TengTools TTESK73 socket set contains 73 professional tools and is suitable for everything from engine repairs to industrial maintenance. The set has square drive sizes in 1/4, 3/8 and 1/2, providing a wide range of applications. The set features three 72-teeth ratchets (1/4, 3/8, and 1/2), complemented by spinner handles in 1/4 and 3/8 sizes. A 450 mm 1/2 flex handle provides added torque for more challenging applications. A range of extensions, including 1/2 (63.5 mm and 150 mm), 1/4 (50 mm and 100 mm), and a 3/8 swivel extension (75 mm), complemented by universal joints in all three drive sizes simplifies access to confined spaces. Reducing adaptors and step-up adaptors (1/2F-3/8M, 3/8F-1/4M, and 3/8F-1/2M) enhance compatibility across tools. The metric socket selection covers 6-point and 12-point sockets, offering sizes from 4 mm to 24 mm across 1/4, 3/8, and 1/2 drives, with both standard and deep sockets. In addition, the kit has a 3/8 hex bit holder for 1/4 bits. The tool kit is manufactured for daily industrial use according to DIN and ISO standards, ensuring compliance with quality requirements and durability. The tools are held in place using three colour precision cut high-density EVA foam. The set is organised in a tool module size 4X4 (FOAM4X4), compatible with the TengTools Tool Control System.
