Marine Fasteners Flat Head Machine Screws

Marine Fasteners flat head machine screws are countersunk fasteners for marine and boating hardware. The flat, tapered head sits flush with or slightly below the mounting surface once installed. The result is a clean, low-profile finish with no raised head to snag lines, clothing or gear. They are also sold as countersunk machine screws.

Key Features:

• Flat head design: the conical underside of the head seats in a countersunk hole for a flush finish.
• Machine screw threads: uniform threads are made to mate with tapped holes or with nuts. They are not self-tapping wood or sheet metal threads.
• Marine-focused line: offered by Marine Fasteners for boat hardware, fittings, brackets and panels.
• Multiple sizes: choose the diameter and length that suit your application.

Pair these screws with matching nuts and washers. Use a countersunk hole that matches the head so the screw seats fully. To limit galvanic corrosion, avoid putting dissimilar metals in direct contact where you can.
