Proto 1/2" Drive Socket 27 MM - 6 Point J5427MH-SBD

Proto's J5427MH-SBD is a professional-grade 1/2-inch drive 27mm 6-point metric standard socket designed for high-torque industrial and aerospace applications. This socket utilizes the patented TorquePlus™ drive system, which allows for greater force by contacting the flats of the fastener rather than the corners, effectively preventing rounding and damage to hardware. Forged from high-alloy steel and finished in a full polish chrome, it is engineered to provide superior durability and corrosion resistance for demanding professional environments.
Key Features
Standard Length Profile: Features a compact 1-41/64 inch (41.7 mm) overall length, providing an ideal solution for reaching 27mm fasteners in tight or confined workspaces.
TorquePlus™ Drive System: High-performance internal geometry distributes stress over a larger area to protect fasteners and allow for higher torque engagement on worn or rusted bolts.
6-Point Hex Opening: Provides maximum surface contact on 27mm fasteners, ensuring a secure, non-slip grip that is superior to 12-point designs for heavy-duty tasks.
Industrial Strength Alloy Steel: Precision-forged and heat-treated for maximum strength and resistance to metal fatigue, meeting or exceeding ASME B107.110 and AS4984A standards.
Full Polish Chrome Finish: Delivers a professional, easy-to-clean surface that provides exceptional corrosion resistance suitable for harsh industrial conditions.
Optimized Dimensions: Features a 1-3/8 inch (35 mm) drive end width and a 1-1/64 inch (25.8 mm) bolt clearance depth for efficient operation on standard metric hardware.
Product Weight: Weighs approximately 0.37 lbs, providing a robust and balanced feel for high-cycle professional maintenance.
