How To Use a Torx Screwdriver

Joel Camassar

Torx Screwdrivers, also known as Star screwdrivers were developed in 1967. Inventors were looking for an alternative to a Phillips screwdriver. Torx screwdrivers design allow for a more even distribution of force while tightening or loosening a screw and prevents the cam-out that often happens with Phillips screws. Star screwdrivers have gained popularity steadily since their conception over 50 years ago. Today you can find them on motorcycles, computers, consumer electronics, cars, and more. Using a torx screwdriver in any application is easy, but in case you need a refresher course, here is how to use a Torx Screwdriver:

Step 1: Purchase a Chapman Mity Master Set. Chapman offers Star sizes S6-S40 and the Mity Master Set comes with the most diverse size selection.

Step 2: Determine The Screw Type. Does it look like a 6-point star? If it does, we’re ready for step 3.

Step 3: Determine The Screw Size. Star bits come in a variety of sizes, but you’ll know the correct bit by simply taking the Chapman bits out of their case and pressing them into the screw head. When you find the correct size, it will be a perfect fit.

Step 4: Choose your tools. The Mity Master Set comes with all interchangeable tools. Depending on the amount of space you have or want around the screw, you can use the ratchet, handle, ratchet, or a combination. Insert the bit into whichever tool you choose.

Step 5: Apply gentle pressure and turn your tool clockwise to tighten, counterclockwise to loosen.

Step 6: When the screw is secure or loosen to your satisfaction, remove the tool and bit from the screw. 

And that’s all! Using a Torx or Star screwdriver can be as easy as any other tool. Chapman offers many different sets that include Star bits with our signature knurled end to allow for finger tightening as well. You can find them here.
