Value Collection 41760 M20 Hex Lock Nut Class 8 Din 985

Product Description

The VALUE COLLECTION 41760 is a metric hex lock nut with a nylon insert locking mechanism, manufactured from Class 8 steel with a zinc-plated finish. It carries a right-hand thread in M20 x 2.50 and conforms to DIN 985 standards. The nylon insert creates interference with the mating thread to resist loosening under vibration and dynamic loads without damaging the fastener or the mating bolt. At 20.00 millimeters in height with a 30.00 millimeter width across flats, this nut fits standard M20 tooling. Maintenance technicians, millwrights, and assembly professionals install this type of fastener across a wide range of structural and mechanical applications.

This nut is suited for metric fastener assemblies in industrial, commercial, and trade environments where vibration resistance is required. Typical applications include mechanical equipment mounting, structural steel connections, and machinery assembly where a prevailing-torque lock nut is specified. The DIN 985 standard makes it a direct-fit option for any application calling out that specification. It ships in a package quantity of one with a minimum order quantity of 25 units.

Key Features

• Nylon insert provides prevailing-torque locking without thread damage
• Class 8 steel construction for high tensile and proof load ratings
• Zinc-plated finish for corrosion resistance in general-duty environments
• Right-hand thread direction, M20 x 2.50 pitch
• Conforms to DIN 985 fastener standard
• Metric system of measurement for compatibility with metric bolt assemblies

Compatibility

Designed as a DIN 985-compliant nylon insert hex lock nut for metric M20 x 2.50 threaded fastener assemblies in industrial and mechanical applications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using an appropriate metric wrench or socket sized for a 30.00 millimeter width across flats. Always ensure the mating bolt thread condition and cleanliness before installation, as debris or thread damage can compromise the nylon insert locking function. The nylon insert is rated for single use in critical applications — reuse on a replacement bolt may reduce locking effectiveness. Follow applicable equipment manufacturer torque specifications and relevant standards for the assembly.
