Value Collection KP78600 Hex Lock Nut M5 X 0.80 Grade 8.8

Product Description

The VALUE COLLECTION KP78600 is a metric hex lock nut engineered to resist loosening under vibration and dynamic load conditions. Built to DIN 980 standards, it uses a distorted-thread locking style that creates interference between the nut and bolt threads without requiring a separate insert or patch. The fastener is manufactured from Grade 8.8 steel with a zinc-plated finish for basic corrosion resistance. Thread size is M5 x 0.80, right-hand thread. Height is 5.10 mm and width across flats is 8.00 mm. These are sold in packages of 50 and are appropriate for mechanical assemblies where vibration resistance is required.

This lock nut is suited for use in light mechanical, HVAC equipment, plumbing hardware, and general industrial assembly applications where metric fasteners and DIN-standard components are specified. The distorted-thread design eliminates the need for nylon inserts, making it viable in applications with elevated temperatures that would compromise an all-nylon prevailing torque nut. Installers working on equipment requiring DIN 980 compliance will find this nut a direct-fit replacement or new-installation option.

Key Features

• Distorted-thread locking style provides prevailing torque without inserts or patches
• Grade 8.8 steel construction for reliable mechanical strength in metric fastener applications
• Zinc-plated finish adds a baseline level of corrosion resistance
• Conforms to DIN 980 fastener standard
• Right-hand thread direction, M5 x 0.80 pitch
• Packaged in quantities of 50 to support production and service work

Compatibility

Designed as a DIN 980-compliant M5 x 0.80 metric hex lock nut suitable for use with standard M5 right-hand threaded bolts and studs in mechanical and equipment assembly applications.

Installation Notes

Installation is performed by hand tool or power driver with an 8 mm wrench or socket. Power down or de-energize any equipment before servicing fasteners on live assemblies. Because distorted-thread lock nuts are designed as prevailing-torque fasteners, they should be replaced rather than reused after removal to ensure consistent clamping force. Consult applicable equipment service manuals for torque specifications relevant to the assembly.
