The VIM Tools 4-pc Firm Flex Drive 1/4" x 11mm UJ Kit, No. FFDD400K, includes a 10mm socket, an E10 inverted Torx socket, a 1/4” square drive adapter, and a 1/4” hex bit adapter. All four are spring-loaded universal joints (Firm Flex). The overall length of the sockets are 1-1/4” and the 1/4” adapters are 1-1/2”, but when inserted in an 11mm wrench, the dual drive reduces the overall length by 1/4”. The FFDD400K allows technicians to reach fasteners in spaces that would normally require the disassembly of various parts, getting the job done quicker and with ease, the company says.
