48S251 - Walter Replacement Tapping Screw St2.9 x 12mm

Genuine Walter Replacement Hardware

The Walter Tapping Screw St2.9X12 (SKU: 48S251) is a specialized replacement fastener designed specifically for Walter Surface Technologies equipment. In the realm of industrial maintenance and repair operations (MRO), the integrity of every component—down to the smallest screw—is critical for the safe and efficient operation of power tools and finishing systems. This tapping screw features a metric St2.9 thread profile with a 12mm length, engineered to precise tolerances to ensure a secure hold within the machine's assembly.

Using genuine OEM parts like the 48S251 is essential for maintaining the warranty and performance standards of your Walter tools. Unlike generic fasteners found in hardware stores, this screw is manufactured from high-grade materials selected to withstand the specific vibration frequencies, thermal cycles, and mechanical stresses associated with Walter's high-performance grinding, cutting, and cleaning machines. The self-tapping nature of the screw allows it to cut its own mating threads into the substrate material, providing a tight, gap-free fit that resists loosening over time.

Proper maintenance of industrial equipment often requires the disassembly of housing units for cleaning, brush replacement, or internal repairs. During these procedures, small fasteners can be lost, stripped, or damaged. Replacing them with the exact manufacturer-specified part ensures that the housing remains sealed against dust and debris, and that internal components remain perfectly aligned. This screw is typically used in the assembly of handle casings, protective guards, or electronic control covers on Walter power tools.

For facility managers and repair technicians, stocking OEM spares like the 48S251 reduces downtime. Attempting to force an incorrect thread pitch or length into a tool can damage the housing, leading to more expensive repairs or the need for complete tool replacement. Trust in Walter's engineering to keep your surface finishing workflows running smoothly.
