Fastening Tools

The opening is designed to grip threaded rod for quick installation and removal without damaging the threads.

Threaded Rod and Stud Driver Bits

Quickly install threaded rods and studs using a cordless drill, instead of doing it by hand.

Coupling Nuts

High-Strength Steel Coupling Nuts—Grade 8

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.

Metric High-Strength Steel Coupling Nuts—Class 10

These metric-sized coupling nuts are Class 10 steel, so they’re about 25% stronger than medium-strength steel coupling nuts.

Metric Low-Strength Steel Coupling Nuts

For light duty applications, choose these metric-sized coupling nuts.

Low-Strength Steel Coupling Nuts

About half the strength of medium-strength steel coupling nuts, these nuts are for light duty fastening applications.

Left-Hand Threaded Low-Strength Steel Coupling Nuts

The left-hand threads on these coupling nuts resists loosening from counterclockwise vibration. Use in light duty applications.

Extreme-Strength Steel Coupling Nuts

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.

Medium-Strength Steel Coupling Nuts—Grade 5

Made from Grade 5 steel, these inch-sized coupling nuts are suitable for most applications.

Metric Medium-Strength Steel Coupling Nuts—Class 8

Choose these locknuts to fasten standard metric threads. They’re Class 8 steel, so they can be used in most fastening applications.

Brass Coupling Nuts

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

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.

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.

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.

Plastic Coupling Nuts

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

Aluminum Coupling Nuts

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

Steel Extra-Long Coupling Nuts

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

Stainless Steel Extra-Long Coupling Nuts

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

Round Coupling Nuts

A smooth rounded body provides a finished look.

Coupling Nuts with Sight Hole

Use the sight hole to check for proper thread engagement.

High Hex Nuts

Steel High Hex Nuts

With a height that is 50% taller than standard hex nuts, these nuts provide a larger gripping area for installation with a wrench.

Metric Steel High Hex Nuts

50% taller than standard hex nuts, these metric nuts provide a larger gripping area for installation with a wrench.

Stainless Steel High Hex Nuts

Stainless steel nuts have excellent corrosion resistance in most environments.

Female Thread Adapters

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.

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.

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.

Threaded Rod Eye Nuts

Add an eye nut to threaded rod to hang the rod from rings, hooks, and hangers.

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.
