What are Philidas Industrial Nuts?

A Philidas industrial nut is a specialised, self-locking all-metal nut engineered for high-stress applications. It stands as a reliable option in demanding settings where vibration and the risk of coming loose need to be minimised. Accu maintains a high regard for these fasteners and also provides the Philidas turret nut variant.

How do Philidas Industrial Nuts Work?.

Philidas industrial nuts incorporate a unique locking mechanism located in the collar. When tightened, the bolt's threads deform the upper portion of the nut, generating a wedge-like action. This creates a locking force that ensures the nut remains secure, even under vibration or load, a mechanism similar to Aerotight nuts.

What Are Philidas Industrial Nuts Made From?.

These nuts are manufactured from premium A2-70 and A4-80 stainless steel, ensuring durability and resistance to corrosion. Unlike nylon-based locking options, the all-metal construction of Philidas Industrial Nuts offers enhanced robustness and heat resistance.

Accu also offers an additional blackening service, AccuBlack, suitable for applications requiring a satin black finish, such as aerospace or architecture.

What Sets Philidas Industrial Nuts Apart from Philidas Turret Nuts?.

While both types offer locking features, Philidas industrial nuts excel in their overall robustness, making them versatile across various industries. Philidas turret nuts on the other hand are typically recommended for cases requiring even higher levels of reusability.


What tools are needed for installation?.

Generally, a standard spanner or socket set will suffice for installation. For high-volume or precision-driven projects, torque wrenches can be employed.

Can Philidas industrial nuts be re-used?.

Yes, they are designed for reusability although if you know this will be an occurrence, we’d recommend the turret nut variant. Always perform a pre-use inspection for any signs of wear or damage before attempting to re-use any fastener.

Are Philidas industrial nuts made to any industry standards?.

Indeed, they conform to industry standards, notably ISO 2320 and 898-2 for BS 4929, ensuring their quality, safety, and performance.

Can environmental factors impact Philidas industrial nuts?.

The A2-70 and A4-80 stainless steel these nuts are built from can endure various environmental conditions, including high temperatures and exposure to fluids. For extreme conditions, selecting the appropriate material grade is crucial.
