Technical Threads stocks and supplies Monel 400 (as well as a limited amount of Monel K-500) fasteners, including studs, hex cap screws, finished and heavy hex nuts, socket head cap screws, flat washers and lock washers. Mil-spec and domestic materially is also often readily available.

Additional, Monel 400 u-bolts are commonly supplied to both standard and custom dimensions.

Monel is commonly used on flanged piping systems, which are commonly found in the chemical industry, as well as environments exposed to salt-water. Additionally, it’s one of the most commonly supplied alloys when 316SS does not provide enough general corrosion resistance. As a result, it’s one of the most available for high alloys, which has resulted in increasing use in a variety of industrial applications beyond pipe flanges including:

    Valve bonnet bolting
    Pump housing bolting
    Cylinder flange bolting
    Pressure tank bolting
    Manhole cover bolting

Common Specs include:
