M3.5 Adapters | McMaster-Carr

In addition to joining male- and female-threaded parts, these adapters can increase or decrease metric thread sizes and change the thread pitch. You can also use the smaller adapters as threaded standoffs, positioning and separating circuit boards and other components in assemblies.

Black-Oxide Steel—Choose black-oxide steel adapters to match the aesthetics of your system or for their mild corrosion resistance. The finish won't chip or rub off. They resist rust in indoor and dry environments, but avoid using them in corrosive environments.

Zinc-Plated Steel—Zinc-plated steel adapters are a good option in dry environments. The zinc plating prevents the steel from corroding until the plating wears away.

Aluminum—At about a third of the weight of steel adapters, aluminum adapters are the lightest we offer. They resist corrosion in wet environments.

18-8 Stainless Steel—18-8 stainless steel adapters resist corrosion caused by water. They're good for wet and damp environments but will corrode when exposed to salt water and other chloride solutions.

ASTM A108, ASTM A582, and ASTM B633—Adapters that meet ASTM specifications are made from or plated with materials that adhere to specific standards for chemical and physical properties, such as hardness.

Metric-to-Metric Male Hex Thread Adapters

Twist these adapters onto female metric threads to change pitch or switch thread sizes. They can also be used as standoffs to make space between parts. Tighten or loosen with a wrench.

Black-Oxide Steel—Black oxide steel adapters have a black finish that won’t chip or rub off. They will not rust in dry or indoor environments, but will corrode if used outdoors.

Zinc-Plated Steel—Zinc-plated steel adapters should be used in mostly dry environments. The zinc plating offers temporary rust protection, but once it wears away the steel will rust.

Aluminum—At one third the weight of steel, aluminum adapters are the lightest option. They will not rust in damp or humid environments, but they will corrode if left in water.

18-8 Stainless Steel—18-8 stainless steel adapters can be used in wet environments, but chemicals or salt water will cause staining and rust spots.

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, these adapters have a hex-shaped body, so you can tighten them with a standard wrench. You can also use them to change thread pitch or convert a male-threaded connection to a female-threaded connection. Small adapters can work as threaded standoffs, positioning and separating circuit boards and other components in assemblies.

Black-Oxide Steel—Black-oxide steel adapters have a finish that won’t chip or rub off. They match the aesthetics of many systems. They resist rust in indoor and dry environments but will degrade in outdoor and highly corrosive environments.

Zinc-Plated Steel—Zinc-plated steel adapters are a good option in dry environments. The zinc plating prevents the steel from corroding until the plating wears away.

Aluminum—Aluminum adapters are about one third of the weight of steel adapters. They resist corrosion in wet environments.

18-8 Stainless Steel—18-8 stainless steel adapters resist corrosion in wet environments. However, they will corrode when exposed to salt water and other chloride solutions.

Inch-to-Metric Male-Female Hex Thread Adapters

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench. You can also use them to increase or reduce your thread size, or to create space between parts in an assembly.

Zinc-Plated Steel—Zinc-plated steel adapters should be used in mostly dry environments. The zinc plating offers temporary rust protection, but once it wears away the steel will rust.

Aluminum—At one third the weight of steel, aluminum adapters are the lightest option. They will not rust in damp or humid environments, but they will corrode if left in water.

18-8 Stainless Steel—18-8 stainless steel adapters can be used in wet environments, but chemicals or salt water will cause staining and rust spots.

Inch-to-Metric Male Hex Thread Adapters

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.

You can also use these adapters to change the gender of a mating part or increase or decrease its thread size. The small sizes work as standoffs, positioning and separating circuit boards and other components in assemblies.

Zinc-Plated Steel—Zinc-plated steel adapters are a good option in dry environments. The zinc plating prevents the steel from corroding until the plating wears away.

Aluminum—At about a third of the weight of steel adapters, aluminum adapters are the lightest we offer. They resist corrosion in wet environments.

Rod End Nuts

Attach these nuts to rods, pipes, and tubes to make pivoting and hinge movements where misalignment is not a concern. They’re often used to control air- and hydraulic-powered arms as well as other components in power transmission systems. Made of zinc-plated steel, these nuts resist being dislodged. They’re heavy, however, and may corrode over time as the plating wears down.

Male-Female Threaded Hex Standoffs

Separate, position, and connect components. These standoffs are your go-to choice for everything from stacking boards and creating space for airflow to mounting components on chassis or enclosures. To securely tighten standoffs, grip the flat sides of the hex body with a wrench.

Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these standoffs resist rusting. They're strong enough for most jobs, but won't withstand stress as well as steel.

Low-Profile Rectangular Weld Nuts

Weld permanent threads in channels and other tight spaces without adding a barrel bump that gets in the way. These nuts have a short barrel that tucks under low surfaces and a slim footprint that fits between narrow channel walls.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

Number of Projections—More projections lead to more consistent welds by concentrating heat and protecting the threads from deforming.

Offset-Barrel Low-Profile Rectangular Weld Nuts

Add permanent threads on corners and near edges. With a slim base and a short, offset barrel, these weld nuts fit in tight spaces such as channels and low-clearance areas.

Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.

Zinc-Plated Steel—A step up from plain steel, these nuts withstand occasional exposure to moisture. Weld them to uncoated steel surfaces. If MIG or TIG welding, grind the zinc plating off the part of the nut you intend to weld.

Number of Projections—More projections lead to more consistent welds by concentrating heat and protecting the threads from deforming.
