Fasteners sit behind brackets, inside frames, and under harnesses, where a conventional ratchet, socket, and bit stack is too tall to fit. The MDDA64S 64-Pc RPT™ 1\/4\" Drive Low Profile Master Dual Action Driver (DAD) Set is the complete compact answer: 59 DAD bits across hex, star, Star Plus, and triple square profiles, the DFRA6572 7\/16\" Hex Flex-Head Low Profile Ratchet built to drive them, and the adapters that tie the system into the rest of your toolbox. It is the first 1\/4\" master set to include this ratchet, the first to bring Star Plus into the DAD lineup, and it debuts sizes available only in this set: Star Plus IP6 and IP8, Star T6, and Hex 1.5mm and 1\/16\".\u003c\/p\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eWhat's in the set\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003eDual Action Driver bits\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetric Hex:\u003c\/strong\u003e 1.5mm (exclusive), 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSAE Hex:\u003c\/strong\u003e 1\/16\" (exclusive), 5\/64\", 3\/32\", 7\/64\", 1\/8\", 5\/32\", 3\/16\", 7\/32\", 1\/4\", 5\/16\", 3\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStar (Torx compatible):\u003c\/strong\u003e T6 (exclusive), T8, T10, T15, T20, T25, T27, T30, T40, T45, T47, T50, T55, T60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStar Plus:\u003c\/strong\u003e IP6 (exclusive), IP8 (exclusive), IP10, IP15, IP20, IP25, IP27, IP30, IP40, IP45, IP50, IP55, IP60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple Square:\u003c\/strong\u003e M4, M5, M6, M7, M8, M9, M10, M12, M13, M14\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eDrive tools and adapters\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDFRA6572: 7\/16\" Hex Standard Flex Head Low Profile Ratchet.\u003c\/strong\u003e Engages each DAD bit directly on its external hex through a pass-through retention cavity, for a combined stack height of just 22mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDDA32A: 7\/16\" Hex Drive to 1\/4\" Square Drive Adapter (new).\u003c\/strong\u003e Lets the low profile ratchet run standard 1\/4\" drive sockets and accessories.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDDB32A: 7\/16\" Hex Drive to 3\/8\" Square Drive Adapter (new).\u003c\/strong\u003e Extends the ratchet to 3\/8\" drive sockets and accessories.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDDA32BA: 7\/16\" Hex Drive to 1\/4\" Hex Drive Bit Adapter.\u003c\/strong\u003e Open compatibility with any standard 1\/4\" hex shank bit, so the ratchet covers profiles beyond the set.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLPASA: 1\/4\" Drive Spinner Adapter (new).\u003c\/strong\u003e Fast finger tightening and loosening before and after final torque.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEverything is packaged in a durable GripEdge case with a removable EVA foam tray for clean organization, quick inventory checks, and fast resets.\u003c\/p\u003e\n\u003ch3\u003eThe engineering behind the grip\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPT™ tooth geometry that loads inward.\u003c\/strong\u003e Standard drivers concentrate stress on the fastener corners and push material outward until the recess rounds. The RPT™ profile relocates the contact point along the flank and directs force inward, forming a mechanical lock.
