The Snap-on 12-pc 1/4" 12-point drive fractional low profile ratchet/socket set (No. 112RT) works well on under cowls on late model pickup trucks, under-dash cramped quarters and transmission bolts on transverse mounted engines. Tools feature 72 gear teeth requiring minimal movement in tight areas and a low profile, easy-action reverse lever that won't get in the users way. Sockets can be used with 1/4" extensions or any 1/4" ratchet. The 11mm hex on sockets adds flexibility where they can be used on any 11mm ratcheting wrench such as stubby or flex.
