Facom 40B Series Slim Metric Combination Spanner Set - 12 Pc

The OGV(r) profile is a specialized design on the wrench's contact surface that ensures better grip on the fastener head. It provides more surface area contact compared to traditional designs, leading to better torque transmission, reduced slippage, and less risk of damaging the fastener.

The 15-degree offset on the ring end helps protect your knuckles when working near flat surfaces or in tight spaces. The 15-degree offset handle also minimizes the angle needed to reposition the wrench, allowing for more continuous turning in confined areas.

The spanners feature a matt chrome finish, indicating they are typically made from high-strength steel (often chrome-vanadium steel) with a protective and corrosion-resistant chrome plating.

No, this set is specifically designed for metric fasteners. Using them on imperial fasteners can damage both the spanner and the fastener due to the size mismatch.

Facom tools are known for their durability and professional quality. While specific warranty terms can vary by region and retailer, Facom generally offers a lifetime warranty against manufacturing defects on many of its hand tools. It is advisable to check the warranty details provided by your specific point of purchase.

The set comes with a storage clip which is ideal for keeping the spanners organized and readily accessible. Store them in a dry toolbox or work area to prevent corrosion and protect the finish.

The Facom 40B series is designed for professional use and offers excellent durability. For extremely heavy-duty or continuous industrial applications, other specialized Facom series might be considered, but this set is robust for demanding professional tasks.

Ensure you are using the correct metric size for the fastener. Check the OGV(r) profile for wear; if significantly worn, the spanner may need replacement.

Utilize the 15-degree offset handle and ring end. Try repositioning the wrench slightly to find the optimal angle for leverage. The slim design should aid access; ensure no obstructions are present.

Wipe the spanner clean with a soft cloth and apply a light coat of tool oil. Store in a dry environment. The matt chrome finish offers good resistance, but prolonged exposure to moisture can still cause minor surface rust.

Confirm you are using the correct size and that the OGV(r) profile is fully engaged with the fastener. Ensure the fastener head is not damaged or rounded. Apply steady, controlled force.
