5x8x9.5mm Nickel-Plated Eccentric Column Roller Nut for V-Slot

The 5x8x9.5mm nickel-plated eccentric roller nut is a high-precision mechanical fastener designed for fine-tuning linear motion systems on V-slot aluminum profiles. This eccentric nut features an offset 5mm inner hole, allowing it to fit standard M5 bolts used in 3D printer gantry plates and wheel assemblies. By rotating the 8mm hexagonal body, users can adjust the distance between the guide wheels and the aluminum rail to eliminate wobbling and ensure a perfectly smooth glide. Manufactured from high-strength steel with a premium nickel-plated finish, this nut provides excellent wear resistance and protection against corrosion. The 9.5mm height is a specific standard required for many specialized carriage designs, providing the necessary vertical offset for optimal wheel alignment and tensioning in DIY CNC and 3D printing projects.

Features:

• Precision Eccentric Adjustment: Offset bore allows for micrometer-level adjustment of wheel tension against linear profiles.
• Durable Nickel Plating: Offers a smooth, corrosion-resistant surface for long-term mechanical reliability.
• 8mm Hexagonal Profile: Compact 8mm hex body allows for easy adjustment using standard small-format wrenches.
• High-Strength Steel Construction: Engineered to maintain precise positioning under constant mechanical stress and vibration.
• Universal M5 Compatibility: Features a 5mm inner diameter optimized for M5 screws commonly used in V-slot systems.
• Compact 9.5mm Height: Specifically designed for low-profile carriage plates and space-constrained motion assemblies.

Package Includes:

1 x Nickel-plated eccentric roller nut, 5mm inner hole, 5*8*9.5
