46pc 1/4" Metric Socket Set Heat-Treated

This 46-piece 1/4" metric socket set combines chrome vanadium material integrity with rigorous heat treatment — hardening followed by controlled tempering — to achieve balanced hardness and toughness. Final polishing ensures smooth mating with fastener flats and improved resistance to surface oxidation. All parts are dimensionally verified against ISO 1174-1 and DIN 3120 standards for 1/4" drive tools. Contents breakdown: 13 standard sockets (4, 4.5, 5, 5.5, 6, 7, 8, 9, 10, 11, 12, 13, 14mm); slotted bit sockets (4, 5.5, 7mm); Phillips (PH1, PH2, PH3); Pozi (PZ1, PZ2, PZ3); hex bit sockets (3, 4, 5, 6, 7, 8mm); Torx sockets (T10, T15, T20, T25, T30, T40); hex keys (1.5, 2, 2.5mm); 1 universal joint; 2 rigid extensions (2", 4"); 1 flexible 6" extension; 1 sliding T-bar; 1 quick-ratchet handle; 1 6" spinner handle; 1 bit adaptor; and 1 reinforced plastic case with snap-fit lid and size-indexed layout.
