All Nut Types on One Page

Nut geometry, material pairing, thread class and proof requirements are reviewed against the mating fastener and assembly conditions.

Standard: ASME B18.2.2, DIN 934, ISO 4032 or drawing
Configuration: Finished hex nut
Materials: Inconel 625, Inconel 718, Hastelloy C-276, Alloy 20 and specified nickel-based alloys
Testing: Dimensional inspection; PMI, hardness, tensile or additional testing when specified

Standard-width nut

Hex Nuts

Hexagonal nuts for general industrial bolting in corrosion and heat-critical systems.

Standard: ASME B18.2.2, ASTM project requirements or drawing
Configuration: Heavy hex, chamfered faces
Materials: Inconel 625, Inconel 718, Hastelloy C-276, Alloy 20 and specified nickel-based alloys
Testing: Dimensional inspection; PMI, hardness, tensile or additional testing when specified

High-bearing-area nut

Heavy-pattern nuts for pressure joints and large-diameter alloy bolting systems.

Standard: ASME B18.2.2 or drawing
Configuration: Thin hex pattern
Materials: Inconel 625, Inconel 718, Hastelloy C-276, Alloy 20 and specified nickel-based alloys
Testing: Dimensional inspection; PMI, hardness, tensile or additional testing when specified

Reduced-height lock nut

Low-profile nuts used for locking, adjustment and constrained assembly envelopes.

Standard: Customer drawing and agreed specification
Configuration: Special external form or locking feature
Materials: Inconel 625, Inconel 718, Hastelloy C-276, Alloy 20 and specified nickel-based alloys
Testing: Dimensional inspection; PMI, hardness, tensile or additional testing when specified

Drawing-based nut

Slotted, round, prevailing-torque and machined nut forms developed around the assembly.
