Choosing the Right Screws and Bits for Your Cordless Impact Driver

When using an 18V 1/4 inch (6.35mm) hex chuck cordless impact driver, choosing the right screws and bits is crucial for efficient work and great results. Whether you're tackling home improvement projects, furniture assembly, or mechanical repairs, understanding which screws and bits work best with your driver can save time and ensure a secure fit. Let's explore the six most common types of screws and bolts in the U.S. and the bits you'll need for each.

1. Wood Screws

Common Sizes: #6, #8, #10
Required Bits: Phillips head or slotted head bits

Wood screws are designed for use in wooden materials, with a sharp, tapered thread that allows them to bite into the wood easily. These screws are commonly used for construction projects, cabinetry, and wood-based furniture assembly. Phillips head bits are the most commonly used, though slotted head bits may be necessary for certain applications.

2. Self-Tapping Screws

Common Sizes: #6, #8, #10
Required Bits: Phillips head or hex head bits

Self-tapping screws are engineered to drill their own hole as they are driven in. They are perfect for use in materials such as metal or plastic, where a traditional screw would require a pilot hole. Depending on the design of the self-tapping screw, you may need a Phillips or a hex head bit. The hex bits are particularly useful when dealing with larger screws or those made from harder materials.

3. Machine Screws

Common Sizes: #4, #6, #8, 1/4 inch
Required Bits: Phillips head, slotted head, or hex head bits

Machine screws are typically used for fastening metal or other hard materials. They often require nuts or pre-threaded holes for installation. Depending on the specific type of machine screw, you might need a Phillips, slotted, or hex head bit. Machine screws are found in a variety of industrial, automotive, and home repair tasks.

4. Drywall Screws

Common Sizes: #6, #8
Required Bits: Phillips head or Pozidriv head bits

Drywall screws are designed for use in drywall installation, with a fine thread for quick, easy driving into wood studs or metal framing. The most common bits for drywall screws are Phillips, though Pozidriv bits are becoming more popular because they provide better grip and reduce cam-out. The right bit will ensure a smooth installation without damaging the drywall.

5. Anchor Bolts

Common Sizes: 1/4 inch, 3/8 inch, 1/2 inch
Required Bits: Hex head or Phillips head bits

Anchor bolts are used to secure materials to concrete, brick, or stone. These heavy-duty fasteners are crucial for tasks such as securing furniture to walls or installing heavy equipment. Hex head bits are the best choice for anchor bolts, providing a solid grip for high-torque driving.

6. Cross Slot Screws

Common Sizes: #4, #6, #8
Required Bits: Phillips head bits

Cross slot screws, often referred to as "cloverleaf" screws, are widely used in furniture assembly and electronics. These screws have a cross-shaped slot and typically require Phillips head bits for proper driving. They're also commonly used in appliances and devices where the screw needs a secure fit and high torque.
