Value Collection MANL005CP Hex Lock Nut M5 X 0.80 Ss

Product Description

The VALUE COLLECTION MANL005CP is an M5 x 0.80 hex lock nut featuring a nylon insert locking mechanism, manufactured from 18-8 A2 stainless steel with no additional coating. The nylon insert compresses against the mating thread when the nut is driven down, creating resistance to loosening caused by vibration or thermal cycling. At 5.00 millimeters tall with a width across flats of 8.00 millimeters, this nut conforms to DIN 985 dimensional standards. Plumbers, HVAC technicians, electricians, and mechanical contractors reach for stainless steel nylon-insert lock nuts when corrosion resistance and secure fastening are both required in the same joint.

This lock nut is suited for use in corrosive or humid environments where standard carbon steel fasteners are not appropriate. Typical applications include HVAC equipment panels, plumbing fixture mounting, electrical enclosure assembly, pool and spa equipment installations, and general mechanical assemblies subject to vibration. The right-hand thread direction is the global standard orientation, making this nut compatible with conventional right-hand threaded M5 fasteners used across residential and light commercial trade work. Sold individually with a minimum order quantity of 50 pieces.

Key Features

• Nylon insert locking style resists loosening under vibration and thermal cycling without damaging mating threads
• 18-8 A2 stainless steel construction provides corrosion resistance in wet, humid, and mildly chemical environments
• Uncoated finish — no risk of coating delamination contaminating sensitive assemblies
• Conforms to DIN 985 dimensional standard for consistent fit with DIN-spec fasteners
• Right-hand thread direction, M5 x 0.80 pitch — standard metric thread form
• Compact profile: 5.00 mm height, 8.00 mm width across flats

Compatibility

Designed for use with M5 x 0.80 right-hand threaded bolts, screws, and studs conforming to DIN or equivalent metric fastener standards.

Installation Notes

Installation requires an 8 mm wrench or socket to drive the nut to the specified torque for the application and material. Nylon-insert lock nuts are generally rated for single use — the nylon insert deforms during initial installation, and reuse may reduce locking effectiveness. No power shutoff is required for fastener installation, but always follow applicable mechanical codes and equipment manufacturer guidelines when working on energized or pressurized systems.
