Things You'll Need:
- Tape measure
-
Step 1
Measure the depths of the surfaces you need to combine. Determine screw length to ensure the screw clears both surfaces without piercing through the back.
-
Step 2
Figure out the screw type based on surfaces, use of washers or nuts, tapped or untapped holes and insertion method. Wood screws pierce and grip the surface (wood or drywall) with a sharp point, deep threads and a flush head. Machine and sheet metal screws require a pre-drilled and tapped hole, have fine threads and a rounded head.
-
Step 3
Learn the basics about screws. Flat head and Phillips screws are available as wood, machine, sheet metal and most other screw types. Flat head screws are best used with a manual screwdriver. Use Phillips head screws with either a power or manual screwdriver.
-
Step 4
Count how many screws you need. Double-check or pad the count to save extra trips to the hardware store.
-
Step 5
Go to the hardware store and locate the hardware/screw section. Bring your list of measurements, styles, and quantities. Find the desired length, style, head, metal and finish for your job.
