BGS 4056 Tool Insert | 12-Point Socket Set 1/4″ and 1/2″ 29 pcs.

The BGS 4056 tool insert is a professional 29-piece set of 12-point sockets with 1/4″ (6.3 mm) and 1/2″ (12.5 mm) square drives, engineered for rigorous daily operation in automotive repair facilities, mechanical workshops, and industrial maintenance departments. Every socket is drop-forged from high-grade chrome-vanadium alloy steel (Cr-V) and subjected to precise heat treatment, ensuring exceptional torsional strength and resistance to cracking under heavy torque loads. The satin matte chrome finish delivers reliable protection against corrosion and harsh workshop fluids, while the precision 12-point socket profile ensures optimum contact with fasteners to minimize the risk of corner rounding, even in restricted clearances.

The set is cleanly organized in a two-tone, oil- and chemical-resistant EVA foam insert formatted to standard 1/3 drawer dimensions (408 × 189 × 32 mm), making it fully compatible with modular workshop trolleys from leading manufacturers (BGS, Sonic, RETTER, FTools, HAZET). Precision CNC-milled recesses with high-contrast size markings enable instant detection of missing tools, speeding up vehicle turnaround times and maintaining flawless order at the workstation. Choosing authentic BGS Technic tools through GGM Tools guarantees lasting performance, refined German engineering, and maximum workshop efficiency.

Which tool trolleys are compatible with this insert?

The BGS 4056 insert features standard modular 1/3 drawer dimensions (408 × 189 × 32 mm). It fits perfectly into drawers of most professional tool trolleys (including BGS, Sonic, RETTER, FTools, HAZET, KS Tools), where three such modules seamlessly fill a full standard drawer.

What is the benefit of 12-point sockets over 6-point sockets?

A 12-point profile allows engagement with fasteners every 30 degrees instead of 60 degrees. This provides double the positioning options in restricted spaces around engine bays or suspension components. 12-point sockets fit both 12-point and standard 6-point bolt heads.

What steel is used for the sockets and are they corrosion resistant?

Sockets are drop-forged from high-grade chrome-vanadium alloy steel (Cr-V). The satin matte chrome plating provides superior corrosion resistance against moisture and automotive chemicals while ensuring a secure grip with greasy hands.

Is the foam inlay resistant to automotive chemicals?

Yes, the two-color high-density EVA foam tray is formulated to resist mineral oils, gasoline, brake fluid, and common workshop solvents.
