Value Collection 556056PS Hex Nut M18 X 2.50 Class 8

Product Description

The VALUE COLLECTION 556056PS is a Class 8 steel hex nut with a zinc-plated finish, sized for M18 x 2.50 right-hand thread applications. It meets DIN 934 and ISO 4032 fastener standards, making it a reliable choice for structural and mechanical assemblies that demand consistent clamping force. The zinc plating provides a baseline level of corrosion resistance suitable for general-purpose indoor and light outdoor use. At 27 millimeters across the flats and 15 millimeters in height, it is sized to accept standard M18 wrenching. Installed by mechanics, millwrights, pipefitters, and general trade professionals wherever a metric hex nut is required.

This hex nut is suited for a wide range of commercial and industrial fastening applications, including equipment assembly, structural connections, and maintenance work. The Class 8 material grade indicates a medium-high strength rating appropriate for applications with moderate load requirements. Right-hand thread direction is standard for the vast majority of mechanical assemblies. The DIN 934 and ISO 4032 standards ensure dimensional conformance for interchangeability across metric fastener systems.

Key Features

• M18 x 2.50 thread size with right-hand thread direction
• Class 8 steel construction for medium-high strength fastening
• Zinc-plated finish for baseline corrosion resistance
• Conforms to DIN 934 and ISO 4032 fastener standards
• 27 millimeters across flats for standard M18 wrench sizing
• 15 millimeters in height for full thread engagement on standard bolt lengths

Compatibility

Designed for use with M18 x 2.50 metric bolts and threaded rod in general-purpose mechanical and structural assemblies conforming to DIN 934 or ISO 4032 specifications.

Installation Notes

Installation is performed by hand-threading onto a compatible M18 x 2.50 bolt or stud, then torquing with an appropriately sized wrench or socket. Always ensure mating thread condition and pitch match before final assembly. Do not apply excessive force beyond the rated torque for Class 8 fasteners, as this can strip threads or induce bolt fatigue. Use thread lubricant or anti-seize only when specified for the application.
