SATA ST47505ST Double Flex Head Socket Wrench 16 x 17mm

Both ends are flexible, allowing you to angle the wrench to awkward or confined spaces. The socket end can pivot up to 180° to access fasteners that are hard to reach, improving leverage and reducing strain.

The 12-point (12pt) socket end engages fasteners more easily from slight angles and the 180° pivot lets you reposition quickly without removing the wrench, saving time in tight spots.

Off-corner loading concentrates grip on the sides of the fastener rather than the corners, reducing rounding and wear on fasteners while improving torque transmission.

The wrench features high-visibility stamped markings on each end, clearly indicating 16mm on one end and 17mm on the other for fast size recognition.

It’s crafted from high-strength steel and finished with a corrosion-resistant coating to withstand heavy use and resist rust over time.

It’s built for high-torque applications and is well-suited for automotive work, mechanical maintenance, and general home-improvement tasks where both sizes and flexible access matter.

SATA ST47505ST provides two sizes in one 16 x 17mm configuration with a double flex head and 180° socket pivot for better reach in tight spots, whereas SATA ST47504ST offers a 14x15mm sizing with a different end configuration. If you frequently deal with both 16/17mm and 14/15mm fasteners, ST47505ST adds versatility.

ST47505ST covers 16mm and 17mm bolts with a compact, flexible design, ideal for tighter spaces. ST47506ST targets larger fasteners (18x19mm) with a similar flex design but for bigger applications. If you work with a range of bolt sizes, both offer flexibility but in different size scopes. Compare here: https://fepy.com/product/sata-st47506st-double-flex-head-socket-wrench-18x19mm

Use it for automotive fasteners in confined engine bays, motorcycle maintenance, bike repairs, appliance servicing, and any project requiring reach and access to 16mm or 17mm bolts in tight spaces.

Identify which end fits the fastener, use the appropriate end (16mm or 17mm), and leverage the 180° pivot to position the socket for a comfortable angle. Engage the fastener with steady torque, keeping the wrench perpendicular to the fastener to avoid slippage.

Wipe clean after use to remove grease and debris, dry it completely, occasionally apply a light anti-corrosion oil to the pivot area, and inspect for any play or wear in the flex head. Store in a dry place to prevent rust.

Yes, if you frequently encounter hard-to-reach fasteners, the dual-size ends plus the 180° pivot and off-corner loading design provide versatility and durability for automotive, mechanical, and home tasks, making it a strong value option among similar double-head wrenches on Fepy.

Wear eye protection if working near debris, ensure the correct end size is seated fully on the fastener before applying torque, avoid over-torquing to prevent slip or bolt head rounding, and keep hands clear of the pivot area when snapping the head to a new position.
