Value Collection 526056PS M18 X 2.50 Zinc-plated Jam Nut

Product Description

The VALUE COLLECTION 526056PS is a Grade 2H steel jam nut designed for M18 x 2.50 threaded fastener applications. This hex-profile jam nut features a zinc-plated finish for corrosion resistance and measures 27 millimeters across flats with a height of 9 millimeters. Its low-profile design makes it a standard choice when a locking or spacing nut is needed in tight clearance conditions. Right-hand thread direction conforms to DIN 439 and ISO 4035 standards. Technicians working in mechanical assembly, structural fastening, and equipment maintenance will find this nut suitable for a wide range of production and maintenance tasks.

This jam nut is suited for industrial and commercial fastening applications where an M18 x 2.50 threaded rod, bolt, or stud is present. The low-profile hex nut is commonly used in conjunction with a primary nut to lock a fastener assembly in place or as a standalone nut where reduced axial space is required. Fabricators, millwrights, and maintenance mechanics typically encounter this type of fastener in structural assemblies, machinery mounting, and equipment installations. The zinc plating provides moderate environmental protection suitable for indoor and sheltered outdoor use.

Key Features

• Grade 2H steel construction meets strength requirements for heavy-duty fastening applications
• Zinc-plated finish provides corrosion resistance for general-purpose use
• Low-profile jam nut design at 9 millimeters height for tight-clearance installations
• Right-hand thread direction, M18 x 2.50 thread pitch
• Conforms to DIN 439 and ISO 4035 fastener standards
• 27 millimeters across flats, compatible with standard metric wrenches

Compatibility

Designed for use on M18 x 2.50 threaded fasteners including bolts, rods, and studs in applications conforming to DIN 439 and ISO 4035 standards.

Installation Notes

Installation is performed with a standard metric open-end or combination wrench sized for 27 millimeters across flats. Power down or de-energize any associated equipment before working on fastener assemblies in electrical or mechanical systems. When used as a jam nut, torque the primary nut first, then back-torque the jam nut against it to secure the assembly. Do not substitute this low-profile jam nut for a full-height structural nut where full load-rated thread engagement is required.
