Proto 11 Piece Oxygen Sensor Socket Set JFEOS11-SBD
Details
Proto's JFEOS11-SBD (also identified as model JFEOS11) is a professional-grade 11-piece fractional (SAE) offset box wrench set designed for high-performance mechanical work in tight or obstructed areas. This industrial collection features a 45 degree offset design, providing the necessary clearance for your fingers and allowing access to fasteners that are recessed or blocked by other components. Precision-forged from high-strength alloy steel with a full-polish chrome finish, each wrench utilizes a 12-point configuration and Proto's advanced TorquePlus technology to maximize surface contact and prevent fastener rounding. By integrating the JFEOS11-SBD into your professional toolkit, you gain a versatile, high-torque solution that ensures efficiency and safety in demanding automotive and factory maintenance environments.
Key Features
Comprehensive 11-piece fractional (SAE) set includes wrench sizes: 1/4 x 5/16 inch, 3/8 x 7/16 inch, 1/2 x 9/16 inch, 5/8 x 11/16 inch, 3/4 x 13/16 inch, 7/8 x 15/16 inch, 1 x 1-1/16 inch, 1-1/8 x 1-1/4 inch, 1-5/16 x 1-3/8 inch, 1-7/16 x 1-1/2 inch, and 1-5/8 x 1-3/4 inch.
Total product weight of 18.77 lbs (approximately 8.51 kg) reflects its heavy-duty, industrial-grade construction built for high-leverage professional tasks.
45 degree offset box end provides critical clearance for knuckles and allows the wrench to reach over obstructions to engage recessed fasteners.
12-point box end geometry provides twice as many engagement positions as standard 6-point wrenches, facilitating work in cramped or restricted spaces.
Features the advanced TorquePlus internal design, which uses a radius-corner configuration to shift stress away from fastener corners and distribute it over a larger area.
Precision-forged from high-strength alloy steel to withstand the significant torque requirements of professional mechanical maintenance.
Full-polish chrome finish delivers superior resistance to rust, corrosion, and industrial fluids while ensuring effortless cleanup and a professional appearance.
Supplied in a heavy-duty tool roll for secure organization, protection, and rapid inventory management on the job site.
Designed to allow for effective fastener rotation even at a thirty degree offset in standard mechanical applications.
Manufactured to meet or exceed ASME B107.100 technical standards for professional tool safety and performance.
