Box-end wrenches set by Topex, model TOP-35D856 — 8 pieces, sizes 6–22 mm

Set of 8 Topex box-end wrenches model TOP-35D856 includes sizes 6, 7, 8, 9, 10, 11, 13, and 22 mm and is designed to deliver a secure grip on hex fasteners. Each tool features a closed-loop end that surrounds the nut or bolt head to reduce rounding and provide even force distribution. The compact range of metric sizes makes this set suitable for tasks where space is restricted and a firm, reliable connection between tool and fastener is important.

Advantages

The Topex box-end wrenches set offers consistent contact with fasteners, minimizing slippage and damage to bolt heads. Their closed-loop design provides improved torque transfer compared with open-end alternatives, while the compact layout of sizes allows users to carry a useful selection without excess weight. The set is intended for general mechanical use and is compatible with a variety of materials and fastener conditions encountered in routine maintenance and repair work.

Suitable for

• Automotive repairs: access to engine and chassis nuts and bolts.
• Bicycle maintenance: tightening and loosening axle and component fasteners.
• Household repairs: furniture assembly, appliance maintenance and plumbing fittings.
• Workshop tasks: general bolt and nut work in confined spaces.

Key specifications

• Number of pieces: 8
• Size range: 6 mm to 22 mm (individual sizes: 6, 7, 8, 9, 10, 11, 13, 22)
• End type: closed-loop (box) on each side
• Measurement system: metric
• Intended use: manual tightening and loosening of hex fasteners

How to use

Select the wrench size that corresponds to the fastener head, place the closed-loop end fully over the nut or bolt, and apply steady force in the required direction. When working in confined spaces, position the wrench so the loop fully engages the fastener to avoid slipping; if additional leverage is required, use controlled, steady pressure rather than sudden force. Inspect fasteners for wear or damage before applying torque, and choose the correct size to maintain tool and fastener condition.

Usage recommendations

For safe and effective use, keep the wrenches clean and free of oil or debris that could reduce grip. Store the set in a dry place to prevent corrosion. Use the correct size to prevent rounding fastener corners and avoid using the tool as a hammer or pry bar. For high-torque applications, consider using a calibrated torque wrench to achieve specified torque values rather than exceeding manual limits.
