Jam Nut Sockets

The correct application of torque is essential to most connector applications where Jam Nut receptacle connectors are used. The sealing components (usually an "O" ring) must be compressed, but not to the point of damage. Another consideration when tightening Jam Nuts is the thread strength. This is extremely important in the various types of aluminum and composite connectors.

JAM NUT SOCKETS

DMC Jam Nut Socket tools have been developed specially for the installation of Jam Nut receptacle connectors. They are available in a versatile composite construction which is an excellent choice for OEM assembly areas due to their light weight, and the non marking surfaces, a durable machined aluminum series and the traditional "General Purpose" formed steel socket for non-torque specific applications.

COMPOSITE JAM NUT SOCKETS

A unique process was developed to mold this composite material which contains a higher percentage of fiber glass than is customarily used in conventional molding technology. this makes them as light and a s strong as possible.

The material will not scratch plating, or damage the finish on cabinets, panels or bulkheads when properly used.

ALUMINUM JAM NUT SOCKETS

When a metal socket is required, the anodized aluminum series jam nut sockets are a good choice. They are machined to the same configuration as the composite jam nut sockets with the square hold drive for torquing.

STEEL JAM NUT SOCKETS

Also available are formed Steel Jam Nut sockets. These are plated for corrosion resistance, and have drive holes to accommodate a metal rod, or similar, drive tool.

We also recommend that you consider DMC Safe-T-Cable™ to secure Jam Nut receptacles where lock wire holes are provided.
