48S166 - Walter M10 x 1.5 x 8mm Hex Socket Set Screw - Flat Point

Precision Fastening with Genuine Walter OEM Parts

The Walter 48S166 M10 x 1.5 x 8mm Hexagon Socket Set Screw is a critical component designed to maintain the structural integrity and operational precision of Walter Surface Technologies' high-performance power tools. In the realm of industrial maintenance and repair operations (MRO), the use of genuine Original Equipment Manufacturer (OEM) fasteners is paramount. Unlike generic hardware store alternatives, this set screw is manufactured to the exact metallurgical and dimensional specifications required by Walter's engineering standards. This ensures that the tensile strength and hardness of the screw match the demands of the equipment it secures, preventing premature failure under the high torque and vibration conditions typical of metalworking environments.

This specific fastener features a standard M10 metric thread with a coarse 1.5mm pitch, a common configuration in heavy-duty European and North American industrial machinery. The 8mm length is specifically calculated to sit flush or sub-flush within the assembly, eliminating protruding heads that could catch on clothing or interfere with moving parts. The drive mechanism is a precision-broached internal hexagon (hex socket), designed to be driven by a standard Allen key. This drive style allows for the application of significant torque without the risk of cam-out associated with Phillips or slotted drives, ensuring the screw can be tightened securely to hold components like pulleys, gears, or tool holders in place.

The flat point design of this set screw is particularly significant. Unlike cup-point or cone-point screws that bite into the shaft to create a mechanical lock, a flat point screw relies on friction and compressive force against a flat surface or a milled flat on a shaft. This design choice is intentional to prevent marring or damaging the mating component, allowing for frequent disassembly and reassembly without degrading the equipment. Whether you are repairing a Walter magnetic drilling unit, a grinder, or another piece of specialized finishing equipment, utilizing the correct 48S166 screw ensures that your warranty remains valid and your tool operates with the precision for which Walter is known.
