48S808 - Walter Replacement Torx Screw T15 St3.9 x 13mm

Genuine OEM Replacement Fastener for Walter Power Tools

The Walter Surface Technologies 48S808 Screw-Torx T15 St3.9 X 13-F is a critical replacement component designed to maintain the structural integrity and operational safety of your premium industrial power tools. As an Original Equipment Manufacturer (OEM) part, this screw is manufactured to the exact metallurgical and dimensional specifications required by Walter's engineering standards. Utilizing non-OEM fasteners in high-vibration equipment like grinders, sanders, and finishing tools can lead to housing misalignment, stripped threads, or compromised safety features. This specific fastener ensures a perfect fit, restoring your equipment to its factory condition.

The screw features a Torx T15 drive head (star drive), which is widely preferred in industrial applications for its ability to transmit high torque without "cam-out." Unlike traditional Phillips or slotted screws, the Torx design allows for secure tightening and easy removal during maintenance intervals, significantly reducing the risk of damaging the fastener head or the surrounding tool housing. This is particularly important for tools that undergo regular service or brush changes.

With a dimension of St3.9 x 13mm, this self-tapping style screw is typically used to secure housing shells, handle assemblies, or internal components where precise thread engagement is necessary to resist the harmonic vibrations generated by high-RPM motors. The "F" designation often indicates a specific thread pitch or finish designed to bite securely into the mating material—whether reinforced polymer or metal—without causing stress fractures. Maintaining a stock of these specific screws is essential for tool crib managers and maintenance personnel responsible for the upkeep of Walter's extensive line of surface finishing equipment.

Investing in genuine Walter parts like the 48S808 guarantees that your warranty remains valid and your tools continue to perform at the high level expected from the brand. Whether you are repairing a Line-Mate, a Big Buff, or another tool in the Walter lineup, verify your parts diagram to ensure this specific SKU is the correct match for your assembly.
