Comparable in strength to Grade 9 bolts, these coupling nuts are about 20% stronger than high-strength steel coupling nuts. Available in inch thread sizes.

18-8 Stainless Steel Coupling Nuts

These coupling nuts have good chemical resistance.

Metric 18-8 Stainless Steel Coupling Nuts

These metric coupling nuts have good chemical resistance.

Super-Corrosion-Resistant 316
Stainless Steel Coupling Nuts

More corrosion resistant than 18-8 stainless steel coupling nuts, these nuts have excellent resistance to chemicals and salt water.

Metric Super-Corrosion-Resistant
316 Stainless Steel Coupling Nuts

More corrosion resistant than 18-8 stainless steel coupling nuts, these metric nuts have excellent resistance to chemicals and salt water.

Brass Coupling Nuts

Brass coupling nuts are corrosion resistant in wet environments and electrically conductive.

Aluminum Coupling Nuts

One-third the weight of steel, aluminum coupling nuts resist corrosion in wet environments.

Plastic Coupling Nuts

Plastic coupling nuts are chemical resistant, nonconductive, and lightweight.

Extra-Long Coupling Nuts

Stainless Steel Extra-Long Coupling Nuts

Stainless steel coupling nuts have excellent corrosion resistance in most environments.

Steel Extra-Long Coupling Nuts

Known for their strength, steel coupling nuts are available with a corrosion-resistant finish.

Coupling Nuts with Sight Hole

Use the sight hole to check for proper thread engagement.

Female Thread Adapters

Inch-to-Inch Female Hex Thread Adapters

Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench.

Inch-to-Metric Female Hex Thread Adapters

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

Left-Hand to Right-Hand Female Hex Thread Adapters

Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.

Metric-to-Metric Female Hex Thread Adapters

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

Power Transmission

Acme Lead Screws and Nuts

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects.

Metric Acme Lead Screws and Nuts

These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.

Turnbuckle-Style Connecting Rods

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension. Add right- and left-hand threaded rod ends to build your linkages.

Internally Threaded Turnbuckle-Style Connecting Rods

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension.

Quick-Clamping Coil-Threaded Rods, Screws, and Nuts

Combine fast-threading components to build a clamping assembly.
