The ball end lets the tool engage a recessed or obstructed socket head screw off-axis, but a standard-length bit socket often cannot get the ball far enough into the pocket, and a 6\" long socket is more tool than a crowded bay has room for. The MBH31SLS splits the difference with 3\" semi-long RPT™ Ball Hex bit sockets that reach into recessed hardware while staying maneuverable in tight spaces. This master set carries the full semi-long Ball Hex range in one case: 17 metric sizes from 3mm through 19mm and 14 SAE sizes from 1\/8\" through 3\/4\", across 1\/4\", 3\/8\", and 1\/2\" drive. It combines both 8-PC semi-long sets and adds fifteen 1\/2\" drive sizes beyond them, for the large socket head cap screws on suspension, driveline, and industrial equipment that no other ball hex socket reaches at an angle.\u003c\/p\u003e\n\u003cp\u003eEvery socket carries second-generation RPT™ Ball Hex geometry, so engagement behavior is consistent across the set, and each size sits on the square drive it belongs on, so the drive tool is never oversized for the fastener.\u003c\/p\u003e\n\u003ch3\u003eWhat's in the set\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\/4\" drive:\u003c\/strong\u003e 3mm, 4mm, 5mm, 6mm, 1\/8\", 9\/64\", 5\/32\", 3\/16\", 7\/32\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/8\" drive:\u003c\/strong\u003e 7mm, 8mm, 9mm, 10mm, 1\/4\", 5\/16\", 3\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\/2\" drive:\u003c\/strong\u003e 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 7\/16\", 1\/2\", 9\/16\", 5\/8\", 11\/16\", 3\/4\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe engineering behind the grip\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPT™ Ball Hex geometry.\u003c\/strong\u003e A standard ball end contacts the fastener on a narrow band and pushes material outward as it turns off-axis, which is how a ball hex rounds a socket head.
