The standard six-sided nut for general assembly with bolts, studs and threaded rods.

Four-sided nuts with a large bearing area and firm wrench grip, used in rugged and traditional fastening.

Thin hex nuts used as a locking nut against a standard nut to resist loosening.

Thicker, wider nuts for high-load structural, flange and pressure-service joints.

Low-profile square nuts for tight spaces and light-duty locking.

Nylon insert lock nuts that resist vibration loosening.

Domed, closed-end nuts that cover the bolt end for protection and a neat finish.

Square nuts with weld projections for fixing onto sheet metal and steel parts.

Thin nylon insert lock nuts for low-clearance, vibration-prone assemblies.

Integral flange spreads load and removes the need for a separate washer.

Long internally threaded nuts that join two threaded rods or studs.

Decorative domed nuts that cover exposed threads and protect against injury and corrosion.

Hex nuts with weld projections for permanent attachment to metal components.

Nuts with a forged eye for lifting, rigging and attachment points.

Nuts with two wings for quick tightening and removal by hand.

Nuts shaped to slide into T-slots in machine tables, jigs and aluminium profiles.

Hex nuts with an attached free-spinning external tooth lock washer.

Reusable all-metal lock nuts that grip the thread under vibration.

Prevailing torque nuts without nylon, suited to higher temperatures.

Slotted nuts that accept a split pin to prevent loosening in critical assemblies.

Twelve-point flanged nuts for compact, high-torque engine and machinery use.

Wheel nuts that secure vehicle wheels to hubs, with tapered or flat seats.

Open-ended lug nuts that allow the stud end to show through for easy checking.
Choose the right material for strength, corrosion resistance and temperature. Each material has its own page with grades and specifications.
