Wrench STAHLWILLE 13 — 8 mm, chrome alloy steel, chrome finish, 115×18×7 mm

Single-piece STAHLWILLE 13 open-end wrench, size 8 mm, made from chrome alloy steel with a chrome finish. With overall dimensions of 115×18×7 mm, this compact open-end wrench is designed for tightening and loosening small fasteners in mechanical, automotive and maintenance tasks. The chrome finish provides corrosion resistance suitable for workshop and field use. The tool follows STAHLWILLE design principles that reinforce high-load areas and reduce material where stress is lower, producing a sturdy yet slim and lightweight spanner.

Advantages

The forged construction and optimized material distribution increase resistance to breakage while keeping the wrench slim for access in confined spaces. The chrome alloy steel and chrome surface finish provide durability and corrosion resistance for regular use. The wrench's profile reduces bending under load and delivers a snug, skin-friendly surface finish for comfortable handling. The open-end geometry is shaped to reduce the risk of slippage when applying torque to small nuts and bolts.

Suitable for

• Mechanical assembly and disassembly of small fasteners
• Automotive repairs where space is limited
• Maintenance work in workshops and on-site service jobs
• Precision tightening tasks on machinery and equipment

Key specifications

• Tool type: single-piece open-end wrench
• Nominal size: 8 mm
• Material: chrome alloy steel
• Finish: chrome plated for corrosion resistance
• Overall dimensions: 115 mm length × 18 mm width × 7 mm height
• Profile: slim, optimized material distribution for strength and reduced bending

How to use

Select the 8 mm open end to match the nut or bolt head. Position the wrench squarely on the fastener so the load is applied across the jaw and shaft as evenly as possible. Apply steady torque, avoiding sudden impacts; if higher torque is required, use the appropriate larger tool or leverage method recommended for the fastener. After use, wipe the chrome finish clean and store the wrench in a dry place to maintain corrosion resistance.

Usage recommendations

Use the STAHLWILLE 13 8 mm open-end wrench for routine tightening and loosening of small fasteners. Avoid using it as a hammer or prying tool. For frozen or rounded fasteners, inspect the fastener condition first and consider using a matching ring or socket tool if higher torque or better envelopment is required. Regularly clean and lightly lubricate contact surfaces to prolong service life.
