Value Collection 556256PS M18x1.5 Class 8 Hex Nut Zinc-plated

Product Description

The VALUE COLLECTION 556256PS is a metric fine-thread hex nut designed for bolted assemblies requiring controlled clamp load and corrosion resistance. Manufactured from Class 8 steel with a zinc-plated finish, this nut carries an M18 x 1.50 thread size and measures 27 millimeters across flats and 15 millimeters in height. It conforms to DIN 934 and ISO 4032 fastener standards, making it a direct fit wherever those standards are called out on engineering drawings or in maintenance specifications. Machinists, millwrights, pipefitters, and general maintenance technicians use this nut in structural, mechanical, and equipment-mounting applications that demand a reliable metric fine-thread fastener.

This hex nut is suited for residential and commercial maintenance, industrial equipment assembly, and mechanical repair work where metric fine-thread fasteners are specified. The fine 1.50 mm pitch provides better resistance to vibration-induced loosening compared to coarse-thread equivalents, making it a practical choice in machinery, automotive, and equipment service environments. Right-hand thread engagement follows standard practice for the vast majority of threaded fastener installations.

Key Features

• M18 x 1.50 metric fine thread for improved vibration resistance over coarse-thread alternatives
• Class 8 steel construction provides solid mechanical strength for general-purpose bolted joints
• Zinc-plated finish offers baseline corrosion protection in typical shop and field environments
• Conforms to DIN 934 and ISO 4032 fastener standards
• Right-hand thread direction matches standard assembly practice
• 27 mm across flats accepts standard metric wrenches and sockets

Compatibility

Designed as a standard DIN 934 and ISO 4032 compliant M18 x 1.50 hex nut, compatible with any M18 x 1.50 metric fine-thread bolt or stud conforming to those standards.

Installation Notes

Installation is performed by hand-starting the nut onto a clean, undamaged M18 x 1.50 threaded fastener, then torquing to the value specified for Class 8 hardware in the applicable engineering or equipment manual. Use a calibrated torque wrench and the correct 27 mm socket or open-end wrench. Inspect threads for damage or contamination before assembly. Do not apply thread-locking compounds unless specified, as improper use can affect clamp load.
