48S217 - Walter M8x8 Replacement Set Screw

Precision Fastening with the Walter 48S217 Grub Screw

The Walter 48S217 Grub Screw M8X8 is a critical component designed for precision maintenance and repair of industrial machinery and Walter power tools. As a headless fastener, this grub screw—also commonly referred to as a set screw—is engineered to secure an object within or against another object, typically without the use of a nut. The M8 metric thread profile is machined to exact tolerances, ensuring seamless integration with matching female threads in gear housings, shaft collars, and pulley systems. Its 8mm length is specifically calibrated to sit flush or below the surface of the host component, maintaining the streamlined profile of the equipment and preventing snagging hazards during operation.

Manufactured from high-grade steel, this component exhibits excellent tensile strength and hardness, which are essential properties for resisting the shear forces often applied to set screws in dynamic environments. The internal hex drive (Allen style) allows technicians to apply significant torque to the screw, ensuring it bites firmly into the shaft or mating surface to prevent relative motion. This is particularly important in high-vibration applications where inferior fasteners might back out or loosen over time. For maintenance professionals and tool repair specialists, using genuine OEM parts like the 48S217 ensures that the metallurgical properties and dimensional accuracy match the original specifications of the device, thereby preserving the equipment's warranty and operational safety standards.

In industrial settings, the reliability of small fasteners can dictate the uptime of larger systems. The Walter M8X8 grub screw is treated to resist corrosion and wear, extending the service life of the repair. Whether used for locking a pulley to a motor shaft or adjusting the tension in a mechanical assembly, this part delivers the performance expected from Walter Surface Technologies. It is recommended to install this screw using a calibrated torque wrench and the appropriate hex key to avoid stripping the drive head or damaging the mating threads.
