48S247 - Walter M4x8 Countersunk Replacement Screw

Precision OEM Hardware for Walter Industrial Tools

The Walter 48S247 Screw M4X8 Csk Hd is a specialized replacement fastener designed to meet the rigorous engineering standards of Walter Surface Technologies' power tool line. In the realm of industrial maintenance, repair, and operations (MRO), the integrity of every component—down to the smallest fastener—is critical for the safe and efficient operation of high-speed equipment. This screw features a metric M4 thread profile with a standard coarse pitch, ensuring compatibility with the tapped holes found in specific Walter tool housings, guards, and internal assemblies.

The "Csk Hd" designation indicates a Countersunk Head design. This geometric feature is essential for applications where the fastener head must sit flush with or below the surface of the mating part. In power tools like angle grinders, line finishers, and sanders, flush-mounted screws are vital to prevent snagging on workpieces, interference with moving parts, or discomfort for the operator. The 8mm length is precisely calculated to engage sufficient thread depth for maximum holding power without protruding into internal cavities where it could contact armatures or gears.

Utilizing genuine OEM parts like the 48S247 ensures that the material properties of the fastener match the requirements of the tool. Generic screws may lack the tensile strength or shear resistance necessary to withstand the high-frequency vibrations inherent in abrasive finishing operations. Over time, inferior hardware can loosen or shear, leading to safety hazards or catastrophic tool failure. This screw is manufactured from high-grade steel, offering the necessary hardness to resist stripping during installation and the durability to endure the thermal and mechanical stresses of industrial use.

Maintenance professionals and tool crib managers should maintain a stock of these specific fasteners to minimize downtime. When servicing Walter equipment, replacing worn or damaged screws with the correct 48S247 part guarantees that the tool is returned to its original factory specifications. Whether securing a protective guard, a handle assembly, or an internal bracket, this M4x8 countersunk screw provides the reliability expected from the Walter brand.
