About half the strength of medium-strength steel coupling nuts, these nuts are for light duty fastening applications.
For light duty applications, choose these metric-sized coupling nuts.
The left-hand threads on these coupling nuts resists loosening from counterclockwise vibration. Use in light duty applications.
Made from Grade 5 steel, these inch-sized coupling nuts are suitable for most applications.
Choose these locknuts to fasten standard metric threads. They’re Class 8 steel, so they can be used in most fastening applications.
Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.
These metric-sized coupling nuts are Class 10 steel, so they’re about 25% stronger than medium-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.
These coupling nuts have good chemical resistance.
These metric coupling nuts have good chemical resistance.
More corrosion resistant than 18-8 stainless steel coupling nuts, these nuts have excellent resistance to chemicals and salt water.
More corrosion resistant than 18-8 stainless steel coupling nuts, these metric nuts have excellent resistance to chemicals and salt water.
One-third the weight of steel, aluminum coupling nuts resist corrosion in wet environments.
Brass coupling nuts are corrosion resistant in wet environments and electrically conductive.
Plastic coupling nuts are chemical resistant, nonconductive, and lightweight.
Known for their strength, steel coupling nuts are available with a corrosion-resistant finish.
Stainless steel coupling nuts have excellent corrosion resistance in most environments.
A smooth rounded body provides a finished look.
Use the sight hole to check for proper thread engagement.
Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench.
Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.
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.
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.
Adapt your shaft to a threaded end without having to machine threads onto your shaft.
