Value Collection B10086 Hex Lock Nut M18 X 2.5 Grade 8 Din 985

Product Description

The VALUE COLLECTION B10086 is a metric hex lock nut with a nylon insert, designed to resist loosening under vibration and dynamic loads. Built from Grade 8 steel with a zinc-plated finish, this nut meets DIN 985 specifications and carries a right-hand thread in M18 x 2.5 sizing. The nylon collar deforms around mating threads on installation, creating a friction-based prevailing torque that prevents back-off without the need for thread-locking compounds. Sold in a pack of five, this nut is a standard choice for structural and mechanical assemblies across industrial, commercial, and trade applications.

This nut is suited for metric fastening applications in HVAC equipment frames, mechanical supports, plumbing fixture mounting, and general-purpose equipment assembly. The M18 x 2.5 thread size and DIN 985 standard make it interchangeable with other DIN-compliant hardware in the same spec. The zinc-plated finish offers basic corrosion resistance for indoor and protected outdoor use. Maintenance technicians, millwrights, and installation contractors working with metric hardware will find this nut compatible with standard metric tooling.

Key Features

• Nylon insert locking style resists vibration-induced loosening without adhesives
• Grade 8 steel construction for high-strength fastening applications
• Zinc-plated finish provides corrosion resistance in typical service environments
• Right-hand thread, M18 x 2.5 pitch, conforms to DIN 985 standard
• 27.00 mm width across flats fits standard metric wrenches and sockets
• Pack of 5 units per order

Compatibility

Designed for use with M18 x 2.5 metric bolts and threaded rod conforming to DIN standards. Suitable as a direct replacement or supplemental fastener in any assembly specifying a DIN 985 nylon insert hex lock nut in M18 x 2.5.

Installation Notes

Installation should be performed by a qualified mechanic or technician using a standard metric wrench or socket sized for 27 mm across flats. Nylon insert lock nuts are single-use fasteners and should not be reused after removal, as the nylon collar loses prevailing torque effectiveness once deformed. Always de-energize and de-pressurize any system before replacing fasteners on structural or mechanical components. Follow applicable equipment manufacturer torque specifications and relevant industry standards for the assembly being serviced.
