Mounting screw for disc by Dedra XDED7758.39 is a replacement fastener engineered to secure cutting and grinding discs on compatible angle grinders and rotary tools. It restores proper clamping and stable disc positioning to maintain safe operation after the original screw has become worn, damaged, or lost. The component is designed to match the mechanical and dimensional requirements of supported accessories to ensure consistent alignment and torque transfer during use.
Advantages
This mounting screw offers straightforward replacement of worn or missing fastening hardware, helping to quickly return a tool to service. Its design focuses on reliable clamping and minimal play between the disc and arbor, which supports consistent cutting and grinding performance. The part is compact and intended for direct fitment with compatible discs and tool spindles, reducing downtime and avoiding the need for larger repair operations.
Suitable for
- Replacement of a lost or damaged disc mounting screw on angle grinders
- Securing cutting discs for metal, stone, or masonry work when compatible with the tool
- Securing grinding discs for stock removal, surface preparation, or rust removal
- DIY and professional maintenance where original fastening parts are required
When it may not be suitable
This screw may not be suitable if the thread size, diameter, or flange dimensions do not match the specific spindle or disc used; using an incorrect fastener can cause unstable mounting or unsafe operation. It is not a universal solution for all angle grinders — compatibility must be verified before installation.
Key specifications
- Function: fastening/mounting screw for cutting and grinding discs
- Intended use: replacement part for securing discs on compatible rotary power tools
- Material considerations: metal fastener designed for mechanical clamping (material finish may vary)
- Typical compatibility: angle grinders and similar rotary tools that accept this style of screw
How to use
Ensure the tool is powered off and disconnected from power before attempting any replacement. Remove the worn or damaged screw and inspect the spindle and disc for wear or damage. Position the disc correctly on the spindle, align any flanges as required by the tool, and thread the mounting screw by hand to avoid cross-threading. Tighten the screw using the appropriate wrench or tool supplied with the grinder to the manufacturer’s recommended torque or until the disc is securely clamped without overtightening. After installation, perform a brief no-load run of the tool to confirm the disc is stable and runs true.
What to consider before purchase
- Verify thread size, diameter, and flange dimensions match your grinder and disc assembly
- Confirm the screw style is compatible with your disc type (cutting vs grinding) and tool model
- Inspect spindle and disc condition to ensure replacement screw will secure a properly fitting assembly
Usage recommendations
Use this Dedra mounting screw only with discs and tools that match its dimensions and design. Regularly inspect the screw and clamping surfaces for wear or damage, and replace immediately if any deformation, stripping, or looseness is detected to maintain safe operation.
