Value Collection 4549 Hex Nut M10 X 1.25 Class 8 Zinc 100pk

Product Description

The VALUE COLLECTION 4549 is a metric fine-thread hex nut designed for general mechanical fastening applications requiring a reliable, corrosion-resistant connection. Manufactured from Class 8 steel with a zinc-plated finish, this nut conforms to JIS B 1181 fastener standards. It features an M10 x 1.25 thread profile with a right-hand thread direction, a width across flats of 14 mm (0.551 inches), and a height of 8 mm (0.315 inches). Licensed trades and maintenance professionals use this nut wherever metric fine-thread fastening is required in machinery, automotive, and industrial assemblies. This listing covers a package quantity of 100 nuts.

This nut is suited for residential, commercial, and industrial applications where metric fine-thread hardware is specified. The M10 x 1.25 pitch is commonly used in automotive drivetrain components, precision machinery, and mechanical assemblies where finer thread engagement and reduced vibration loosening are priorities over a standard M10 x 1.5 coarse-thread fastener. Maintenance technicians, millwrights, and automotive service professionals are the primary installers. The zinc plating provides a base level of corrosion resistance appropriate for general indoor and light outdoor environments.

Key Features

• M10 x 1.25 metric fine-thread profile with right-hand thread direction
• Class 8 steel construction for reliable load-bearing capacity
• Zinc-plated finish for corrosion resistance in general-duty environments
• Conforms to JIS B 1181 fastener standard
• 14 mm width across flats, compatible with standard metric wrenches and sockets
• Packaged in quantities of 100 for shop and field stocking

Compatibility

Designed as an OEM-style replacement or general-use metric fine-thread hex nut for mechanical assemblies specifying an M10 x 1.25 thread, Class 8 steel, and JIS B 1181 compliance.

Installation Notes

Installation is performed by hand-threading onto a compatible M10 x 1.25 male-threaded fastener before final torquing with an appropriate metric wrench or socket. Always verify thread pitch before installation, as M10 x 1.25 and M10 x 1.5 nuts are not interchangeable. Follow applicable mechanical or automotive service specifications for torque values based on the joint material and application. Inspect threads for damage or contamination before assembly to ensure full thread engagement.
