Hex Jam Nuts On National Bolt & Nut Corp.

As part of our premium line of hex nut products, National Bolt & Nut offers a series of hex jam nuts that meet ANSI B18.2.2 dimensional specifications. Thinner than a conventional hex nut, our hex jam nuts can be constructed using a variety of materials. A number of finish options are also available upon request.
Hex jam nuts can be employed for leveling purposes or to lock a standard nut in place when threaded into a bolt and run tight against that nut. With our premium hex jam nuts, nylon inserts and nuts with patches are also available options and can be solicited through our information request form.
Other materials and finishes available. For further information, call or send an information request.
