Flat Combination Spanner NEO tools 16 x 17 mm model 09-816

Flat Combination Spanner NEO tools 16 x 17 mm model 09-816 is a hand tool designed for manual tightening and loosening of nuts and bolts. The spanner has two open ends of different metric sizes, 16 mm and 17 mm, in a compact, single-piece design suitable for use in toolboxes, workshops and on-site repair tasks. The tool is intended for mechanical, automotive and household applications where adjacent metric sizes are commonly encountered.

Advantages

The flat combination spanner features two commonly used metric sizes in one tool, reducing the need to switch between separate wrenches. Its compact, low-profile design improves access in confined spaces and makes it easy to store in a toolbox or carry to a job site. Constructed from hardened metal for durability, the spanner provides reliable torque transfer and a stable fit on hexagonal fasteners.

Suitable for

• Mechanical repairs and assembly work
• Automotive maintenance and minor vehicle repairs
• Household tasks such as furniture assembly and appliance maintenance
• Field service and on-site repair where space and weight are limited

Key specifications

• Two open-end sizes: 16 mm and 17 mm
• Flat, single-piece combination spanner design
• Material: hardened metal alloy for strength and wear resistance
• Compact length suitable for tight spaces and toolbox storage
• Manual operation for tightening and loosening hexagonal nuts and bolts

How to use

Select the end with the correct size for the fastener (16 mm or 17 mm). Position the open end over the nut or bolt head, ensuring full contact on the flats to minimize rounding. Apply steady hand force to turn the fastener in the required direction; use controlled movements to avoid slipping. For stubborn or high-torque fasteners, verify that the spanner size matches the fastener and consider using a different tool rated for higher torque.

Usage recommendations

Inspect the spanner for wear or damage before use and keep contact surfaces clean for optimal grip. Do not use the spanner as a hammer or pry bar. Store the tool in a dry place to prevent corrosion and maintain performance.
