Pinless Universal Design

An ordinary ball type universal join has a structure with a pin type joint. Ko-kens universal joints are connected with mutually engaged hexahedrons. This connection disperses the load across whole outer circumference. The same durability is obtained with this design in comparison to the pin-type.

Nut Grip Technology

Our nut grip sockets are unique to Ko-ken and truly a revolutionary way of approaching this type of socket. Our fastener holds nuts and bolts in place without the use of magnets. Our system is built with a spring ring and ball bearings on opposing flats. When a nut or bolt is in the socket the ball bearings push out on the springs holding the nut/bolt in place. Our nut grip sockets can completely change a mechanics efficiency. If you lose a nut or bolt inside of an engine it can be quiet the headache to retrieve. With nut grip sockets that dilemma is completely eradicated.

Cost-effective alternative that works well..
I used these spark plugs on my 2018 Cub Cadet XT2 riding mower as part of the spring preparation. The spark plugs were well packed and arrive in great shape and at the appropriate gap. No issues with starting or operating the mower. These Harbot plugs turned out to be a great cost-effective option for me.
