Value Collection KP78604 Hex Lock Nut M12 X 1.75 Grade 8.8 50pk

Product Description

The VALUE COLLECTION KP78604 is a distorted-thread hex lock nut manufactured from Grade 8.8 steel with a zinc-plated finish. It uses a prevailing-torque locking method: the thread form is mechanically distorted during manufacturing, creating resistance against loosening without the need for a secondary locking element such as a nylon insert or a separate locking washer. The nut carries an M12 x 1.75 metric thread in a right-hand direction and conforms to DIN 980 dimensional and performance standards. Licensed trades and industrial maintenance technicians install these nuts wherever vibration resistance is required in metric fastener assemblies.

This nut is suited for general industrial, mechanical, and equipment-assembly applications that call for a DIN 980 all-metal prevailing-torque lock nut in M12 x 1.75. The zinc-plated coating provides a base level of corrosion resistance appropriate for indoor and light-duty outdoor service environments. Sold in a package of 50 units, making it practical for production runs, maintenance stock, or service truck inventory. Mechanical contractors, industrial millwrights, and equipment technicians are the typical end users.

Key Features

• Distorted-thread locking style provides prevailing torque without secondary components
• Grade 8.8 steel construction meets DIN 980 mechanical property requirements
• M12 x 1.75 right-hand thread — standard metric coarse pitch
• Zinc-plated finish for baseline corrosion protection
• DIN 980 fastener standard compliance for dimensional interchangeability
• Packaged in quantities of 50 for production or stocking use

Compatibility

Designed as a DIN 980-compliant all-metal prevailing-torque lock nut for metric M12 x 1.75 threaded fastener applications in industrial, mechanical, and equipment-assembly service.

Installation Notes

Installation is performed by mechanical trades using a standard 19 mm wrench or socket. Ensure mating threads are clean and free of debris before assembly. Because prevailing torque is generated by the distorted thread form, the nut should not be reused after removal, as repeated cycling degrades the locking interference. Consult the applicable equipment manufacturer torque specification for the fastener grade and joint material before final tightening.
