48K340 - Walter M6 DIN 985 Nylon Insert Hex Lock Nut

Reliable Fastening for Industrial Equipment

The Walter 48K340 Hex Nut M6 DIN 985 is a critical replacement fastener designed to maintain the structural integrity and operational safety of your Walter Surface Technologies equipment. Manufactured to the strict DIN 985 standard, this hex nut features a specialized nylon insert ring located at the top of the threads. This insert acts as a prevailing torque locking mechanism, deforming elastically over the mating bolt threads to create a tight, friction-based seal that resists loosening.

In the context of power tools and abrasive equipment, vibration is a constant challenge. Standard nuts can back off over time due to the high-frequency oscillations generated by grinding, sanding, and cutting operations. The 48K340 addresses this issue specifically; the nylon collar dampens vibration and prevents the nut from rotating freely, ensuring that backing pads, guards, and internal components remain securely fastened. This component is essential for maintaining the precision and safety of your Walter tools.

This M6 nut is compatible with a variety of Walter power tools and accessories that utilize metric fasteners. Whether used for routine maintenance or an emergency repair, using genuine Walter hardware ensures that the metallurgical properties and dimensional tolerances match the original equipment specifications. This attention to detail prolongs the lifespan of the tool and protects the operator from potential hazards associated with loose equipment parts.

Technical Specifications

The nut features a standard M6 metric thread pitch, making it compatible with a wide range of industrial bolts and studs. The hexagonal drive allows for easy installation with standard wrenches or sockets. As a single-use locking device, it is recommended to replace DIN 985 nuts after removal to ensure maximum locking efficiency, as the nylon insert's memory may degrade after the first installation.
