MroMax M56 x 2mm Carbon Steel Retaining Four-Slot Slotted Round Nuts

Description

Product Overview

The MroMax M56 x 2mm carbon steel retaining four‑slot slotted round nut is engineered for high‑strength fastening in a wide range of industrial environments. Constructed from premium carbon steel, the nut undergoes an oxidized black coating process that significantly improves corrosion resistance while maintaining the material’s inherent toughness. With an outer diameter of 85 mm and a height of 12 mm, the nut provides ample surface area for secure engagement with mating components, reducing the risk of slippage under heavy loads.

Precision machining ensures a consistent thread pitch of 2 mm (0.08 in), delivering a tight, repeatable fit that is essential for applications such as roller bearings, axial shafts, and pump valves. The four‑slot design allows for easy installation and removal using standard tools, while the internal threading guarantees a reliable connection that can withstand vibration and cyclic stresses common in heavy‑duty machinery.

Dimensions are carefully controlled to meet industry standards: the threaded size is M56 x 2mm, the outer diameter measures 85 mm (3.35 in), and the overall height is 12 mm (0.47 in). These specifications make the nut compatible with a broad spectrum of standard components, simplifying inventory management for maintenance teams and reducing the need for multiple part numbers.

Usage

In the field, the MroMax four‑slot slotted round nut excels in environments where reliability and ease of service are paramount. Its robust construction makes it suitable for use in high‑temperature settings, such as pump housings and motor assemblies, where exposure to oil, coolant, or other aggressive fluids is routine. The nut’s design also accommodates rapid assembly and disassembly, which is valuable during routine maintenance or emergency repairs where downtime must be minimized.

Typical applications include securing roller bearings on shafts, anchoring axial components in hydraulic systems, and fastening valve assemblies in process equipment. The nut’s four‑slot configuration provides a convenient access point for torque wrenches or socket tools, enabling technicians to achieve the correct tightening torque without the need for specialized equipment. This versatility makes the product a go‑to choice for mechanical engineers, plant maintenance crews, and OEM manufacturers alike.

FAQ

What size thread does the M56 nut use?

The nut features an M56 thread with a 2 mm pitch, which is standard for large‑diameter fasteners used in heavy‑duty applications.

Is the black coating purely decorative?

No. The black oxide coating is applied to improve corrosion resistance and extend the service life of the nut, especially in environments exposed to moisture or chemicals.

Can this nut be used with stainless steel bolts?

Yes, the nut is compatible with stainless steel bolts of the same M56 x 2 mm specification, providing a reliable joint while preventing galvanic corrosion due to the protective coating.

What is the recommended torque setting for installation?

For optimal performance, we recommend tightening the nut to a torque of 120 Nm (88 lb‑ft). Always refer to the equipment manufacturer’s guidelines for specific torque requirements.

How many nuts are included in the package?

Each package contains a single MroMax M56 x 2mm four‑slot slotted round nut, packaged securely to protect the coating and threads during shipping.
