
1. Locate RAM base to desired mounting location, drill holes with 7/32" drill. 
2. Place Mari-Rivet™ body all the way through RAM base and pre-drilled 7/32" holes until flange is firmly secured against mounting surface. 
3. Insert rivet gun over mandrel head. 
4. Clamp rivet gun; this will initiate the jaws to retract, extracting the mandrel, which pulls the mandrel head into the rivet body setting the rivet. At a predetermined tensile load, the mandrel breaks from its head and is discarded.

The "U" in the part number reflects product packaged in poly bag.
