This Laser 0155 6 Piece AF Combination Spanner Set is designed for classic car enthusiasts and mechanics working on British or American vehicles. Its key benefit is the Bi-Hex profile, which offers superior grip on tight fixings and reduces the risk of damaging nuts and bolts. A potential caveat is that the set covers a specific range of AF sizes (3/8"" to 11/16"" ), so verify compatibility with your specific needs. The set includes essential AF sizes, is made from durable chrome vanadium, and comes with a convenient storage clip.

AF stands for 'Across Flats,' which is the measurement across the parallel sides of a hexagonal or square fastener head. It refers to the Imperial sizing system commonly used for tools and fasteners.
No, these spanners are specifically sized for Imperial (AF) fasteners. Using them on metric bolts can lead to a poor fit, damage to the bolt head, and potential injury.
Clean the spanners with a cloth after use to remove dirt and oil. Store them on the provided clip in a dry location to prevent rust. A light application of oil can add protection against corrosion.
The Bi-Hex profile (double-hex) provides 12 points of contact with the fastener compared to the 6 points of a standard hex socket. This offers a stronger grip, requires a smaller turning arc, and significantly reduces the risk of damaging or rounding off the fastener head, especially in tight spaces.
They are ideal for classic cars and motorcycles manufactured in the UK and USA, which typically use Imperial (AF) fasteners. This includes many British marques and American models from the 1950s through the 1980s and beyond.
While made from durable chrome vanadium, they are intended for general automotive maintenance. For extremely high-torque applications or seized fasteners, impact sockets or specialized breaker bars might be more appropriate to avoid damaging the spanners or the fastener.
Yes, the set comes with a handy storage clip that keeps all the spanners organized and secure, making it easy to store in a toolbox or hang on a wall.
Ensure you are using the correct AF size. Verify the fastener is not damaged or rounded. Clean both the spanner jaws and the fastener head.
The Bi-Hex profile is designed to improve access, but for extremely confined spaces, specialized offset wrenches may be required. Ensure no obstructions are present.
Clean the affected area with a light abrasive (e.g., fine steel wool) and a rust inhibitor. Wipe dry and store in a dry place. A light coat of oil can offer protection.
Check if the spanner is fully engaged onto the fastener. If the spanner itself appears damaged or excessively worn, it may need replacement to prevent fastener damage.
Setup: This is a hand tool set and requires no setup beyond removing the spanners from their storage clip. Ensure you select the correct size spanner for the fastener to avoid damage.
Compatibility: The Laser 0155 set is primarily designed for fasteners with Imperial (AF - Across Flats) measurements, specifically 3/8", 7/16", 1/2", 9/16", and 11/16" sizes. It is ideal for use on classic vehicles manufactured in countries that used the Imperial system, such as the UK and USA. It is not directly compatible with metric fasteners unless an adapter is used, which is not recommended for precision work.
Care: To ensure longevity and optimal performance:
