Value Collection 812020PR Hex Lock Nut M5x0.8 Din 985

Product Description

The VALUE COLLECTION 812020PR is a metric hex lock nut with a nylon insert locking mechanism, designed for applications requiring secure, vibration-resistant fastening. Built to Class 8 steel construction with a zinc finish for corrosion resistance, this nut conforms to DIN 985 standards. The M5x0.8 thread size and right-hand thread direction make it a standard metric fastener suitable for a wide range of mechanical assemblies. At 8.00 mm across flats and 5.00 mm in height, it provides a compact, reliable hold in confined spaces. Typically installed by maintenance technicians, machine builders, and trade professionals working with metric hardware.

This nylon insert lock nut is suited for use in light to medium-duty mechanical assemblies where vibration, thermal cycling, or movement could cause conventional fasteners to loosen over time. The nylon insert deforms around the mating thread to create prevailing torque without the need for adhesives or separate locking washers. Common applications include equipment panels, machinery frames, HVAC component mounting, and general industrial fabrication. Minimum order quantity is 100 pieces per order, with a package quantity of 1 unit per package as shipped.

Key Features

• Nylon insert locking style provides prevailing torque to resist loosening from vibration

• Class 8 steel construction for reliable strength in light to medium-duty applications
• Zinc finish provides corrosion resistance for general indoor and protected outdoor use
• Conforms to DIN 985 fastener standard for consistent dimensional tolerances
• Compact profile: 8.00 mm width across flats, 5.00 mm height

Compatibility

Designed as an OEM-style metric hex lock nut for use in any assembly requiring an M5x0.8 DIN 985 nylon insert prevailing torque nut. Consult your assembly drawings or fastener specification sheet to confirm thread engagement length and load requirements before substitution.

Installation Notes

Install and remove using a 8.00 mm wrench or socket. Nylon insert lock nuts are intended for single-use in critical applications, as the nylon insert loses prevailing torque effectiveness after repeated removal and reinstallation. Ensure mating bolt threads are clean and free of debris before installation. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being serviced.
