Value Collection 41758 M16x2 Hex Lock Nut Nylon Insert Din 985

Product Description

The VALUE COLLECTION 41758 is an M16x2 nylon insert hex lock nut manufactured from Class 8 steel with a zinc-plated finish. Designed to resist loosening under vibration and dynamic loads, it uses a nylon insert collar that deforms around the thread flanks to create a prevailing-torque locking action without requiring a separate locking washer or thread-locking compound. The zinc plating provides baseline corrosion resistance suitable for general indoor and light outdoor applications. Right-hand thread direction follows standard convention. This fastener conforms to DIN 985 and is sold individually with a minimum order of 25 units.

This nut is used across a wide range of mechanical assembly applications where vibration resistance is required. Typical installations include structural steel connections, HVAC equipment frames, pump mounts, fan assemblies, and general industrial machinery. It is suited for use by millwrights, pipefitters, HVAC technicians, and maintenance professionals working in commercial and light industrial environments. The metric M16x2 thread size makes it compatible with standard metric bolt and stud stock of the same pitch.

Key Features

• Nylon insert locking action resists loosening from vibration without additional hardware
• Class 8 steel construction provides high strength for demanding fastening applications
• Zinc-plated finish offers corrosion resistance for general service environments
• Right-hand thread, DIN 985 standard for broad interchangeability
• M16x2 metric thread size with 24.00 mm width across flats
• 16.00 mm height provides adequate nut engagement depth for the thread size

Compatibility

Designed as an OEM-style replacement or service fastener for metric M16x2 threaded bolts and studs conforming to DIN 985 dimensional standards in mechanical and industrial assemblies.

Installation Notes

Installation should be performed by qualified mechanical or trade personnel using an appropriately sized wrench matched to the 24.00 mm across-flats dimension. Confirm the mating bolt or stud is also M16x2 pitch before assembly. Nylon insert lock nuts are generally considered single-use; once the nylon collar has been fully engaged and removed, replace with a new nut to maintain reliable locking torque. De-energize and lock out any equipment before servicing fasteners on powered machinery.
