1/4-20 x 3/4 Six Lobe Flat Head Type F Floor Board Screws, Black Phosphate, 3,000-Pack

These Type F floor board screws are for buyers who need thread-cutting fasteners for floor board and other fastening work. Their flat heads are suited to applications where a fastener should not extend above the mating surface.

Each screw has a 1/4-20 thread size, a 3/4-inch length, a six-lobe drive, and a flat head with a black phosphate finish. Type F thread-cutting screws are used in heavy-gauge sheet metal, aluminum, zinc and lead die castings, cast iron, brass, and plastic. This package contains 3,000 screws.

Key Features:

• Type F thread-cutting design: Cuts threads in compatible materials for fastening without a preformed thread.
• Flat head: Helps keep the fastener from protruding above the mating surface.
• Six-lobe drive: Provides a defined drive interface for installation.
• 3,000-piece package: Supplies a large quantity for high-volume fastening needs.

Choose these 1/4-20 x 3/4 Type F screws when a black phosphate, flat-head, six-lobe fastener is needed for compatible thread-cutting applications.
