48S715 - Walter 4.2x9.5mm Pan Head Tapping Screw (DIN 7981)

Genuine Walter Replacement Hardware

The Walter 48S715 Screw Bz 4.2X9.5 Din 7981 is a critical component for the maintenance and repair of Walter Surface Technologies power tools and industrial equipment. As a genuine Original Equipment Manufacturer (OEM) part, this screw is engineered to the exact specifications required to keep your machinery operating safely and efficiently. Utilizing non-standard or generic fasteners in precision tools can often lead to compromised housing integrity, stripped threads, or vibration issues. By choosing this authentic Walter replacement part, you ensure that your equipment remains compliant with its original design parameters.

Technical Precision and Standards

This fastener is manufactured according to the DIN 7981 standard, which specifies the requirements for cross-recessed pan head tapping screws. The dimensions are strictly controlled, featuring a 4.2mm diameter and a 9.5mm length. The "Bz" designation typically refers to the specific finish or material treatment selected by Walter to resist corrosion and wear within the operating environment of their tools. The pan head design offers a flat bearing surface, which is essential for distributing clamping force over a wider area, thereby reducing the risk of crushing or cracking the material being fastened—a common issue when repairing plastic or composite tool housings.

Importance of OEM Maintenance

Regular maintenance of industrial power tools extends their lifecycle and protects the user. Small components like the 48S715 screw play a vital role in holding protective guards, handles, and internal components in place. A missing or loose screw can lead to misalignment of internal parts, increased vibration, and potential safety hazards. This replacement screw is designed to bite securely into the mating material, providing a hold that resists the high-frequency vibrations often generated by grinding and finishing applications. Whether you are a certified repair technician or performing in-house maintenance, relying on the correct part number ensures a hassle-free repair process.

Application and Compatibility

While specifically cataloged as a spare part for Walter equipment, the DIN 7981 standard is widely recognized. However, users should verify the specific part number 48S715 against their tool's exploded view diagram or parts list to guarantee compatibility. This screw is typically used in the assembly of tool bodies, switch covers, or accessory mounts. Investing in the correct hardware prevents the frustration of mismatched threads and ensures your premium Walter tools continue to deliver the performance you expect.
