Why this one
Dual 1/4 inch hex drive ends
This tool features a 1/4 inch hex drive on each end, giving you the same drive size at both sides.
Flexible heads for tight access
Both ends of this wrench incorporate a flex joint that lets you angle the drive into spaces a straight-shaft driver cannot reach.
Chrome vanadium construction
Built from chrome vanadium steel, this tool delivers the strength and durability professional tradesmen demand day in and day out.
Chrome finish for durability
A chrome finish protects the entire wrench against corrosion and makes cleanup fast at the end of the day.
Compact and lightweight
At 196 mm (approximately 7.7 inches) long and weighing just 110 g (about 3.9 oz), this wrench fits easily into a tool roll, pouch, or back pocket.
Read the full description
When a fastener sits deep inside a panel, behind a hose bundle, or tucked under a bracket, a rigid hex driver simply cannot reach it. This Teng Tools wrench solves that problem with a flexible joint at each end, letting you angle the 1/4 inch hex drive to meet the fastener head wherever it hides.
Both ends carry the same 1/4 inch hex drive, so there is no wrong end to grab. Flip the tool around and keep working — no fumbling through a pouch for the right size. The chrome vanadium build handles the torque demands of professional automotive, HVAC, and industrial maintenance tasks, while the chrome surface shrugs off oil, coolant, and shop solvents.
Overall length is 196 mm (approximately 7.7 inches) and weight is just 110 g (about 3.9 oz), making this one of the most compact ways to deliver hex drive capability into confined areas. Slide it into a shirt pocket, clip it to a belt pouch, or toss it in the glove box for roadside repairs.
Whether you are an automotive technician chasing a quarter-inch hex bolt behind an intake manifold, an appliance repair tech reaching behind a control board, or a hobbyist assembling furniture in a tight corner, this tool earns its place in your kit by going where other drivers cannot.
