48S177 - Walter M4x12 Replacement Burnished Screw

Precision OEM Hardware for Walter Tools

The Walter 48S177 Burnished Screw M4X12 is a critical component designed specifically for the maintenance and repair of Walter Surface Technologies' line of industrial power tools. As an Original Equipment Manufacturer (OEM) part, this screw is engineered to meet the exact dimensional tolerances and material specifications required by Walter's high-performance equipment. Using non-OEM hardware in precision tools can often lead to thread stripping, compromised housing integrity, or loosening under the high-vibration conditions typical of grinding and finishing operations. This M4 threaded screw ensures a secure fit that maintains the tool's safety and performance standards.

Technical Specifications and Finish

This fastener features a standard metric M4 thread profile with a 12mm length, a common size utilized in securing protective guards, gear housings, or internal electronic assemblies within Walter tools. The "burnished" finish is a chemical blackening process that converts the surface of the steel into magnetite. This treatment serves multiple engineering purposes: it provides a degree of corrosion resistance without altering the screw's dimensions (unlike plating, which adds thickness), it reduces light reflection which can be beneficial in visual inspection, and it offers mild lubricity to prevent galling during installation. The steel composition is selected to withstand the torque requirements of assembly and the operational stresses of the tool.

Maintenance and Reliability

For industrial MRO (Maintenance, Repair, and Operations) professionals, stocking genuine spare parts like the 48S177 is essential for minimizing downtime. When a tool is disassembled for service—whether for brush replacement, cord repair, or internal cleaning—fasteners can be lost or damaged. Replacing them with the correct Walter specification ensures that the reassembled tool meets factory safety ratings. The burnished finish also matches the aesthetic of the tool's original hardware, maintaining a professional appearance. This screw represents the manufacturer's commitment to quality down to the smallest component, ensuring that every part of the tool contributes to its overall longevity and reliability.
