48S173 - Walter M5x20 Socket Head Cap Screw DIN 912

Keep Your Equipment Running with the Walter 48S173 Replacement Screw

In the world of professional welding and metal fabrication, equipment downtime is the enemy of productivity. Often, it is the smallest components that cause the biggest headaches. A stripped, lost, or broken screw can render a high-value piece of machinery useless until a replacement is found. The Walter 48S173 is a genuine replacement M5x20 Socket Head Cap Screw, designed specifically to get your Walter tools and equipment back in action. Whether you are repairing a magnetic drill, a grinder, or a finishing system, using the correct fastener is the first step in a successful repair.

This screw follows the DIN 912 standard, which means it has a tall, cylindrical head with a hexagonal socket drive. This design is a favorite among mechanics and fabricators because it is easy to install in tight, recessed spaces where a standard wrench simply won't fit. You will need a standard metric Allen key (hex key) to drive this screw. The M5 thread size is a common metric standard, but the specific 20mm length is critical for the intended application. Using a screw that is too short may result in stripped threads due to insufficient engagement, while a screw that is too long might damage internal components or fail to tighten the assembly down completely.

Why choose a genuine Walter part over a generic hardware store screw? Quality and peace of mind. Walter Surface Technologies builds equipment to withstand the harsh environments of metalworking shops—dust, heat, and vibration are constant factors. The fasteners holding their machines together are chosen for their tensile strength and durability. By using the authentic 48S173, you ensure that the replacement part matches the original specifications exactly. This prevents issues like galvanic corrosion from mismatched metals or fitment issues caused by poor manufacturing tolerances found in cheap bulk hardware.

We recommend keeping a few of these essential spare parts in your maintenance kit. When you are in the middle of a job and need to perform field maintenance on your Walter tools, having the right screw on hand saves you a trip to the supply house and keeps your fabrication line moving. Trust in the reliability of OEM parts to maintain the safety and performance of your valuable tools.
