A: This socket extension bar set supports three standard drive sizes — 1/4" (6.35mm), 3/8" (10mm), and 1/2" (12.5mm) — making it compatible with the vast majority of ratchet handles, socket sets, sliding rods, and breaker bars available on the market. Q: Can these extension bars be used at an angle in tight spaces? A: Yes! Each bar can operate as a wobble extension bar, allowing it to work at a slight offset angle when clearance is limited — for example, when bolts are recessed or surrounded by obstructions. Simply switch to rigid mode for standard straight-drive applications. Q: What material are these socket extension bars made from? A: They are constructed from high-quality chrome vanadium steel with a chrome-polished surface. This combination delivers excellent strength, durability, and resistance to rust and corrosion, making them suitable for both professional mechanics and DIY enthusiasts. Q: What lengths are available for the socket extension bars? A: The socket extension bars are available in four lengths: 50mm, 100mm, 150mm, and 250mm. This range covers everything from shallow recesses to deeply set fasteners, giving you the flexibility you need for a wide variety of tasks.
