Value Collection 557066PR Hex Nut M30 X 3.50 Class 8

Product Description

The VALUE COLLECTION 557066PR is a Class 8 steel hex nut with a metric M30 x 3.50 thread and a bright uncoated finish. It conforms to DIN 934 and ISO 4032 fastener standards, making it a direct fit for general industrial and structural bolting applications. The nut features a right-hand thread, a width across flats of 46 mm, a width across points of 50.85 mm, and a height of 24 mm. Class 8 material grade provides reliable load-bearing performance in medium- to high-strength fastener assemblies. Installation requires a standard 46 mm hex wrench or socket.

This hex nut is suited for industrial maintenance, equipment assembly, structural fabrication, and general mechanical applications where a large-diameter metric fastener is required. The uncoated bright finish is appropriate for indoor or controlled-environment use. Machinists, millwrights, maintenance technicians, and fabricators working with M30-threaded rod, bolts, or studs will find this nut a standard fit. It does not meet military specifications and is intended for commercial and industrial use.

Key Features

• M30 x 3.50 right-hand thread for compatibility with standard metric M30 fasteners
• Class 8 steel construction provides solid medium-to-high strength performance
• 46 mm width across flats matches standard DIN 934 tooling requirements
• Conforms to DIN 934 and ISO 4032 fastener standards
• Bright uncoated finish — suitable for dry or controlled indoor environments

Compatibility

Designed for use with M30 x 3.50 metric bolts, studs, and threaded rod in industrial and structural assemblies conforming to DIN 934 or ISO 4032 specifications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians familiar with metric fastener torque requirements for Class 8 hardware. Use a properly sized 46 mm hex socket or open-end wrench to avoid rounding the flats. De-energize or shut down equipment before servicing fastened assemblies under load. Do not use impact tools without verified torque control to prevent over-tightening.
