Planning Guide

Plan the right fit before choosing

Start With the Installation Goal

Select a head style for a flush result

Countersunk flat heads are represented across the category for installations that call for the screw to sit flush with the work surface. Other flat head options are described as helping keep the fastener from extending or protruding above the mating surface.

  • Choose countersunk styles for a flush finished surface after installation.
  • Use flat head designs where projection above the mating surface is unacceptable or should be minimized.
  • Confirm the screw is intended for the material being fastened, such as plywood, lumber, other wood, or resilient materials as listed.
Compare the Screw Details

Match the size and drive to the task

The represented range includes #6, #8, #9, #10, and #12 screws in lengths from 3/4 inch through 3 inches. Phillips-drive models are widely represented, and a #6 x 1-1/2 inch square-drive option is also available.

  • Compare both screw number and length, including #6 x 1 inch through #12 x 3 inches.
  • Choose Phillips-drive screws when using a compatible Phillips driver.
  • Choose the square-drive option when square-drive installation is required.
  • Look for aggressive threads when strong grip in plywood, lumber, and other wood materials is a priority.
Plan the Pack Quantity

Choose a count that fits the fastening workload

Many options come in 100-piece or 100-count packs for project, replenishment, maintenance, and multi-fastener assembly needs. Larger #8 and #9 options provide 1,800 or 2,000 matching screws for ongoing work requiring higher quantities.

  • 100-count packs suit many project and maintenance needs.
  • An 1,800-count #8 x 2 inch option is available for ongoing fastening needs.
  • A 2,000-count #9 x 1-1/2 inch option is available for jobs requiring many matching screws.
