The Yato YT-38752 is a professional-grade 26-piece socket set designed for heavy-duty mechanical applications, featuring a 1/2-inch square drive system. The set is manufactured by Yato, an international brand originating from Poland known for high-quality workshop tools.[1] [3] The components are primarily constructed from Chromium-Vanadium steel (specifically CrV6140 and CrV50BV30 grades), which provides high torque strength and resistance to atmospheric corrosion.[1] [2] [3]

According to www.iAsk.Ai - Ask AI:

The set is characterized by its "AS-Drive" system, a peripheral drive technology that allows for the transmission of higher torque while protecting the edges of the nuts from rounding.[3] [5] The total weight of the kit is approximately 4.0 to 4.1 kg, and it is housed in a durable carrying case measuring roughly $31.00\mathrm{\text{cm}}\times 24.00\mathrm{\text{cm}}\times 7.00\mathrm{\text{cm}}$.[3] [5]

Detailed Component Breakdown

The 26 pieces included in the YT-38752 set are logically organized to cover a wide range of automotive and industrial fasteners:

• Hexagonal Sockets (20 Pieces): The set includes 6-point sockets in the following metric sizes: 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 27, 30, and 32 mm.[1] [5]
• Ratchet Handle: A 255 mm long 1/2" drive ratchet featuring an ergonomic grip designed to reduce user fatigue during extended use.[1] [2]
• Extensions: Two extension bars measuring 127 mm (approx. 5 inches) and 250 mm (approx. 10 inches) for reaching recessed bolts.[1] [3]
• Sliding T-Bar: A 255 mm sliding T-handle used for applying high manual torque.[2] [5]
• Universal Joint: A 1/2" drive swivel joint for accessing fasteners at difficult angles.[1] [3]
• Spark Plug Socket: A specialized 21 mm socket designed for the removal and installation of spark plugs.[1] [5]

Technical Specifications and Origin

The tools feature a fully polished finish for easy cleaning and additional rust prevention.[5] While the brand is Polish, manufacturing for this specific model is noted to occur in China under strict quality assurance standards.[5] [6] As of early 2026, the set remains a staple for both DIY enthusiasts and professional mechanics due to its comprehensive size range and material durability.[2] [4]
