Description

945 Rivnut is a reliable and well tested fastener, from the metal working industry. The 945 Rivnut was the original blind installed internally threaded rivet and was invented in 1936 for the purpose of attaching a rubber aircraft-wing de-icer to the leading edge of the wings. (Patent #2,149,199)

Star Hanger Systems sells the 945 Rivnut for use with the 237 Mounting Bolt 3/16" & 337 Mounting Bolt 5/16" however they are widely available from many other sources.

Cost Benefit Estimates

The cost of the Mounting Bolt System, varies with the combination used. With this system, the hardware cost for direct connection to steel panels, is about $0.43 per square foot.

Common applications will be for pre-sized panels with the 210 Lock plant-installed and sent out to the field, with a template or 211 Alignment Pins 3/16", for installing the 945 Rivnut and 237 Mounting Bolt 3/16" onsite:

Required:
210 Lock                         $ 0.59 
237 Mounting Bolt 3/16"  $ 0.29
945 Rivnut                       $ 0.29
Total:                               $ 1.17  Per Connection 

12 fasteners per 4 ft. x 8 ft. panel = $ 20.04 per panel or $ 0.43 per sq.ft.

Product Advantages

Tensile Failure (Horizontal pull) = 200 lbs.
Working Strength, Pull from Furring = 30 lbs.
Shear Failure (Vertical weight holding) = 150  lbs. (bends noticeably)
SWL. Safe Working Load = 25 lbs.
