King Tony 19001617 open end wrench

King Tony 16x17 mm flat wrench model KT19001617 is a double-ended hand tool with two fixed open jaws in 16 mm and 17 mm sizes. Manufactured from hardened steel and finished for corrosion resistance, this compact flat wrench is intended for turning hexagonal nuts and bolts in mechanical, automotive and general maintenance tasks. The slim profile and solid construction provide access in confined spaces and reliable torque transfer for workshop, garage and field servicing.

Advantages

The flat double-ended design combines two common sizes in one tool, reducing the number of individual wrenches required for routine work. Hardened steel construction increases durability and wear resistance while the precisely formed jaws ensure a secure fit on hex fasteners to minimise rounding. The slim, low-profile head gives better access to tight or recessed nuts and bolts and the single-piece construction improves strength and longevity under repeated use.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Workshop and garage hand tools set
• On-site service and field maintenance
• Plumbing and light industrial fastening tasks

Key specifications

• Sizes: 16 mm and 17 mm open ends
• Type: flat double-ended open wrench
• Material: hardened steel with protective finish
• Profile: low-profile head for confined spaces
• Construction: single-piece forged design for strength

How to use

Select the end with the matching size for the nut or bolt. Position the open jaw fully onto the hexagonal fastener so the contact surfaces sit squarely against the flats of the nut or bolt. Apply steady force to turn the wrench; use slow, controlled movements to avoid slipping and rounding the fastener. If additional leverage is required, choose a longer wrench rather than applying excessive force to the King Tony 16x17 mm flat wrench to prevent damage to the tool or fastener.

Usage recommendations

Keep the wrench clean and apply light corrosion protection after use when exposed to moisture. Use the correctly sized end to reduce fastener damage and inspect the jaws periodically for wear; replace the tool if jaws show significant deformation or rounding.
