Industrial Grade Maintenance Solutions

The Walter Tapping Screw St4.8X75 (48S258) is an essential maintenance component for professionals relying on Walter Surface Technologies equipment. In the world of industrial MRO (Maintenance, Repair, and Operations), downtime is costly. Having the right replacement parts on hand, such as this specific tapping screw, ensures that minor repairs do not turn into major production delays. This screw is manufactured to the exacting standards of Walter, a leader in surface treatment technologies and power tools.

Technical Specifications and Fitment

This fastener features a St4.8 diameter and a 75mm length, a specific configuration often found in the assembly of ergonomic handles, motor housings, or gear covers on heavy-duty tools. The "St" designation typically refers to a self-tapping thread designed for thermoplastics or thin metal sheets, providing a vibration-resistant lock that is crucial for handheld power tools. The extended 75mm shank allows it to bridge multiple layers of assembly, securing the tool's internal components against the external shell.

Durability and Reliability

Constructed from durable, industrial-grade metal, this screw resists the mechanical stresses associated with high-torque applications. It is treated to resist corrosion, making it suitable for tools used in harsh environments where moisture or chemicals might be present. Using genuine Walter parts like the 48S258 guarantees that the tensile strength and shear resistance of the fastener match the engineering requirements of the tool, preventing catastrophic failure during operation.

Application in Tool Repair

Whether you are rebuilding a magnetic drilling unit or servicing a large angle grinder, the integrity of every screw matters. A loose or improper screw can lead to housing misalignment, increased vibration, and operator fatigue. This replacement screw provides the confidence that your repair will hold up under pressure. It is an direct replacement part, meaning no modification is needed for installation—simply remove the damaged or missing fastener and replace it with this OEM unit to restore full functionality.
