The Differences Between Round, Square, and Hex Acme Nuts

How do you know whether you need a round, square, or hex Acme nut?  While all Acme nuts are designed to provide reliable performance and smooth motion when paired with Acme screws, each shape offers its own advantages.

Round Acme Nuts: Versatility and Simplicity

Round Acme nuts are often the go-to choice for applications where space is limited or where the nut will be rotated by hand. Their circular shape allows for easy installation and removal. We offer round Acme nuts in a variety of materials, including low carbon steel, stainless steel, brass, and aluminum, giving our customers flexibility to meet their specific needs.

Square Acme Nuts: Strength and Torque

Square Acme nuts are known for their durability and for being able to handle higher torque loads. The flat sides allow for better grip with wrenches or other tools, making them a preferred choice in heavy-duty machinery and many other industrial applications. Square nuts also resist loosening under vibration better than some other designs, making them ideal for harsh environments. Notably, our square nuts are stocked in multiple materials and can be customized to suit your specifications.

Hex Acme Nuts: Accessibility and Convenience

Hex Acme nuts combine strength with ease of use, thanks to their six-sided design. The additional sides provide more angles for a wrench or socket to engage, making installation quicker and more efficient than square nuts in tight spaces. Hex nuts are versatile and used in a wide range of industries. As such, they are particularly effective in applications where both torque and accessibility are important. Our hex Acme nuts are available in standard sizes as well as many non-standard options, ensuring we can meet the needs of any project.

Ultimately, when choosing between round, square, and hex Acme nuts, it’s important to consider your application, the level of torque required, and the space constraints.
