What Is a Reverse Torx Bit

Torx-heads screws are used in auto manufacturing and machinery because they provide the best grip for application and removal. Reverse torx are less common but are also used in automotive manufacturing.

Tightening & Loosening

Reverse torx bolts are particularly capable of handling torque. The deep-set grooves prevent slippage and stripping often encountered with flat-head or Phillips-head screws. Increased torque means that screws and bolts will hold tighter in locations with high tension and strong vibrations.

Setting the Bolt

Anyone who works on cars knows the difficulty of threading a bolt or screw in a hard-to-reach place. Torx are designed to be easier to start because they do not move on the end of the ratchet or wrench when held up to a thread. This is also a result of the deep notches.

Common Uses

The most common use of torx bolts requiring a female bit is as a wheel lock on American automobiles. Typically one of the lug nuts on each wheel is replaced with a torx bolt to prevent thieves from removing the wheel easily.
