Metric Socket Set Screws, Cone Point, Hex 4MM Drive, Stainless Steel A2 (18-8), M8 x 1.25 x 30MM
Screw Diameter x Thread Pitch: M8-1.25
|
Metric Cone Point Socket Set Screws in A2 (18-8) Stainless Steel feature a sharp, hardened conical tip that provides the highest holding power of any set screw point style. The cone point is designed to seat into a pre-drilled mating indentation in the shaft or, in softer materials, pierce directly into the workpiece surface—creating a permanent mechanical interlock that resists rotation and axial movement under even extreme loads. This aggressive grip makes cone point set screws the preferred choice for permanent installations, high-torque applications, and assemblies where loosening or slippage cannot be tolerated. The sharp point also provides self-centering action, ensuring precise alignment when engaging a mating detent. The internal hex socket drive allows flush installation below the component surface and enables high torque application without cam-out. Manufactured from A2 (18-8) stainless steel—the most widely used stainless grade for fasteners—these set screws offer excellent corrosion resistance for food processing, marine, outdoor, chemical exposure, and washdown environments. The M8 x 1.25mm coarse thread pitch is a robust metric size commonly used in heavy-duty machinery, agricultural equipment, automotive assemblies, industrial shafting, and applications requiring higher clamping force for permanent component locking.
