Chave de caixa KS Tools 913.3917 encaixe 3/8" 12 pontas 17 mm

KS Tools socket wrench 913.3917 is a 17 mm, 12-point socket designed for use with a 3/8" drive ratchet. The tool provides secure engagement with hexagonal and double-hex fasteners, enabling precise torque transfer during tightening and loosening operations. Its compact length and 12-point profile make it suitable for confined spaces and repeated workshop use in automotive repair, machinery maintenance and general assembly tasks.

Advantages

The 12-point geometry allows quick alignment with the fastener and multiple engagement angles, reducing the need for repositioning in tight spots. Machined internal faces ensure a snug fit on 17 mm heads, minimizing rounding and slippage. Constructed from tool-grade chrome vanadium steel with a corrosion-resistant finish, the socket balances strength and durability while remaining compatible with standard 3/8" drive ratchets and extensions.

Suitable for

• Automotive repair and maintenance — wheel, engine and chassis fasteners
• Mechanical assembly and disassembly tasks
• Workshop and garage use with 3/8" drive ratchets
• Maintenance of machinery and equipment with 17 mm fasteners

Key specifications

• Size: 17 mm
• Point type: 12-point (double-hex) profile
• Drive: 3/8" drive compatibility
• Material: chrome vanadium steel (tool-grade)
• Finish: corrosion-resistant plating
• Typical length: compact design for confined access

How to use

Select a compatible 3/8" drive ratchet or extension and attach the socket by pressing it onto the ratchet square drive until it locks. Position the socket over the 17 mm fastener, ensuring full seating of the 12-point profile. Apply steady torque in the required direction to tighten or loosen the fastener. For best results in confined or obstructed areas, use a short extension or universal joint as needed and avoid excessive impact or side-loading that could damage fastener heads or the socket.

Recommendations

Inspect the socket and fastener before use; replace the socket if signs of wear, cracking, or rounded internal faces appear. Use with a torque-limited wrench when specific torque values are required. Store in a dry toolbox to preserve the corrosion-resistant finish.
