TAJIMA TSK-T1721-12K Dual Impact Socket for Structural Work
The TAJIMA TSK-T1721-12K 12-point dual-ended pass-through impact socket is a super-premium fastening tool built to Japanese engineering standards, designed specifically for pneumatic and electric impact wrenches. It uniquely combines the two most popular sizes used in structural work—17 mm and 21 mm—into a single piece. Featuring a thru-hole design, it eliminates issues with long threaded studs bottoming out inside the socket. The socket is forged from chrome molybdenum steel (Cr-Mo), which provides superior toughness and resistance to repeated impact torque compared to standard steel, preventing cracking and expansion during heavy industrial work.
Features
2-in-1 Dual Size Impact Socket: 2-in-1 dual socket sizes 17 mm and 21 mm, instantly reversible for use, reducing the burden of carrying and swapping tools, and increasing on-site assembly speed.
Premium CR-Mo Steel (Chrome Molybdenum): Forged from specially hardened chrome molybdenum steel, highly resistant to accumulated impact (High Impact Resistance), crack-resistant, ensuring maximum safety when used with high-torque impact wrenches.
12-Point Double Hex: 12-point socket design allows faster and easier engagement with fastener heads in confined spaces or blind spots, offering more frequent engagement angles than standard 6-point sockets.
Thru-Hole Structural Design: Hollow pass-through core design allows smooth tightening of nuts down long threaded rods, bolts, or protruding studs without restrictions.
High-Visibility Color Band: Equipped with prominent size-identifying color bands around the body along with clear laser-etched size markings, helping technicians quickly and accurately switch between 17 mm and 21 mm.
Torsion Absorption Structure: Specially proportioned core structure disperses stress and absorbs excess impact force, delivering full torque to the fastener head while protecting the tool's drive anvil.
Applications (Suitable for)
Assembly, fastening, and installation of scaffolding structures on high-rise construction sites.
Installation of large steel structures, factory roof purlins, and beams.
Maintenance of truck and automotive suspension systems, such as tightening U-bolts or leaf spring bolts with long threads.
Installation of industrial water pipelines, fire protection pipes, and large structural anchor bolts.
Maintenance of heavy machinery, mechanical equipment, and industrial worksites requiring speed and safety.
