Designed for assembly and servicing of small precision mechanisms, this high‑performance socket set is ideal for electrical, electronic, ignition and refrigeration work. All sockets are bi‑hexagon unless stated, featuring a double knurl for a secure, non‑slip grip that allows rapid tool changes even when your hands are greasy or oily. The 12‑point bi‑hexagon side‑drive profile delivers higher torque and reduced fastener damage compared with standard sockets. Manufactured from durable chrome vanadium steel, each socket is fully chrome plated with a mirror finish for corrosion resistance and long service life. The aluminium‑free construction helps reduce the risk of sparking in sensitive environments. A chamfered leading edge ensures quick, easy fastener location, improving efficiency and precision in tight or hard‑to‑reach spaces. Suitable for professional engineers, mechanics and serious DIY users who demand reliable, accurate performance.
