How to use

Insert the blade into a compatible System 4 holder until it seats securely according to the holder's retention method. Select the correct TORX size to match the fastener and apply steady axial pressure while turning to engage the tip fully. For access to recessed screws, use the 120 mm length to reach into confined spaces while maintaining control. Replace worn or damaged blades promptly to maintain torque accuracy and reduce the risk of fastener damage.

Recommendations

Regularly inspect the TORX tip for rounding or wear and replace the blade when fit becomes loose or slipping occurs. Use the blade with System 4-compatible holders rated for hand torque only; avoid using the blade with impact drivers unless explicitly specified by the tool system. Store blades in a protective holder or rack to prevent tip damage and to maintain precise TORX engagement.
