FAQ
What does 72-tooth ratchet mean?
72-tooth means the ratcheting mechanism requires only 5 degrees of swing to engage the next tooth. Lower tooth counts need more swing space. 72-tooth allows fast work in very tight spaces where a full rotation is impossible.
Are these wrenches suitable for high-torque applications?
The LD-159 ratchet wrenches are rated for standard automotive and mechanical torque applications. For extremely high torque loads exceeding the ratchet mechanism capacity, use a standard combination wrench or socket set instead to prevent ratchet damage.
What is the difference between 6-point and 12-point box ends?
12-point box ends engage at 30-degree intervals, allowing faster engagement on hex fasteners. 6-point box ends engage at 60-degree intervals and provide more surface contact, reducing rounding risk on stubborn or damaged bolts. The LD-159 uses 12-point for versatility.
Can individual wrench sizes be ordered separately?
Yes, individual wrench sizes from the LD-159 set are available for separate ordering. Custom size combinations in roll pouches are also welcome for bulk orders.
