Two-Width Nuts.

What are Two-Width Nuts?

Two-width nuts are specialised nuts featuring a circular body with two opposing flat sides. This unique shape enables the round nuts with two flat sides to be engaged securely with a wrench or spanner, offering controlled torque application.

Unlike traditional hexagonal nuts with six sides, two-width threaded nuts with two flat sides are particularly advantageous in a range of applications where space is restricted or where exotic materials make it difficult to achieve a hex nut shape. They are commonly utilised in environments such as kilns, cooking equipment and sensor housings, where reliability under high temperatures or chemical exposure is critical.

How Two-Flat Nuts Work

Two-flat nuts function by threading onto a compatible precision screw or threaded stud, securing two or more components together. The two flat sides of the nut provide defined gripping surfaces, allowing for efficient tightening and loosening using standard hand tools.

This design is ideal where standard hex nuts may not be feasible due to spatial limitations or material considerations. Their performance remains consistent even in demanding conditions, such as extreme heat or chemically reactive environments.

Materials Two-Width Nuts Are Made From

Accu’s range of two-width nuts is available in material options tailored to specific application needs.

• Ceramic: Exceptionally high temperature resistance, capable of withstanding temperatures up to 1500°C. Ideal for kiln and high-heat industrial environments.
• PTFE (Polytetrafluoroethylene): Offers excellent corrosion resistance and a low-friction surface, making it suitable for use in cooking equipment and sensor assemblies exposed to chemicals.

Sizes and Types of Two-Width Nuts Available

Two Width Nuts are offered in a range of metric sizes to accommodate varying installation requirements from M3 (3mm) to M10 (10mm). Their round body with two opposing flat sides is optimised for use with standard spanners or adjustable wrenches.

This size range ensures versatility across different mechanical and industrial systems, allowing for secure fastening in compact and high-performance assemblies.

FAQs

Q: What are the benefits of using two-width nuts over standard hex nuts?

A: Two-width nuts provide a compact fastening solution with a smoother profile, ideal for space-constrained or applications requiring exotic materials, which are hard to manufacture by nature. Their flat sides still allow for easy tool engagement.

Q: Can two-width nuts handle high temperatures?

A: Yes, our ceramic two-width nuts are engineered to withstand temperatures up to 1500°C, making them suitable for high-heat environments such as kilns.

Q: Are two-width nuts chemically resistant?

A: PTFE two-width nuts offer excellent resistance to chemicals, ensuring durability in corrosive environments like cooking appliances and sensor equipment.

Q: How do I install a two-width nut?

Installation involves threading the nut onto a compatible bolt or stud and tightening it using a torque wrench or spanner applied to the two flat sides. Care should be taken to ensure the ceramic variants are installed correctly.
