Features:
【SUPERIOR CR-MO STEEL】 Constructed with heat-treated forged chrome molybdenum steel material, impact adapter set features high hardness and durability, and can withstand the test of different jobs.
【DURABLE & RECOGNIZABLE MARKING】 Different from the traditional black oxide coating adopted by others, our socket adapter set is made of black manganese phosphate coating, which has excellent corrosion resistance and rust resistance, so that you can use and keep it for a long time. Laser markings and stamped markings make all model numbers easy to keep, read and quick identification.
【SAFE & FIRM】 A spring-loaded ball brake can lock your socket in place and fix the through hole to prevent it from falling, providing excellent stability and execution. The through hole on the drive end securely locks the adapter to the drive tang.
【WIDE APPLICABILITY】 Complete impact drive socket adapter set, with convenient conversion and strong compatibility, can meet all your needs. Designed for drivers, wrenches and ratchets. It can be used with pneumatic tools, electric tools or driving tools.
【QUALITY GUARANTEE】 It meets ANSI standards. We provide 1 year quality warranty. All impact socket adapters have been rigorously tested to ensure the best performance and durability. If you have any questions, please feel free to contact us.
【NOTE】Please rest assured that this is a normal new set, if there is a layer of oil on the socket of the set you received. It's a specially painted anti-rust oil to protect the product. Please be careful when using it.
