Always clean T-slots and jaw teeth thoroughly before mounting. Insert the T-nut with the step facing down into the chuck slot, ensuring it does not protrude beyond the chuck OD (risk of flying out at high speed). Tighten the mounting screws with a torque wrench to the recommended value (e.g., 80N·m for M12). Lubricate sliding surfaces regularly with high-temperature grease. For first-time setup, use a dial indicator to check jaw parallelism and concentricity.Package contents: 3 x T-nuts, 6 x mounting screws (matched to size). Mounting wrench not included.

• 【High-Precision 0.01mm Fit for Repeatable Clamping Accuracy】: These hydraulic chuck soft jaw T-nuts are precision-milled and ground to achieve 0.01mm centering accuracy. The tight tolerance ensures consistent transmission of hydraulic piston thrust to the soft jaws, eliminating play and maintaining repeatable positioning across thousands of cycles. Ideal for automated production where clamping consistency is critical.
• 【Quenched and Tempered Medium Carbon Steel (HRC38-45) for Durability】: Manufactured from 40Cr medium carbon steel, then quenched and tempered to HRC38-45. The hardened surface resists wear and deformation under high clamping forces, while the black oxide finish provides resistance. This ensures long service life even in heavy-duty, high-cycle machining environments.
• 【Complete Set with 6 Mounting Screws for Each Size】: Each set includes three T-nuts and six matching mounting screws (M8/M10/M12/M14/M16/M20 depending on chuck size). No need to source separate hardware. The screws are grade-matched for proper torque application, simplifying installation and ensuring secure locking of soft jaws to the T-nuts.
• 【Optimized Dimensions for 5 to 15 Inch Hollow/Solid Hydraulic Chucks】: Available for 5,6,8,10,12,15 inch chucks in both hollow Or solid versions. Detailed parameters – length, bottom width, height, slot width, step height, center distance – are precisely engineered to fit original chuck T-slots. This ensures smooth sliding, proper jaw stroke, and prevents over-travel or interference.
• 【High-Speed Stability and Easy Installation for Automated Cells】: The T-nuts are precision-ground to minimize vibration at high spindle speeds (up to 5000+ RPM). Proper installation with a torque wrench (e.g., M12 @ 80N·m) and regular lubrication of T-slots ensures stable clamping. Ideal for CNC lathes, turning centers, and automated work cells where quick jaw changes and reliable grip are essential.
