48S161 - Walter Replacement Screw M4 x 20mm

Keep Your Equipment Secure with the Walter M4X20 Screw

In the demanding environment of a welding shop or industrial fabrication floor, your power tools are your lifeline. Walter Surface Technologies is known for building robust, high-quality equipment designed to withstand heavy use. However, even the toughest tools require maintenance. Whether due to vibration loosening fasteners over time or accidental loss during a repair, missing screws can sideline an important piece of equipment. The Walter 48S161 Screw M4X20 is the authentic replacement part you need to get your gear back in action quickly and safely.

Why Choose Genuine Walter Parts?
While it might be tempting to grab a generic screw from the bin, using non-OEM hardware on high-performance tools can lead to headaches down the road. Generic screws may not have the same grade of steel, corrosion resistance, or precise dimensional tolerance as the original. The 48S161 is manufactured to Walter's exact specifications. This means the M4 threads will engage perfectly without binding, and the 20mm length is exactly right for the intended application—ensuring that safety guards stay put and housings remain sealed against dust and debris.

Application and Maintenance
This M4x20 screw is a versatile component likely found in various Walter power tools, such as angle grinders, line finishers, or magnetic drills. It is often used to secure outer shells, handle assemblies, or protective covers. Regular tool maintenance is key to safety in the workplace. We recommend checking your tools weekly for loose or missing hardware. If you spot a missing screw, replacing it with the 48S161 restores the tool to its factory safety rating. A loose housing can lead to excessive vibration, which not only causes operator fatigue but can also damage the tool's internal motor and bearings.

Ready for the Job
Don't let a missing 20mm screw stop production. Keeping a few of these 48S161 screws in your maintenance crib ensures that minor repairs can be handled immediately, minimizing downtime. This part represents the quality and reliability you expect from the Walter brand, ensuring that every connection on your equipment is secure and ready for the toughest grinding, cutting, or finishing tasks.
