Value Collection 738230PS Hex Lock Nut M20x2.5

Product Description

The VALUE COLLECTION 738230PS is a metric hex lock nut designed to resist loosening under vibration and dynamic loads. It uses a distorted-thread locking style, which deforms a portion of the thread profile to create mechanical interference with the mating bolt. No secondary locking element such as a nylon insert is required. The nut is manufactured from Class 8 steel with a zinc finish for basic corrosion resistance. Thread size is M20x2.5 with a right-hand thread direction. Width across flats measures 30 millimeters and height measures 20 millimeters. This fastener conforms to DIN 980 and ISO 7042 standards.

This nut is suited for general industrial, mechanical, and structural assemblies where metric fasteners are specified and vibration resistance is required. Typical applications include machinery frames, equipment mounts, and fabricated steel assemblies. It is installed by maintenance technicians, millwrights, and mechanical contractors working on equipment that calls for DIN 980 or ISO 7042 compliant hardware. The zinc finish provides a modest level of protection in dry or mildly humid indoor environments.

Key Features

• Distorted-thread locking design resists loosening without a secondary insert
• Class 8 steel construction for reliable mechanical strength
• Zinc finish provides basic corrosion protection
• Conforms to DIN 980 and ISO 7042 fastener standards
• Right-hand thread direction, M20x2.5 thread size
• 30 millimeter width across flats for standard metric wrench fitment

Compatibility

Designed as an OEM-style replacement or maintenance stock hex lock nut for metric M20x2.5 threaded fastener applications conforming to DIN 980 or ISO 7042 specifications.

Installation Notes

Installation is performed by hand-threading onto a compatible M20x2.5 bolt or stud, then tightening with a standard 30 millimeter metric wrench or socket. Because the distorted-thread design creates increased running torque, apply steady, controlled force during tightening. Do not reuse distorted-thread lock nuts after removal, as repeated cycling degrades the locking effectiveness. Verify thread compatibility with the mating fastener before installation.
