multiNUTS™ - Self-Centering Industrial Fasteners

multiNUTS™ are an innovative, revolutionary Patent Pending design that enables smaller, more cost-effective fasteners to be used in situations where full torque fastening is not required. A great example of one such situation is fastening flange protectors to flanges. Normally, flanged connections require high torque values to ensure a proper leak-free connection.

However, before this connection is made, the flange must be protected. multiNUTS™ allow a flange protector to be installed using full size flange holes with ¼”-20 machine screws. The tapered end of the multiNUTS™ also allow their use in a variety of different hole sizes. This results in savings compared to full-sized nuts and bolts, in addition to simpler logistics since one size fits a variety of different flanges. Our multiNUTS are made of a lightweight, durable plastic that withstands extreme weather and sun exposure.
