48R499 - Replacement Screw Cap for 3-Inch Backing Pads

Genuine Replacement Hardware for Walter Abrasive Systems

The Walter 48R499 Duplex Screw Cap is a critical maintenance component designed for industrial metalworking environments utilizing Walter Surface Technologies' 3-inch abrasive systems. In high-throughput MRO and fabrication settings, the integrity of abrasive mounting hardware is paramount for both safety and performance. This screw cap serves as the primary locking mechanism for securing 3-inch sanding and grinding discs to their respective backing pads, ensuring that the consumable remains concentric and stable under the high torque and RPM of pneumatic or electric die grinders.

Manufactured to Walter's precise engineering standards, this screw cap features durable threading and a robust geometry designed to withstand the vibration and thermal stresses associated with continuous grinding operations. Over time, mounting hardware can suffer from thread wear, rounding, or fatigue; replacing these components proactively with the 48R499 ensures that your tooling setup remains compliant with safety standards and operates at peak efficiency. It is specifically engineered to interface seamlessly with Walter's proprietary backing pad designs, eliminating the risks associated with ill-fitting generic hardware.

Technical Application and Compatibility

This component is essential for the proper assembly of 3-inch abrasive setups, commonly used for blending, deburring, and finishing in tight spaces. The low-profile head design ensures that the fastener does not interfere with the workpiece, allowing the operator to utilize the full surface area of the abrasive disc without marring the substrate. It is compatible with a range of Walter 3-inch discs, including the popular Flexcut and Topcut series, when used with the appropriate backing pad assembly.

Key Benefits for Industrial Operations

• Safety Compliance: Ensures positive retention of rotating abrasives, reducing the risk of detachment.
• Operational Continuity: Keeping spare screw caps on hand prevents downtime caused by lost or damaged mounting nuts.
• Precision Fit: Designed specifically for Walter mandrels and pads to maintain perfect balance and reduce vibration.
