48K427 - Walter 5/8-11 Hex Nut for Backing Pads

Reliable Mounting Hardware for Industrial Abrasives

The Walter Surface Technologies 48K427 Hex Nut is a critical accessory designed to ensure the safe and secure attachment of backing pads to angle grinders. Engineered with precision, this hex nut features a standard 5/8"-11 thread, making it compatible with the vast majority of 4-1/2", 5", and 6" angle grinders used in North American industrial settings. Proper mounting hardware is essential for maintaining the balance and concentricity of abrasive discs, which directly impacts surface finish quality and tool longevity.

Manufactured from high-grade steel, this nut is built to withstand the high torque and vibration associated with heavy-duty grinding and sanding applications. Unlike generic hardware that may strip or deform under stress, the Walter 48K427 maintains its thread integrity over repeated changes, ensuring that your backing pad remains firmly locked in place. This is particularly important when using high-performance resin fiber discs or flap discs where stability is key to preventing pad slippage and ensuring operator safety.

This hex nut is specifically recommended for use with Walter's extensive line of backing pads, including those used for their Coolcut and Topcut sanding discs. Its hexagonal profile allows for easy installation and removal using standard wrenches or grinder spanners, minimizing downtime during abrasive changeovers. Whether replacing a lost component or stocking up on spare parts for the tool crib, the 48K427 provides the reliability professional fabricators expect from Walter Surface Technologies.

In industrial environments, small components often play the biggest roles in safety. A worn or mismatched nut can lead to wheel wobble, excessive vibration, and even catastrophic accessory detachment. By choosing the genuine Walter 48K427, you ensure that your equipment meets the manufacturer's specifications for fit and performance, protecting both the operator and the workpiece.
