OTC 3-3/4" 6-point wheel bearing locknut socket vs AFF 3/4" Drive Wheel Bearing Locknut Socket (6 or 8 points)
Overall winner: OTC 3-3/4" 6-point wheel bearing locknut socket
Key Differences
OTC (A) is a purpose-built 3-3/4" 6-point socket rated for manual 3/4" square-drive use and emphasizes resistance to rounding under high torque; AFF (B) offers both 6- and 8-point options and laser-etched sizes for identification but notes possible sizing/fit issues. Choose OTC if you want a higher-rated, manual-drive-specific 6-point tool and greater durability assurances; choose AFF if you need the flexibility of 6- or 8-point engagement and easier size ID
