Q1. How do I choose the correct Star Outside and Square Inside dimensions?
You should measure the outer diameter of your star-shaped drive head and the inner width of your square mating tool. Match these dimensions with our specification table to find the perfect fit.
Q2. What does the "Height" specification refer to?
The height refers to the overall vertical length of the adapter socket, ranging from 12mm for low-profile applications up to 38mm for deep-reach requirements.
Q3. Are there custom sizes available if my required dimensions are not listed?
Yes, we offer customization options for bulk orders. Please contact our support team with your specific Star Outside, Square Inside, and height requirements.
Q4. What material are these adapters made of to ensure durability?
Our adapters are manufactured using high-grade, heat-treated alloy steel (such as Chrome Vanadium or Chrome Moly) to handle high torque applications and prevent wear.
Q5. Can these specifications be used with impact wrenches?
Sizes with larger square inside drives (e.g., 19mm and 22mm) are structurally designed to withstand impact tool forces, whereas smaller sizes are ideal for hand tool operations.
Q6. What is the manufacturing tolerance for these dimensions?
All components are manufactured to strict industrial standards with a precise tolerance range of ±0.05mm to guarantee a secure, non-slip connection.
