مفتاح ربط قابل للعكس من ساتا قياس (5/16") موديل (ST46671BU)

The wrench has a small lever on the head that flips to switch the ratcheting direction. Flip the lever to change from tightening to loosening (or vice versa) without removing the wrench from the fastener, saving time in confined areas.

The ratcheting box end needs as little as 5° of movement to advance the fastener, compared to about 30° for a standard box-end wrench. This enables quicker cycles and easier work in tight spots.

The 15° offset provides added knuckle clearance, reducing obstruction when turning fasteners in cramped spaces and improving comfort during extended use.

Surface Drive technology distributes contact across a larger surface area to minimize fastener rounding, helping you maintain the fastener’s shape and achieve better torque transfer.

Size: 5/16". Construction: durable steel. Finish: corrosion-resistant chrome. Features: reversible ratcheting mechanism, 15° offset, compact design, ergonomic non-slip handle.

It's well-suited for automotive work, bicycle repairs, appliance maintenance, and other mechanical assemblies where space is limited and frequent direction changes are needed.

Engage the 5/16" fastener, choose the desired direction with the reversal lever, apply steady torque, and leverage the ratcheting action to advance or loosen with minimal hand movement. Keep the head clean and dry to maintain smooth operation.

Wipe the wrench after use, keep it dry to prevent rust, and apply a light lubricant to the ratcheting mechanism if it begins to feel stiff. Store in a dry place to preserve chrome finish and prevent corrosion.

This wrench is designed for 5/16" fasteners. It’s not suitable for non-hex fasteners or sizes outside 5/16". Use the correct fastener size to avoid rounding and tool damage.

This model emphasizes a compact design with a 5° ratcheting action, a 15° offset for knuckle clearance, and Surface Drive technology for reduced fastener rounding. When comparing, consider size options (e.g., 1/4", 3/8" variants), offset angle, and whether you need the same 5° efficiency with a different fastener size.

Yes. Its ergonomic handle, durable chrome finish, and efficient ratcheting mechanism make it capable for both occasional home projects and more frequent professional tasks, especially in tight spaces.
