48S256 - Walter OEM Replacement Tapping Screw St4.2x25

Genuine Walter Replacement Hardware

The Walter Tapping Screw St4.2X25 (SKU: 48S256) is a critical OEM component designed specifically for the maintenance and repair of Walter Surface Technologies power tools and industrial equipment. When servicing high-performance tools, using genuine manufacturer parts is essential to ensure the longevity and safety of the device. This tapping screw features a precise St4.2 metric thread profile and a length of 25mm, engineered to fit exact tolerances within Walter tool housings and assemblies.

Precision Engineering and Fitment

Unlike generic fasteners that may have slight deviations in thread pitch or diameter, this genuine Walter screw is manufactured to strict quality standards. The St4.2 designation indicates a specific thread diameter that is commonly used in robust plastic and metal assemblies found in industrial grinders, sanders, and finishing tools. The 25mm length is calculated to provide optimal thread engagement without bottoming out or protruding, ensuring a secure hold that resists loosening due to the high vibration often associated with power tool operation.

Durability and Material Quality

Industrial environments demand hardware that can withstand stress. This tapping screw is crafted from high-grade steel, offering excellent tensile strength and resistance to shearing forces. The self-tapping nature of the screw allows it to cut its own threads into the mating material or securely follow existing threads, providing a tight, vibration-resistant bond. The surface is treated to resist corrosion, which is particularly important for tools used in metalworking environments where exposure to moisture, coolants, and metallic dust is common.

Maintenance and Repair Applications

Regular maintenance of your Walter equipment often involves disassembling casings to replace brushes, cords, or internal components. During these procedures, screws can become stripped, lost, or damaged. Having the correct replacement part, such as the 48S256, ensures that reassembly restores the tool to its factory specifications. Using incorrect screws can lead to cracked housings, compromised seals, or internal damage, ultimately shortening the life of your valuable equipment. Trust in genuine Walter parts for all your repair needs.
