Koken's 1/4" drive universal nut grip sockets are a unique product. These sockets have a spring tensioned detent ball that grips the fastener to the socket. It is a modern replacement to the use of dumdum, paper, or tape. These are starting sockets made for those maddening places where the fastener falls out of the socket. It is NOT A TORQUEING SOCKET! You will always use this with another socket to break loose and torque down the fastener. Available in six sizes,7mm, 8mm,10mm,12mm and 13mm &14mm. $27.00each or save $$ on the set purchase($149.95).
