Sk 45963 Ball End Hex Bit Socket 3/8 in Drive 3 Mm

Product Description

The SK 45963 is a long ball end hex bit socket designed for driving 3 mm hex fasteners in confined or angled workspaces. Built with a 3/8 inch drive, it accepts standard 3/8 inch drive ratchets and extension bars. The socket measures 6 inches overall length with a 5 inch bit length, giving techs the reach needed for deep fastener access. The ball end geometry allows engagement at off-axis angles, which is useful when working around obstructions in mechanical assemblies. Finished in chrome over a steel body, it is suited for professional hand-tool use across HVAC, plumbing, and general mechanical service applications.

This socket is commonly used by HVAC technicians, plumbers, and electricians who encounter hex fasteners on equipment panels, motor mounts, valve assemblies, and control enclosures. The long overall length makes it practical for reaching fasteners recessed in equipment cabinets or behind structural components. The ball end allows the socket to seat on the fastener at angles that a standard hex bit cannot, reducing the need to reposition the tool during service calls.

Key Features

• Ball end tip allows fastener engagement at off-axis angles
• 3/8 inch drive fits standard ratchets and extensions
• 3 mm hex size for metric fastener applications
• 6 inch overall length with 5 inch bit length for deep reach
• Steel construction with chrome finish for durability and corrosion resistance
• Long ball end design reduces tool repositioning in tight spaces

Compatibility

Designed as an OEM-style hand tool socket for use with standard 3/8 inch drive ratchets, torque wrenches, and extension bars requiring a 3 mm long ball end hex bit.

Installation Notes

This socket is installed and removed by hand using a compatible 3/8 inch drive ratchet or torque wrench. Ensure the drive tool is rated for the torque required by the fastener application. Inspect the socket for wear or rounding before each use and replace if the hex tip shows deformation. Do not use impact drivers with this hand socket unless the tool is rated for impact use.
