48S714 - Walter OEM Replacement Screw 4.2x19 DIN 7981

Genuine Walter Replacement Hardware

The Walter 48S714 is a high-quality replacement screw designed specifically to meet the rigorous standards of Walter Surface Technologies equipment. When maintaining high-performance industrial tools, using genuine Original Equipment Manufacturer (OEM) parts is crucial for ensuring longevity and safety. This specific fastener is manufactured to the DIN 7981 standard, which designates it as a cross-recessed pan head tapping screw. The precision engineering behind this standard ensures that the screw provides optimal clamping force and resistance to backing out, even in high-vibration environments often found in grinding and finishing operations.

With a diameter of 4.2mm and a length of 19mm, this screw is sized for specific assembly points within Walter's machinery lineup. The "Bz" designation in the product name typically refers to the specific finish or material treatment applied to the fastener, ensuring it meets the corrosion resistance and strength requirements necessary for industrial applications. Unlike generic hardware store fasteners, which may have varying tolerances or inferior metal grades, this genuine Walter part guarantees a perfect thread engagement. This is particularly important for self-tapping screws, where the integrity of the mating material depends on the screw's ability to cut or form its own thread without stripping the bore.

Maintenance professionals understand that the smallest components often dictate the reliability of the entire machine. A compromised screw can lead to loose housing, rattling components, or even safety hazards during operation. By choosing the 48S714, you are investing in the continued reliability of your Walter tools. Whether you are performing a routine service, replacing a worn component, or reassembling a tool after a deep clean, this screw provides the assurance of factory-spec performance. Its pan head design offers a low profile with a flat bearing surface, ideal for securing sheet metal covers, plastic guards, or internal brackets securely.

Installation of the 48S714 is straightforward, utilizing a standard cross-recess (Phillips) driver. Users should ensure they use the correct driver size to prevent cam-out and damage to the screw head. As a DIN 7981 tapping screw, it is designed to be driven into a pre-drilled hole, forming its own mating threads in the substrate. This mechanism provides a tight, vibration-resistant fit that is essential for the heavy-duty cycles Walter tools endure. Keep your inventory stocked with these essential spare parts to minimize downtime and maintain the structural integrity of your valuable equipment.
