Value Collection 812090PR Hex Lock Nut M18x2.5

Product Description

The VALUE COLLECTION 812090PR is a metric hex lock nut with a nylon insert locking style, designed to resist loosening under vibration and dynamic loads. Built from Class 8 steel with a zinc finish for corrosion resistance, this nut conforms to DIN 985 standards. The M18x2.5 right-hand thread pitch suits a wide range of metric fastening applications. At 18.50 millimeters in height and 27.00 millimeters across the flats, it is sized for use in structural, mechanical, and equipment assembly work. Licensed tradespeople and assembly technicians install this hardware in industrial, commercial, and trade construction contexts.

This hex lock nut is suited for metric bolted connections in mechanical assemblies, equipment frames, HVAC structural supports, plumbing fixture mounts, and general trade applications requiring a prevailing-torque locking fastener. The nylon insert engages the bolt threads on final turns, creating resistance that prevents self-loosening without the need for adhesives or additional locking hardware. Typical applications include securing brackets, flanges, and panels where vibration or repeated thermal cycling may compromise standard nuts.

Key Features

• Nylon insert locking style provides prevailing-torque resistance without adhesives
• M18x2.5 right-hand metric thread conforms to DIN 985 standard
• Class 8 steel construction for reliable load-bearing strength
• Zinc finish adds corrosion resistance for indoor and protected outdoor use
• 27.00 mm width across flats fits standard metric wrenches
• 18.50 mm nut height provides adequate thread engagement depth

Compatibility

Designed as a prevailing-torque replacement or new-installation lock nut for M18x2.5 metric bolts and studs conforming to DIN 985 specifications.

Installation Notes

Install and remove with an appropriate metric wrench or socket sized for 27.00 mm across flats. Nylon insert lock nuts are single-use by design — the nylon deforms on first installation, and reuse reduces locking effectiveness. Always de-energize or shut down associated equipment before servicing fastened assemblies. Follow applicable mechanical and structural codes for fastener torque class and joint requirements.
