FAQ
Q1: What is the difference between a bit socket set and a regular socket set?
A: Regular socket sets mainly handle standard hex bolts and nuts, while bit socket sets are specifically designed for non-standard bolts such as Torx, square, triangle, and 12-point. Using both together covers all bolt types in engine and chassis applications.

Q2: What do S5/16 and S3/8 mean for square bits?
A: S stands for Square, and 5/16 and 3/8 are imperial sizes, approximately 7.94mm and 9.53mm respectively. These two pieces are mainly used for imperial square bolts on certain American vehicle chassis and drivetrains.

Q3: Which vehicle models is the triangle bit 10mm compatible with?
A: The triangle bit is mainly used for triangle bolts on the chassis suspension systems of certain European vehicles (such as VW, Audi, BMW, Mercedes-Benz). Please confirm specific compatibility based on your actual repair needs.

Q4: What is the special use of the 12-point bit M16?
A: The M16 12-point bit is used for large 12-point bolts in chassis and suspension systems. The 12-point design provides more contact points than hex, allowing it to handle greater torque, making it suitable for heavy-duty bolt removal and installation.

Q5: What is the difference between a sliding T-handle and a ratchet wrench?
A: The sliding T-handle (198mm) operates through manual push-pull motion, ideal for situations requiring precise torque control, such as precision bolts inside the engine. A ratchet wrench is suited for rapid continuous turning. Using both together maximizes efficiency.

Q6: What is the difference between hex bit sockets and hex sockets?
A: Hex bit sockets feature a solid spline shaft design that inserts into the bolt’s internal recess to drive it; hex sockets have an external sleeve design that fits over the bolt. They are used for different types of hex bolts.
