Value Collection 2-MN-8 Hex Lock Nut M8x1.25 316 Ss Din 985

Product Description

The Value Collection 2-MN-8 is a metric hex lock nut with a nylon insert locking mechanism, manufactured from Grade 316 A4 stainless steel with a bright uncoated finish. The nylon insert creates interference with the mating thread, resisting loosening caused by vibration or dynamic loading without damaging the fastener it engages. The M8x1.25 thread size and DIN 985 standard construction make this a reliable choice for stainless fastening applications in corrosive or marine environments. Installers in plumbing, HVAC, marine, and food-service trades reach for 316-grade stainless hardware specifically for its superior chloride resistance compared to 304-grade alloys.

This nylon insert lock nut is suited for residential and commercial applications where vibration resistance and corrosion resistance are both required. Typical installations include outdoor mechanical equipment, marine hardware, coastal plumbing assemblies, chemical processing supports, and pool and spa equipment mounting. The right-hand thread direction is standard for most bolt and stud pairings. Supplied in individual piece quantities with a minimum order of 25 units.

Key Features

• Nylon insert locking style resists vibration-induced loosening without thread damage
• Grade 316 A4 stainless steel offers superior corrosion resistance in chloride-heavy and marine environments
• M8x1.25 right-hand thread per DIN 985 standard
• Bright uncoated finish preserves stainless surface properties
• 8.00 mm height and 13.00 mm width across flats for standard tooling fit

Compatibility

Designed as an OEM-style replacement or direct-use hex lock nut for any M8x1.25 right-hand threaded bolt or stud requiring a DIN 985 nylon insert lock nut in stainless steel grade 316 A4.

Installation Notes

Installation is performed with standard metric wrenches sized to the 13.00 mm width across flats. Power down or de-energize any equipment before fastener service on electrical or mechanical assemblies. The nylon insert is a single-use locking feature — once fully torqued and removed, the insert may not provide the same locking force if reused. Follow applicable mechanical and structural codes for the assembly type when determining fastener torque requirements.
